Solids and Liquids
In your ice experiment, you watched ice cubes turn into puddles of water. But what actually happened? The ice changed from a solid to a liquid!
A solid is something that holds its shape. You can pick it up and it does not flow or change shape. Ice cubes, rocks, books, and toys are all solids.
A liquid is something that flows and takes the shape of whatever container it is in. Water, juice, milk, and honey are all liquids. If you pour water into a cup, it takes the shape of the cup. If you pour it into a bowl, it takes the shape of the bowl.
Here is the cool part: ice and water are the same thing! They are both made of water. The only difference is temperature. When water gets very cold, it freezes into solid ice. When ice gets warm enough, it melts into liquid water.
