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.
