floating eggs

Materials you will need: • Table Salt • Two Bowls • A Tablespoon • Warm Tap Water • Two Eggs • A Friend

Steps:

1. Fill both bowls with warm tap water.
2. Add a few tablespoons of salt to one of the bowls of water and stir it really well, until the salt has dissolved in the water.
3. Carefully place a egg in each bowl.
4. One egg will float and the other will sink. 

Which egg floats?  _____________.   Do you know why?

The salt water is heavier than the plain tap water, so the weight of the egg does not have to push away as much water to make space for itself and therefore it floats.
