The Choice

71UNpRo4ZML._SL1500_

By Suzanne Woods Fisher

With a vibrant, fresh style Suzanne Woods Fisher brings readers into the world of a young Amish woman torn between following the man she loves–or joining the community of faith that sustains her, even as she questions some of the decisions of her elders. Her choice begins a torrent of change for her and her family, including a marriage of convenience to silent Daniel Miller. Both bring broken hearts into their arrangement–and secrets that have been held too long.

Filled with gentle romance, The Choice opens the world of the Amish–their strong communities, their simple life, and their willingness to put each other first. Combined with Fisher’s exceptional gift for character development, this novel, the first in a series, is a welcome reminder that it is never too late to find your way back to God.

ISLAND BREEZES

The Choice was certainly a good name for this book. Actually, there were a lot of choices for more than one character before getting to the major choice that Carrie had to make.

Will she decide to leave the Amish community and live among the English? This decision isn’t just a one time thing. It’t a decision that has to be made more than once over the years.

Love and heartbreak influence the decisions that are made in this book. Will any of these people figure out how to follow his or her heart? Stay tuned for some surprises along the way. This is the first book in the Lancaster County Secrets series. I’m looking forward to many more.

Be Authentic Review

January 25th, 2010

 

I like Warren Wiersbe’s “Be” books.  These commentaries use a style and format that is conducive to understanding the Bible.  Be Authentic guides us through the lives of Isaac, Jacob and Joseph and teaches us how to become authentic believers.  

 

Authentic believers aren’t perfect, and they aren’t all alike.  But, they all do depend on the grace of God, and they all make a difference in their world.

 

Studying the lives of these three men and their defining moments as told in Genesis 25-50, is teaching me how to become authentic.  Read this book and get real!

I hate and abhor falsehood; but I love your law.

 

Seven times a day I praise you for your righteous ordinances.

 

Great peace have those who love your law; nothing can make them stumble.

 

I hope for your salvation, O Lord, and I fulfill your commandments.

 

My soul keeps your decrees; I love them exceedingly.

AND NOW…THE FIRST CHAPTER:

Like Father , Like Son—Almost

(Genesis 25—26)

Isaac was the son of a famous father (Abraham) and the father of a famous son (Jacob), and for those reasons he is sometimes considered a lightweight among the patriarchs. Compared to the exploits of Abraham and Jacob, Isaac’s life does seem conventional and commonplace. Although he lived longer than either Abraham or Jacob, only six chapters are devoted to Isaac’s life in the Genesis record, and only one verse in Hebrews 11 (v. 9).

Isaac was a quiet, meditative man (Gen. 24:63), who would rather pack up and leave than confront his enemies. During his long life, he didn’t travel far from home. Abraham had made the long journey from Haran to Canaan, and had even visited Egypt, and Jacob went to Haran to get a wife, but Isaac spent his entire adult life moving around in the land of Canaan. If there had been an ancient Middle East equivalent to our contemporary “jet set,” Isaac wouldn’t have joined it.

However, there are more Isaacs in this world than there are Abrahams or Jacobs, and these people make important contributions to society and to the church, even if they don’t see their names in lights or even in the church bulletin. Furthermore, Isaac was a living part of the divine plan that eventually produced the Jewish nation, gave us the Bible, and brought Jesus Christ into the world, and that’s nothing to be ashamed of.

Isaac wasn’t a failure; he was just different. After all, the people in each generation have to find themselves and be themselves and not spend their lives slavishly trying to imitate their ancestors. “Men are born equal,” wrote psychiatrist Erich Fromm in Escape from Freedom, “but they are also born different.” Discovering our uniqueness and using it to the glory of God is the challenge that makes life what it is. Why be a cheap imitation when you can be a valuable original?

No generation stands alone, because each new generation is bound to previous generations whether we like it or not. Isaac was bound to Abraham and Sarah by ties that couldn’t be ignored or easily broken. Let’s look at some of those ties and discover what they teach us about our own life of faith today.

HE RECEIVED HIS FATHE R’S INHERITANCE (25:1–18)

Abraham recognized his other children by giving them gifts and sending them away, thereby making sure they couldn’t supplant Isaac as the rightful heir. Along with his father’s immense wealth (13:2; 23:6), Isaac also inherited the covenant blessings that God had given Abraham and Sarah (12:1–3; 13:14–18; 15:1–6). Isaac had parents who believed God and, in spite of occasional mistakes, tried to please Him.

Abraham’s firstborn son, Ishmael (chap. 16), wasn’t chosen to be the child of promise and the heir of the covenant blessings. God promised to bless Ishmael and make him a great nation, and He kept His promise (17:20–21; 25:12–16); “But my covenant will I establish with Isaac” (17:21;

Rom. 9:6–13). Ishmael was on hand for his father’s funeral (Gen. 25:9), but he wasn’t included in the reading of his father’s will.

Ishmael pictures the “natural” or unsaved person (1 Cor. 2:14), who is outside the faith and hostile to the things of God. But Isaac pictures those who have trusted Jesus Christ and experienced the miraculous new birth by the power of God (1 Peter 1:22–23). “Now we, brethren, as Isaac was, are the children of promise” (Gal. 4:28). Ishmael was born a slave, but Isaac was born free (4:21–31; 5:1–2); and Ishmael was born poor, but Isaac was born rich. Every believer in Jesus Christ shares all the blessings of the Spirit in Christ (Eph. 1:3) and is part of Christ’s glorious inheritance (vv. 11, 18).

