Egg Experiment

fresh water
raw egg


We put a raw egg in the shell into fresh water and it sunk. Then we added salt to the water. At first nothing happened. So we added more salt. And more salt. Then it started to float up! The salt made the water denser than the egg!

Later we put in food coloring and vinegar and oil just for fun.

Freezing Experiement



One day me and my mom did a freeze water in a jar experiment. Water unlike most liquids expands when freezing. Ice is very strong and I can tell that because when we got it out of the freezer the jar was broken! The ice was not.
