Many science experiments produce dramatic, attention-grabbing results that fascinate kids of any age. The simplest objects can become a scientific demonstration of biblical messages you want to communicate to your child. Bible science object lessons focus your kids' attention on a concrete representation of an abstract scriptural concept for a memorable lesson in Biblical truth.
A Bible science object lesson can demonstrate how invisible forces can chase away sin and evil. Put some salt and pepper on a paper plate. Rub a plastic spoon on wool to electrify it and pass it over the salt heap. The pepper will jump onto the spoon. Alternately, sprinkle pepper into a bowl of standing water. A drop of dish soap into the pepper field breaks the water tension and scatters the pepper. In either version, the pepper represents the evil that tempts your child to disobey God. The static electricity or dish soap is God’s protecting or cleansing power to remove sin and evil influences in your child’s life.
The Joy of the Lord
Jesus told His followers in John 15:11, "I have told you these things that … your joy and gladness may be… complete and overflowing." Pour a few cups of water into a clear container while talking about letting God fill your child's heart through prayer, Bible reading and fellowship. Let your child taste a dab of vinegar and pronounce it "yucky." Pour the vinegar into the water and explain that even though believing in Jesus doesn’t stop bad things from happening, God can still inspire overflowing joy. Add a few teaspoons of baking soda to represent the Holy Spirit and watch as all the "goodness" that you poured in erupts out, overflowing its container.
By Grace, Not Works
Ephesians 2:8 instructs Christians that they are saved by God’s grace “not as a result of works, so that no one may boast.” To demonstrate that your child cannot earn her way to heaven with good deeds, you need a white cloth, two clear containers, water, cornstarch, iodine and liquid bleach. In advance, boil one cup of water and half a teaspoon cornstarch and let it cool. Thoroughly wet the cloth in this solution, air dry and iron it. Pour one cup of warm water into each clear container. Add 2 teaspoons of the starch solution to the first jar and ½ cup liquid bleach to the second. Stain the cloth with iodine while explaining to your child that when she is naughty, she stains her heart with sin. Dip the cloth in the starch jar and explain that even being extra good, obedient and helpful does not take the stain away. Soak the cloth in the second jar until the stain is gone to show how only Jesus can clean the stain of sin.
Growing in Faith
Several Bible passages talk about abundance or rapid increase of a Christian's gifts or God's never-ending goodness and love toward His people. You can illustrate how this abundance expands as your child grows in his faith with an insta-snow science demonstration. Pour a whole box of Instant Snow Powder into a large, wide-mouth container. Point out that nothing happens if you just leave the powder alone, just as you don't grow closer to God without effort. Have your child pour in several cups of water to care for his "seeds." The powder absorbs the water and expands exponentially for a visually effective illustration of the abundance of love, grace, mercy, forgiveness and blessing God pours out on those who believe in Him. In turn, then, your child can pass the same onto others around Him to help them grow in faith as well.