From the moment of birth, we’re all dependent on the older generation to care for us until we can care for ourselves. We’re also indebted to previous generations for guarding and handing down to us the knowledge, skills, traditions, and culture that are extremely important to daily life. Imagine what life would be like if each new generation had to devise the alphabet, invent printing, discover electricity, or design the wheel!

The most important part of Isaac’s legacy wasn’t the great material wealth his father had left him. Isaac’s most important legacy was the spiritual wealth from his father and mother: knowing and trusting the true and living God and being a part of the covenant blessings that God had graciously bestowed upon Abraham and Sarah and their descendants. How tragic it is when the children of devout Christian believers turn their backs on their priceless spiritual heritage and, like Ishmael and Esau, live for the world and the flesh instead of for the Lord!

HE PRAYED TO HIS FATHER’S GOD (25:19–34)

Genesis is a record of ten successive “generations.” Generations come and go, but the Lord remains and never changes. “Lord, You have been our dwelling place in all generations” (Ps. 90:1 NKJV).

A devoted home (vv. 19–20). When Isaac was forty years old, God selected Rebekah to be his wife (chap. 24; 25:20), and we have every reason to believe that they were both devoted to the Lord and to each other. The record indicates that Rebekah was the more aggressive of the two when it came to family matters, but perhaps that’s just the kind of wife Isaac needed. Whatever mistakes Isaac may have made as a husband and father, this much is true: As a young man, he willingly put himself on the altar to obey his father and to please the Lord (chap. 22; Rom. 12:1–2).

A disappointed home (v. 21). Isaac and Rebekah waited twenty years for a family, but no children came. The entire book of Genesis emphasizes the sovereignty of God and the wisdom of His “delays.” Abraham and Sarah had to wait twenty-five years for Isaac to be born; Jacob had to labor fourteen years to obtain his two wives; and Joseph had to wait over twenty years before he was reconciled to his brothers. Our times are in His hands (Ps. 31:15), and His timing is never wrong.

Like Abraham, Isaac was a man of prayer, so he interceded with the Lord on behalf of his barren wife. Isaac had every right to ask God for children because of the covenant promises the Lord had made to his father and mother, promises Isaac had heard repeated in the family circle and that he believed. If Rebekah remained barren, how could Abraham’s seed multiply as the dust of the earth and the stars of the heavens? How could Abraham’s seed become a blessing to the whole world (Gen. 12:1–3; 13:16; 15:5; 17:6)?

It has well been said that the purpose of prayer is not to get our will done in heaven but to get God’s will done on earth. Even though every Jewish couple wanted children, Isaac wasn’t praying selfishly. He was concerned about God’s plan for fulfilling His covenant and blessing the whole world through the promised Messiah (3:15; 12:1–3). True prayer means being concerned about God’s will, not our own wants, and claiming God’s promises in the Word. The Lord answered Isaac’s prayer and enabled Rebekah to conceive.

A distressed home (vv. 22–23). One problem soon led to another, because Rebekah’s pregnancy was a difficult one: The babies in her womb were struggling with each other. The Hebrew word means “to crush or oppress,” suggesting that the fetal movements were not normal. Since Rebekah wondered if the Lord was trying to say something to her, she went to inquire. Isaac was fortunate to have a wife who not only knew how to pray, but who also wanted to understand God’s will for herself and her children.

In salvation history, the conception and birth of children is a divinely ordained event that has significant consequences. This was true of the birth of Isaac (chaps. 18, 21), the twelve sons of Jacob (29:30—30:24), Moses (Ex. 1—2), Samuel (1 Sam. 1—2), David (Ruth 4:17–22), and our Lord Jesus Christ (Gal. 4:4–5). Conception, birth, and death are divine appointments, not human accidents, a part of God’s wise and loving plan for His own people (Ps. 116:15; 139:13–16).

Imagine Rebekah’s surprise when she learned that the two children would struggle with each other all their lives! Each child would produce a nation, and these two nations (Edom and Israel) would compete, but the younger would master the older. Just as God had chosen Isaac, the second-born, and not Ishmael, the firstborn, so He chose Jacob, the second-born, and not Esau, the firstborn. That the younger son should rule the elder was contrary to human tradition and logic, but the sovereign God made the choice (Rom. 9:10–12), and God never makes a mistake.

A divided home (vv. 24–28). Esau probably means “hairy.” He also had the nickname “Edom,” which means “red,” referring to his red hair and the red lentil soup Jacob sold him (vv. 25, 30). The twin boys not only looked different but they also were different in personality. Esau

was a robust outdoorsman, who was a successful hunter, while Jacob was a “home boy.” You would think that Isaac would have favored Jacob, since both of them enjoyed domestic pursuits, but Jacob was Rebekah’s favorite. Rebekah was a hands-on mother who knew what was going on in the home and could contrive ways to get what she thought was best.

It’s unfortunate when homes are divided because parents and children put their own personal desires ahead of the will of God. Isaac enjoyed eating the tasty game that Esau brought home, a fact that would be important in later family history (chap. 27). Isaac, the quiet man, fulfilled his dreams in Esau, the courageous man, and apparently ignored the fact that his elder son was also a worldly man. Did Isaac know that Esau had forfeited his birthright? The record doesn’t tell us. But he did know that God had chosen the younger son over the elder son.

A friend of mine kept a card under the glass on his office desk that read: “Faith is living without scheming.” Jacob could have used that card. Before his birth, he had been divinely chosen to receive the birthright and the blessing; thus there was no need for him to scheme and take advantage of his brother. It’s likely that Jacob had already seen plenty of evidence that Esau didn’t care about spiritual things, an attitude that made Esau unfit to receive the blessing and accomplish God’s will. Perhaps Jacob and his mother had even discussed the matter.

