Solids, Liquids and Gases for Kids: States of Matter (Kindergarten to Grade 2 Science)

Hi, I'm Luna from DoodleBeez. Everything around us is made of matter. Matter is anything that takes up space. Today we are learning the three states of matter, solid, liquid and gas.

A solid keeps its own shape. A block, a spoon and an ice cube are all solids. Put a block in a cup or in a bowl, and it stays the same shape. You can hold a solid in your hand.

A liquid flows and pours. Water, milk and juice are liquids. A liquid takes the shape of whatever it is in. Pour water into a tall glass or a round bowl, and it changes shape to fit.

A gas spreads out to fill all the space it can. Air is a gas. We usually cannot see air, but we can feel it as wind. When you blow up a balloon, air fills it right up.

Water can be all three! Freeze water and it becomes solid ice. Warm the ice and it melts back into liquid water. Heat water a lot and it boils into a gas called water vapor.

Heating can melt a solid into a liquid. Cooling can freeze a liquid into a solid. A chocolate bar melts on a hot day, and juice in the freezer turns into an icy treat.

Now it's your turn. Is a rock a solid, a liquid or a gas? What about the juice in your cup? Pause and try. The rock is a solid. It keeps its shape. The juice is a liquid. It pours.

Great job! Remember, a solid keeps its shape, a liquid takes the shape of its container, and a gas spreads out to fill the space. Practice solids, liquids and gases in the Science Lab at doodlebeez.com. See you next time!
