While discussing the differences between saltwater and freshwater with my boys, I thought it would be a great opportunity to introduce to them the floating vs. sinking egg experiment! We started out with two clear cups and filled them both with warm water. In one of the cups we put around 10 tablespoons of salt. After that we placed one raw egg into each of the cups and observed. Since saltwater is denser (heavier) than freshwater the egg floated instead of sinking like it did in the freshwater.
This experiment will also work on a number of other things! We tried baby carrots and grape tomatoes and received the same results.