The name “Jacob” comes from a Hebrew word (yaaqob) that means “may God protect,” but because it sounds like the words aqeb (“heel”) and aqab (“watch from behind” or “overtake”), his name became a nickname: “he grasps the heel” or “he deceives.” Before birth, Jacob and Esau had contended, and at birth, Jacob grasped his brother’s heel. This latter action was interpreted to mean that Jacob would trip up his brother and take advantage of him. The prediction proved true.

The fact that God had already determined to give the covenant blessings to Jacob didn’t absolve anybody in the family from their obligations to the Lord. They were all responsible for their actions, because divine sovereignty doesn’t destroy human responsibility. In fact, knowing that we’re the chosen of God means we have a greater responsibility to do His will.

HE FACED HIS FATHER’S TEMPTATIONS (26:1–11)

True faith is always tested, either by temptations within us or trials around us (James 1:1–18), because a faith that can’t be tested can’t be trusted. God tests us to bring out the best in us, but Satan tempts us to bring out the worst in us. In one form or another, each new generation must experience the same tests as previous generations, if only to discover that the enemy doesn’t change and that human nature doesn’t improve. Abraham is mentioned eight times in this chapter, and you find the word “father” six times. Isaac was very much his father’s son. Abraham Lincoln was right: “We can not escape history.”

The temptation to run (vv. 1–6). When Abraham arrived in Canaan, he found a famine in the land and faced his first serious test of faith (12:10—13:4). His solution was to abandon the place God had chosen for him, the place of obedience, and to run to Egypt, thus establishing a bad example for his descendants who were prone to imitate him.5 The safest place in the world is in the will of God, for the will of God will never lead us where His grace can’t provide for us. Unbelief asks, “How can I get out of this,” while faith asks, “What can I get out of this?”

When Isaac faced the problem of a famine, he decided to go to Gerar, the capital city of the Philistines, and get help from Abimelech.6 Isaac and Rebekah were probably living at Beer Lahai Roi at that time (25:11), which means they traveled about seventy-five miles northeast to get to Gerar. Even after arriving in Gerar, Isaac and Rebekah may have been tempted to go south to Egypt, though God had warned them not to consider that possibility.

God permitted Isaac to remain in Philistia and promised to bless him. God had promised Abraham that his descendants would be greatly multiplied and one day would possess all those lands. Thus Isaac had a right to be there as long as God approved (12:2–3; 13:16; 15:5; 17:3–8; 22:15–18). God blessed Isaac for Abraham’s sake (25:5, 24), just as He has blessed believers today for the sake of Jesus Christ.

We can never successfully run away from trials, because God sees to it that His children learn the lessons of faith regardless of where they go. We can never grow in faith by running from difficulty, because “tribulation produces perseverance; and perseverance, character” (Rom.

5:3–4 NKJV). Like David, we may wish we had “wings like a dove” so we could “fly away and be at rest” (Ps. 55:6 NKJV), but if we did, we’d always be doves when God wants us to “mount up with wings as eagles” (Isa. 40:31).

The temptation to lie (vv. 7–11). Isaac could flee from famine, but when he put himself into a situation that offered no escape, he had to turn to deception to protect himself. Abraham committed this same sin twice, once in Egypt (Gen. 12:14–20) and once in Philistia (chap. 20). Remember, faith is living without scheming, and telling lies seems to be one of humanity’s favorite ways to escape responsibility.

Isaac was asked about the woman who was with him and, like his father Abraham before him, he said she was his sister. But when Abimelech saw Isaac caressing Rebekah, he knew she was his wife. Why did Isaac lie? Because he was afraid his pagan host would kill him in order to obtain his beautiful wife. His lie was evidence of his unbelief, for if he had claimed the covenant promise when he prayed for children (25:21), why couldn’t he claim that same covenant promise to protect himself and his wife?

The English poet John Dryden wrote, “Truth is the foundation of all knowledge and the cement of all societies.” When people don’t keep their word, the foundations of society begin to shake and things start to fall apart. Happy homes, lasting friendships, thriving businesses, stable governments, and effective churches all depend on truth for their success. The American preacher Phillips Brooks said, “Truth is always strong, no matter how weak it looks; and falsehood is always weak, no matter how strong it looks.” Truth is cement; falsehood is whitewash.

When he found himself in difficulty, Isaac was tempted to run and to lie, and we face these same temptations today. Isaac succumbed to temptation and was found out. It’s a sad day when unconverted people like Abimelech publicly expose God’s servants for telling lies. What an embarrassment to the cause of truth!

HE DUG AGAIN HIS FATHER’S WELLS (26:12–35)

Isaac inherited flocks and herds from his father, who had lived a nomadic life, but now the wealthy heir settled down and became a farmer, remaining in Gerar “a long time” (v. 8).

The blessing (vv. 12–14). Isaac and his neighbors had access to the same soil, and they depended on the same sunshine and rain, but Isaac’s harvests were greater than theirs, and his flocks and herds multiplied more abundantly. The secret? God kept His promise and blessed Isaac in all that he did (vv. 3–5). God would give a similar blessing to Jacob years later (chap. 31).

But Isaac was a deceiver! How could the Lord bless somebody who claimed to be a believer and yet deliberately lied to his unbelieving neighbors? Because God is always faithful to His covenant and keeps His promises (2 Tim. 2:11–13), and the only condition God attached to His promise of blessing was that Isaac remain in the land and not go to Egypt.

