Our first Science Fair

Last week Paige entered in her school's science fair.

I showed Paige a website of all different kinds of science experiments she could pick from. She liked the ones about eggs, but she wanted to do them all. They were pretty simple, but suddenly we had to do 4 different things.

Question 1: Can an egg bounce?
Of course you'd say no. But after soaking the egg in a cup of vinegar for a few days, the shell dissolves and sure enough. It makes a rubbery bouncy egg. Pretty cool.

Question 2: Can I make an egg float in water?
If you fill a glass with water and stir in a few spoonfuls of salt it will float because the density of the water changed.

Question 3: Will an egg break if something heavy sits on it?
We placed 4 large yearbooks on top of 4 eggs. The curved shape of the eggshell distributes the weight across the egg so it can support more weight.

Question 4: Can I tell if an egg is raw or cooked?
If you spin the eggs on a flat surface you can tell the difference. A hard-boiled egg spins well, but a raw egg wobbles around because the yoke inside bumps around.




























Paige had a great time explaining the different experiments. The entire fair was pretty low key, but Paige got 2nd place for the kindergartners. It was fun.
