Science Experiment - Popping the Cork!

This Experiment can be found in the first Science and the Bible book - I highly recommend them!

Theme: An uncontrolled temper is foolish and also dishonors the Lord

Bible Verses: A hot-tempered man must pay the penalty; if you rescue him, you will have to do it again (Pr 19:19)
Materials Used: bottles with corks; vinegar; baking soda;

Lesson: Uncontrolled tempers often bring improper words and actions. The result may be bad decisions and broken friendships. Usually the result is worse than the problem that caused the temper tantrum in the first place. The Bible tells us how a hot-tempered person doesn’t easily learn patience, but repeats the same error again and again. The cure to a temper problem is also found in the Bible. Proverbs 15:1 says that “A gentle answer turns away wrath, but a harsh word stirs up anger”.

Illustration: We illustrated an uncontrolled temper by seeing pressure build up inside a bottle. Pour a cup of vinegar into the bottle. Add a table spoons of baking soda (wrap in a piece of tissue to give you extra time). As the paper moistens, bubbling will start. The reaction between baking soda and vinegar produces carbon dioxide gas. Watch the cork burst out at an unpredictable time just like people’s tempers.

This is one of my favorite experiments we do each year. I usually let each child help with the experiment. They usually take put the tablespoon of baking soda on the tissue and then they quickly put the cork on right after I put the baking soda in the bottle. Last year, one of my kids turned the bottle toward his face and got a face ful of vinegar. So, this year, each child wore safety glasses when they were helping - which they seemed to think was pretty fun!

Last night was armor night - enjoy the pictures!
