I thought that maybe I should list some alternatives for the impossible object lesson. These are designed to go with the Sunday School lesson on Israelites crossing the Red Sea.
For some, the ice trick might be a little scary. It seems too impossible to work, doesn’t it? Well, here is the science concept behind the idea:
If you are afraid to try the actual experiment yourself, you could just play this YouTube video. The problem is that of course this person never explains how this relates to the Israelites crossing the Red Sea. So, of course you will need to add that part in yourself.
Here’s another idea. Eggs in salt water will float. But, eggs in fresh water will not float. It would be fun to let one or more of the students try to make an egg float in a glass of water. Make sure they try enough times so that the entire class agrees it is impossible to make an egg float in water. Then, use your own glass of salt water to make an egg float. Use this to talk about how God did what seemed impossible to the Israelites when he moved the water of the Red Sea so they could cross.
Here’s one more impossible object lesson you could use. Everyone knows you can’t stick something sharp in a balloon without it popping, right?
And, finally, make things float in the air without you touching them.
These great ideas should give you some options if the ice trick is a little too scary for you to attempt. Also, remember that you could always show the actual YouTube video, if you really aren’t comfortable with doing it yourself. Personally, I’m a little afraid that all the chatter in the video will distract from the meaning, but you should make your own decisions for your classroom.
Let me know what you think. Do you know of any other “impossible” object lessons?
