I went over to Desert Boy's school the other day and we talked about how birds make different kinds of nests. The kids made their own nests, which varied from a hole in the ground to some grass on branches, to a big platform of sticks. Then we had time to talk about what goes in the nests--the eggs. I had the kids inspect the shape of the egg, and we talked about how arches are one of the strongest shapes and how an egg incorporates arches. To make sure they remembered that eggs are strong, I then had them stand on a fresh eggs. They didn't want to do it at first, but they were all quite excited once they saw it worked.
Every kid in the class stood on the eggs, and none of them broke, much to their amazement.
We had one more science experiment: try to crack a raw egg by squeezing it as hard as you can with one had.
We actually did have one egg break open (good thing we were outside!). I think it probably had tiny cracks in it before we started. Or maybe Ava really is the strongest one in the school!
So if you have extra eggs lying around, give it a try! There's a tiny bit of fear as you wonder if you will have a big mess to clean up, but most likely you won't.
Happy Earth Day!
