2:5

Earth is full of solids, liquids, and gases. When it rains, water drops fall from the sky. The water drops are a liquid. When the water freezes it turns into ice. The ice is a solid. When the ice melts and dries up. It goes back into the sky as water vapor. This water vapor is a gas.

Can you think of some things that we find on Earth that are water in the form of a solid, a liquid and a gas?