God also blessed Isaac because of Abraham’s life and faith (Gen. 26:5), just as He blesses us for the sake of Jesus Christ. We’ll never know until we get to heaven how many of our blessings have been “dividends” from the spiritual investments made by godly friends and family who have gone before.

The conflict (vv. 14–17). In spite of his material blessings, Isaac still suffered because of his lie, because the blessings he received brought burdens and battles to his life. Seeing his great wealth, the Philistines envied him and decided he was a threat to their safety. (A similar

situation would occur when the Jews multiplied in Egypt. See Ex. 1:8ff.)

“The blessing of the LORD makes one rich, and He adds no sorrow with it” (Prov. 10:22 NKJV). Had Isaac not lied about his wife, God would not have disciplined him but would have given him peace with his neighbors (Prov. 16:7). Because of his sin, however, Isaac’s material blessings

caused him trouble.

The Philistines tried to get Isaac to leave their land and settle elsewhere, and to encourage this they stopped up Abraham’s wells and deprived Isaac’s flocks and herds of the water they desperately needed. Water was a precious commodity in the Near East, and adequate wells were necessary if you were to succeed in the land. The crisis came when the king commanded Isaac to move away, and Isaac obeyed.

The search (vv. 18–22). No matter where Isaac journeyed, the enemy followed him and confiscated his father’s wells and also the new wells that Isaac’s servants dug. To find a well of “springing water” (v. 19) was a special blessing, for it guaranteed fresh water at all times, but the Philistines took that well, too. The names of the new wells that Isaac’s men dug reveal the

problems that he had with his neighbors, for Esek means “contention,” and Sitnah means “hatred.” But Rehoboth means “enlargement” because Isaac finally found a place where he was left alone and had room enough for his camp and his flocks and herds.

Whenever Abraham had a problem with people, he boldly confronted them and got the matter settled, whether it was his nephew Lot (13:5–18), the invading kings (chap. 14), Hagar and Ishmael (21:9ff.), or the Philistines (vv. 22ff.). But Isaac was a retiring man who wanted to avoid confrontation. Since he was a pilgrim, he could move his camp and be a peacemaker.

In every difficult situation of life, we must use discernment to know whether God wants us to be confronters like Abraham or peacemakers like Isaac, for God can bless and use both approaches. “If it is possible, as much as depends on you, live peaceably with all men” (Rom. 12:18 NKJV). Sometimes it isn’t possible, but at least we should try, and we must depend on the wisdom from above that is “pure” and “peaceable” (James 3:17).

Looking at Isaac’s experience from a spiritual point of view, we can learn an important lesson. In the Bible, wells sometimes symbolize blessings from the hand of the Lord (Gen. 16:14; 21:19; 49:22; Ex. 15:27; Num. 21:16–18; Prov. 5:15; 16:22; 18:4; Song 4:15; Isa. 12:3; John 4:14).9 The church keeps looking for something new, when all we need is to dig again the old wells of spiritual life that God’s people have depended on from the beginning—the Word of God, prayer, worship, faith, the power of the Spirit, sacrifice, and service—wells that we’ve allowed the enemy to fill up. Whenever there’s been a revival of spiritual power in the history of the church, it’s been because somebody has dug again the old wells so that God’s life-giving Spirit can be free to work.

The assurance (vv. 23–25). Beersheba was a very special place for Isaac, because there his father had entered into a covenant with the Philistine leaders (21:22ff.). Beersheba means “the well of the oath.” The Lord comes to us with His assuring Word just when we need encouragement (Acts 18:9–11; 23:11; 27:23–24; 2 Tim. 2:19). No matter who is against us, God is with us and for us (Gen. 28:15; 31:3; Rom. 8:31–39), and there’s no need for us to be afraid. In response to God’s gracious word of promise, Isaac built an altar and worshipped the Lord. He was ready to meet his adversaries.

Like his father Abraham, Isaac was identified by his tent and altar (Gen. 26:25; see also 12:7–8; 13:3–4, 18). Isaac was wealthy enough to be able to build himself a fine house, but his tent identified him as a pilgrim and stranger in the land (Heb. 11:8–10, 13–16). A fugitive is fleeing from home; a vagabond has no home; a stranger is away from home; but a pilgrim is heading home. The tent identified Isaac as a pilgrim, and the altar announced that he worshipped Jehovah and was heading to the heavenly kingdom.

Like Isaac, all who have trusted Jesus Christ are strangers in this world and pilgrims heading for a better world (1 Peter 1:1; 2:11). The body we live in is our tent; one day it will be taken down and we’ll go to the heavenly city (2 Cor. 5:1–8). Life here is brief and temporary, because this tent is fragile, but our glorified body will be ours for eternity (Phil. 3:20–21; 1 John 3:1–3). While we’re here on earth, let’s be sure we build the altar and give our witness that Jesus Christ is the Savior of the world.

The agreement (vv. 26–33). Isaac’s strategy paid off, because the Philistine leaders came to him to settle the matter of the property rights (21:22ff.). Fortified by God’s promises, Isaac was much bolder in his approach, and he confronted the Philistines with their misdeeds. It’s worth noting that Isaac’s conduct during this conflict made a great impression on them, and they could tell that the Lord was richly blessing him. More important than possessing his wells was the privilege Isaac had of sharing his witness with his pagan neighbors. (For a contrasting situation, see 1 Cor. 6:1–8.)

