Science Week - Ms Phelans 2nd / 3rd class - floating

posted Nov 18, 2020, 12:40 PM by Owen Breslin

This week we were learning all about density. We learned that objects sink in water when they are denser than the water. We decided to test this out by using an egg, salt and water. The egg sank in the water. So we added salt to the water. By adding salt, the water became denser. When the water was denser than the egg, the egg floated.
