Co-op

Last month, my friend Jan taught a Science class at our homeschool co-op. The class was about surface tension and she had the kids do several different experiments to help them learn about this scientific principle.

First, the kids had to see if they could make a paper clip float on water. It's not as easy as you'd think. Then they sprinkled pepper in their bowls of water, dipped toothpicks in oil and put the toothpick in the pepper. They were all amazed as the surface tension broke and the pepper spread to the edge of their bowls. After that, they experimented by dropping food coloring into a bowl of milk and watching the designs it made. This was pretty neat. Their last experiment was putting drops of water onto a penny...can you guess how many drops of water you can get on a penny before it splashes off? This penny has 46 drops of water on it...no joke! This was one of those great classes that everyone got into... Even the moms!
Thanks, Jan, for a GREAT science class!