Isaac and the leaders were able to reach an agreement. To seal the treaty, Isaac hosted a feast, for in that culture, to eat with others was to forge strong links of friendship and mutual support. That same day, Isaac’s servants found one of Abraham’s wells (Gen. 21:25–31) and opened it, and Isaac gave it the original name, Beersheba. “The well of the oath” now referred to Isaac’s treaty as well as Abraham’s.

More conflict (vv. 34–35). Isaac was at peace with his neighbors, but he had war at home. His worldly son Esau had married two heathen wives who caused grief to Isaac and Rebekah. (Later, just to provoke his parents, he married a third heathen wife. See 28:8–9.) In view of Esau’s sinful lifestyle, we wonder that Isaac wanted to give him the patriarchal blessing (chap. 27).

All of us would like to find our Rehoboth (enlargement) where we have plenty of room and no contention, but Isaac’s Rehoboth was found only after he endured conflict. It’s through difficulties that God enlarges us for the larger places He prepares for us. “Thou hast enlarged me when I was in distress” (Ps. 4:1). When the troubles of our hearts are enlarged and we trust God, then the Lord can enlarge us (25:17) and bring us “into a large place” (18:19). If we want room, we have to suffer, because that’s the only way we can grow and feel at home in the larger place God gives us when we’re ready for it.

ABOUT THE AUTHORs:

Tom DeRosa left seminary and the church thinking he was throwing away his faith, but in reality he found a new religion: evolution. In 1978, Tom accepted Jesus Christ as Lord of his life. Soon after he studied biblical creation at Coral Ridge Presbyterian Church and came to the conclusion that a lack of knowledge of the biblical account of creation is greatly responsible for keeping many people from Christ. His commitment to breaking down those barriers is what led Tom to form Creation Studies Institute in 1988.

Carolyn Reeves, Ph.D. and her husband make their home in Oxford, Mississippi where they are active members of North Oxford Baptist Church. Carolyn retired after a 30-year career as a science teacher, finished a doctoral degree in science education, and began a new venture as a writer and an educational consultant.

ISLAND BREEZES

What can I say?  This set of books is just as great as the first two.  My grandson thinks he’s going to get these right away, but I’m not done doing projects.  I guess I’m just a kid at heart.  I’m having fun with these books.

AND NOW…THE FIRST CHAPTERs:

 

Investigation #1: Where Exactly Does Energy Go?

Think about this. Ella understands that light is a form of energy, but she is having trouble with the idea that light energy cannot be created or destroyed.

“Look,” she told her aunt, who is a science teacher. “When I flip the switch and turn off the lights, I cause all the lights in the room to go away.” She demonstrated and made the room very dark.

“Now look what happens when I turn the light switch back on. The room fills with light again. Didn’t I just create and destroy the light in the room?” she asked.

“No, you certainly did not,” her aunt said. “All you did was demonstrate how energy can change from one form into another.”

Let’s look at some examples of how energy changes from one form to another in this lesson.

German-born Albert Einstein was awarded the 1921 Nobel Price in Physics. His studies of light transformation helped to base his discovery of the photoelectric effect.

The Investigative Problems:

What are examples of energy?

Can one form of energy change into another form of energy?

Gather These Things:

1.5-vold dry cell

5-inch pieces of electric wire

Small wooden boards

Assorted rubber bands (different thicknesses, but same length)

1.5-volt light bulb

Sandpaper

Sturdy shoe box

Procedure & Observations

Electric energy ito light and head energy: Take a 1-5-volt dry cell, a five-inch wire, and a light bulb. Test different combinations until you get the light bulb to come on. Show your teacher when you are successful. Make a drawing to show how you connected everything.

Feel the light bulb. Can you tell if it has gotten any warmer? (Note: This is a small amount of head and it may not be easy to detect.)

Mechanical energy to heat energy: Rub a piece of sandpaper quickly over a board several times. Feel the sandpaper and the board. What kind of energy is produced?

Mechanical energy to sound energy: Remove the cover from a sturdy box and cut three groves on opposite edges of the box. Now choose three rubber bands of equal length, but each with a different thickness. Stretch the rubber bands around the box, fitting each into one of the grooves. Pluck each rubber band. Observe that it is vibrating. Listen for a sound. Repeat for each rubber band. Compare the pitch made by the different rubber bands. Record your observations.

The Science Stuff

Energy is what enables matter to move or to change. Energy is found in many different forms, such as heat, light, electricity, mechanical (the energy in moving things), sound, nuclear, and chemical. One form of energy can be changed into another form of energy. Still, the total amount of energy never changes. This means that energy cannot be created or destroyed. These ideas are expressed in one of the most important laws in all of science – the law of conservation of energy.

These activities illustrate some of the main forms of energy. Each activity shows one form of energy being changed into another form of energy. Electrical energy changed into light and heat, mechanical energy changed into heat, and mechanical energy changed into sound.

In the first activity, when the equipment was wired together correctly, an electric circuit was completed. An electric current then moved through the dry cell, wires, and light bulb. As the electric current moved through the light bulb, electric energy changed into light energy and heat energy.

This activity illustrates another important concept about energy. It shows that energy can be transferred from one place to another. Much of the earth’s energy is transferred from the sun to the earth.

Remember the conversation between Ella and her aunt? When Ella flipped the light switch, the electric current began to move through the wires and the light bulb. Inside the light bulb, electric energy changed into light and heat energy, which is the same thing that happened in your activity with electricity. When she turned the lights off, the objects in the room absorbed the heat and light energy. (This is a small amount of energy, and you probably couldn’t detect it without some sophisticated equipment.)

When you rubbed a board with sandpaper, your motion produced mechanical energy. This motion produced friction between the sandpaper and the wood, causing the molecules to move faster. As a result, both the sandpaper and the wood became hotter. Thus, the mechanical energy of the moving sandpaper changed into heat energy.

You were also the source of motion when you plucked the tight rubber bands, causing them to vibrate. Sound is produced when a force causes something to vibrate and produce sound waves. Sound energy is carried in waves.

Making Connections

Another way in which mechanical energy can produce sound waves is by tapping on a table. Tapping on the table causes the table to vibrate in the same way plucking on the rubber bands caused them to vibrate. Sound waves actually travel faster through the table than through the air. You can put your ear next to the table and hear the tapping sounds clearly. You can also raise your head and hear the sounds as the sound waves pass through the table and then through the air.

When electrical energy passes through a light bulb, it is changed into light energy and heat energy. Even though the heat energy is unwanted, it is still part of the electric bill. Engineers try to design light bulbs that increase the amount of light and decrease the amount of heat produced. Some progress has been made, but light bulbs continue to produce unwanted heat.

Dig Deeper

Start with the energy being given off from a TV or a radio in your home. Try to figure out where this energy comes from. See how far back you can trace the energy changes. This gets a little complicated, so get ad good reference book to help you.

What is the difference between an electric motor and an electric generator? They basically contain the same parts and are built the same way. However, an electric motor changes electric energy into mechanical energy, and an electric generator changes mechanical energy into electric energy.

In 1905, Albert Einstein proposed a theory that altered the law of conservation of energy. He said that matter can be changed into energy, and energy can be changed into matter, but the total amount of matter and energy in the universe remains the same. How was Einstein’s theory shown to be true?

What Did You Learn?

Give two examples of how one form of energy can change into heat energy. Give another example of an energy change.

List two ways in which energy does work for us.

The following list contains examples of forces, properties of matter, and forms of energy. Underline all the examples of forms of energy: inertia, heat, density, buoyancy, electricity, lift, weight, chemical, push, and nuclear.

Define mechanical energy and give an example.

What kind of energy can be quickly provided by a battery?

What is the law of conservation of energy?

Give an example of when an unwanted form of energy is produced in a device.

What happens to a roomful of light on a dark night with the lights are turned off?

Was energy transferred from the batter to the light bulb when an electric circuit was completed?

ISLAND BREEZES

Chick lit with a twist.  It’s written by a guy, but so good you forget the gender of the author.  It wasn’t until the end of the book that I remembered the author was not a female. He is so good at getting inside the head of Harper and the other female characters.

Harper was at the end of her rope when she was rescued.  Then a series of unlikely events turned her life upside down.  She wants to act, but she’s only an understudy.  She wants love and her nearest connection is via the Internet and on the other side of the country.

This book is filled with ups and downs.  Sometimes it seems like a lot of downs.  How do Harper and her friend, Avril, handle the curve balls?  Will this life’s play have a happy ending or just another intermission?

Don’t forget to check out the afterwards section and let Chris know which character you would like to see in a sequel. 

AND NOW…THE FIRST CHAPTER:

I absolutely had to be in New York by 1:30 p.m. Did my life depend upon it? Yes, as a matter of fact, it did. Just the thought of calling Ben or Avril with bad news from O’Hare churned my stomach and made my face prickle with a dizzying fear. I joined a sea of travelers bundled in parkas, hoods, hats, and gloves; they stretched out in front of me, pressing in and wresting me through a queue of red velvet theater ropes.

All of Chicago wanted to flee the blizzard they’d awakened to. Sometime after midnight the sky exploded with snowflakes. Icy white parachutists fell from their celestial perch as innocently as doves. The year’s last snowstorm tucked the city in with a white blanket knitted through the long winter’s night.

When I reached the American Airlines check-in, I hoisted one of my two black canvas bags onto the scale for the ticket agent.

“Harper Gray?” she asked, confirming my reservation.

“Yes.”

She returned my driver’s license, dropping her gaze to the workstation and tapping my information into the system. At the kiosk next to me, a large Texan with a silver rodeo buckle typed on his iPhone with his thumbs, mumbling something about checking the weather in Dallas.

Computers, I thought. What don’t we use them for?

It was obvious how many of my fellow travelers were heading somewhere for the New Year’s Eve festivities. I couldn’t help but eavesdrop on a cluster of merry college students reveling in their Christmas

break. They joked and chattered, mentioning Times Square, unbothered by long lines or the imminent threat of weather delays. At thirty, almost thirty-one, I could no longer relate to their carefree lifestyle. Too much water under the bridge, most of it dark and all of it numbing.

“Here you are,” the ticket agent said, handing me a boarding pass still warm from the printer. I fumbled with my things, stuffing my photo ID into my wallet as a mother and her young son squeezed in next to me. The crowd current swept me away from the ticket counter, denying me a chance to ask the agent the one question I most wanted answered.

Is anyone flying out of here this morning?

I rolled my carry-on through the main concourse. I’d used the small black Samsonite for so many trips, I thought the airlines should paste labels on it like an old vaudevillian’s steamer trunk. A row of display monitors hung from a galvanized pipe, cobalt blue icicles glowing all the brighter in the dark and windowless hallway. I joined a beleaguered crowd of gawkers studying the departure screens. Their collective moans of frustration confirmed what I already knew. My flight—indeed, all flights out of O’Hare—was:

DELAYED

I pinched my eyes shut. This was not what I needed. Not today, not today of all days. I absolutely had to be in New York by 1:30 p.m. Did my life depend upon it? Yes, as a matter of fact, it did.

Resh – Keeping God’s Law in Adversity

January 17th, 2010

Look on my misery and rescue me, for I do not forget your law.  

Plead my cause and redeem me; give me life according to your promise.

Salvation is far from the wicked , for they do not seek your statues.

Great is your mercy, O Lord; give me life according to your justice.

Many are my persecutors and my adversaries, yet I do not swerve from your decrees.

I look at the faithless with distrust, because they do not keep your commands.

Consider how I love your precepts; preserve my life according to your steadfast love.

The sum of your word is truth; and every one of your righteous ordinances endures forever.

Psalm 119:153-160

ISLAND BREEZES

This is another great book combination with the same format as the books reviewed yesterday.  Today it is about elementary chemistry. 

I’ve always loved chemistry, so guess who is learning and playing through this book.  That’s right.  Granny Nanny.  The grandson is going to have to wait for this set of books as well.

Matter

Its Properties & Its Changes

By Tom DeRosa & Carolyn Reeves

Investigation #1: The Physical Side of Chemicals

Think about this. A detective collected samples of food from the table where a victim was eating when he collapsed. The detective sent them to a crime lab. A few days later, the lab called to say they had positively identified a poison in the victim’s food that was not in anyone else’s food. Have you ever wondered how someone in the crime lab could figure out what chemicals are present in food or in someone’s blood or in something else?

The Investigative Problems:

How can the physical properties of a chemical substance be used to help identify the substance?

Gather These Things:

Magnet
Iron nail
Sugar cube
Copper penny
Container of water
A piece of paraffin
Small amount of vegetable oil

Procedure & Observations

Your teacher will show you ten items. Your job is to identify one of the items on the basis of its physical properties. You should eliminate any item that doesn’t match the descriptions. These are the physical properties of the item: It is round. It is flat. You would not want to eat it. It would be hard to break. It is shiny. What is the item that has all of these properties?

Your teacher will give you some more substances to investigate, but each of these will be a pure chemical substance. They will be either an element or a compound.

Bring a magnet near each substance and observe if the magnet has an effect on it. Place each substance in a container of water and observe if it floats or sinks. Note if it is soluble (will dissolve) or insoluble (will not dissolve) in the water. Note also the color and whether it is shiny or dull. Put this information in a data table.

(sample of date table)

The Science Stuff

Physical properties are often characteristics you can see, hear, taste, smell, or feel, but may include any physical characteristics of a substance. You used some simple physical characteristics to identify one of the ten items you were first shown.

Some of the items you were shown were pure substances (like the glass), and some were a mixture of many substances (like the apple). A pure chemical substance could be either an element or a compound. (We’ll learn more about elements and compounds later.) A fragment of a pure substance would have the same properties as the whole substance. All of the basic particles in a pure substance are the same. For example, a piece of pure iron only contains particles of iron and a container of pure water only contains particles of water.

Properties such as size and shape were helpful in identifying the first items, but they are seldom considered in identifying pure chemical substances. The properties of the five pure substances listed in the chart will be present regardless of the size, shape, or amount of the substance. Scientists look for characteristics that will remain the same no matter where the chemical is found. Almost any substance can be made into a round shape, so this would not be helpful in knowing what chemical is present.

We examined physical properties of several pure substances, including the effects of a magnet, whether the substance would float or sink in water, whether the substance was soluble or insoluble in water, its color, and its shininess. There are many other properties we could have considered, such as odor, taste, density, hardness, brittleness, elasticity, melting and boiling temperatures, solubility in other liquids, conductivity of heat and electricity, and viscosity.

Making Connections

There is a huge need for methods, instruments, and trained people to identify chemical substances that are present in things. Identifying unknown chemicals is part of the study of analytical chemistry. This includes what chemical are present, their characteristics, and how much is present. There are many crime labs that hire people to help solve crimes by identifying things such as drugs, alcohol, poisons, or traces of gunpowder. Medical labs test blood and urine for the presence of many kinds of substances. Other labs help identify pollutants in the air, water, and environment. Industries must consistently monitor their products for impurities. These are only a few of the places where chemicals are analyzed.

One of the most important things any society can do is to maintain a clean source of water. During the Industrial Revolution, many factories were built next to a river so they could dump their wastes into the river. Congress eventually passed a number of laws to try and keep our water sources free of pollution. Even today, environmentalists look for better ways to prevent pesticides and other harmful chemicals from being washed into rivers and lakes after a rain.

Dig Deeper

Labs generally use both traditional methods and a variety of instruments to identify chemical substances. An instrument known as a spectroscope is often used to help analyze the chemicals in something. Do some reading about spectroscopes to find out how they work and what uses thy have.

Crime labs hire forensic scientists. What do forensic scientists do? Is there more than one kind of forensic scientist? If so, what are the different areas in which they work?

What are some of the U.S. laws that try to prevent water pollution? Do all countries have similar laws? Try to find the name of one charity whose mission is to provide clean water to people who don’t have clean water to drink.

ISLAND BREEZES

This is fun and informative.  Each chapter or “investigation” gives you a little something to think about, a question or two to investigate, a little project and the science behind the project.  From there you have things to think about and a summary of what you learned. 

The format makes it easy and fun to learn about physical science.  The student journal and teacher’s guide make it an unbeatable combination.  If you’re homeschooling an elementary child, you can’t lose with this. 

These books make me wish I had a kid at home.  My grandson will be the beneficiary, but not until his Granny Nanny spends a little more time with the fun projects.  I’m learning, too. 

AND NOW…THE FIRST CHAPTER:

Forces & Motion

From High-speed Jets to Wind-up Toys

By Tom DeRosa & Carolyn Reeves

Investigation #1: Wind-up Walking Toys, Speed, Time, and Distance

Think about this. Many people still consider “Bullet” Bob Hayes to be the world’s fastest runner. In the 1964 Tokyo Olympics, he was part of a 4 X 100 relay race. He was already running when he took the baton. He completed his 100 meters of the relay in 8.6 seconds. He also ran the 100-meter dash in 10.05 seconds. In this race, he started from a still position. Four years later at the Mexico City Olympics, James Hines ran an official time in the 100-meter dash that was less than 10.0 seconds for the first time ever. His record stood for several more years, but Bullet Bob’s relay race time will be a hard record to break.

These very fast runners were moving an average of about ten meters every second. Use a meter stick to mark off ten meters and make a prediction of how many meters you think you could run each second. Would you like to be able to figure out how many meters you can run in one second?

We can calculate the speed of a moving object by testing wind-up toys. How far a wind-up toy moves can be measured with a ruler. How long it takes the toy to move a certain distance can be measured with a watch. These two numbers can be used to calculate its speed.

The Investigative Problems:

How can we determine the speed and motion of a wind-up talking toy?
How can this be shown on a graph?

Gather These Things:

Walking toy
Chart
Pencil
Clock with second hand
Toothpicks
Metric ruler (with each cm divided into tenths)

Procedure & Observations

For these measurements, you will need a metric ruler where each centimeter is divided into tenths. Look carefully at the markings on the ruler. Notice there is a long line by each number. There are shorter lines following each number. The short lines are written as decimal numbers. Measure the line to the right by putting the zero mark of the ruler at the beginning of the line. The correct answer is found by writing the last whole number, a decimal, and the number of short marks following the number. The abbreviation “cm” is written after these numbers. Did you get 15.3 cm for your answer? Work with a partner. Each of you should draw two or three more lines. Measure each other’s lines. Check each other’s answers.
Lay the ruler out in front of you. Wind up the walking toy next to the ruler and measure how far it walks in ten seconds. Record. Calculate its average speed by dividing the total distance it walked in centimeters by ten seconds. Write your number answer followed by cm/s. This is read “centimeters per second.”
Measure how long it takes for the wind-up toy to walk one meter. Record. If it doesn’t make it that far, record how far it walked and the time it walked. Calculate its average speed by dividing the distance it walked by the time. The speed will be in m/s (meters per second) if it walks as far as a meter. If you measure the distance in cm, your answer will be in cm/s.
Go back to the starting point. Wind up the toy again. This time lay down a toothpick next to the ruler every time the instructor calls out a five-second interval. Record for 30 seconds. Measure the distances between toothpicks and record in the chart below.
Graph the results of distance versus time. Your teacher will show you how to put this information in the graph. Does your graph make a straight line or a curved line? Try to think of a reason for this.
Did your walking toy start out fast and then get slower until it stopped, or did it keep walking at the same speed all the way?
Race your walking toy with someone else’s. Which one was the fastest?

The Science Stuff

The motion of an object can be described by changes in its position, by its direction, and by its speed. Speed can be calculated by measuring the distance an object moves and the time it takes to move that distance. Divide the distance by the time to get the speed.

The distance traveled equals the object’s speed multiplied by the time traveled. The same units of time must be used. For example, if a toy travels 50 cm/minute and it travels fro a total of two minutes, it has traveled a total of 100 cm. The calculations would be 50 cm/min X 2 min = 100 cm. Minutes would cancel out, leaving cm as part of your answer.

Different aspects of motion can be shown on a graph. If the speed of the walking toy stayed the same, the graph line will be straight, but if your walking toy slowed down, the graph line will be a curve. Remember, the source of energy for walking toys is a wind-up spring. A tight spring may provide more energy than a loose spring.

Scientific measurements are taking in metric units. The correct abbreviation for centimeter is cm; for meter, it is m. the correct abbreviation for centimeters per second is

Cm/s; for meters per second, m/s.

1 centimeter (cm) = 1/100 meter
1 meter (m) = 100 centimeters
1 kilometer (km) = 1000 meters

Dig Deeper

See if you can use the Internet or some reference books to find the runners who have run at official speeds of ten meters per second or greater. (There won’t be many.)

Do additional research to find some more world records for swimming, skating, bicycling, or other sports.

Use the Internet or some reference books to find the top speeds of several animals. Did you find any that you could outrun? What is the difference in how humans run and how certain animals run.

(If you choose one of these projects, use a creative way to display your findings.)

Making Connections

Sometimes a highway patrol officer will stop a car for speeding, and the driver will insist that the car was traveling within the speed limit. Is it possible that the car’s speedometer is not accurate? Mile markers along the highway and a watch can tell if your car’s speedometer is accurate. To do that, have the driver hold the car’s speed at 60 miles/hour. Start timing with a watch that has a second hand as the car reaches a mile marker. Stop timing as the car reaches the next mile marker. The speedometer is accurate if the car travels one mile in 60 seconds. One mile/minute is the same as 60 miles/hour. You can also calculate the speed of your car by dividing the distance of one mile by the time it takes the car to travel from one mile marker to another.

Suppose you are traveling in a car wit the cruise control set at 65 miles per hour and your driver drives for two hours without stopping. Multiply the speed by two hours to see how many miles you have traveled in two hours, as: 65 mi/hr X 2 hr = 130 miles.

What Did You Learn?
