3. Materials around us - Water cycle

Water cycle

How water moves between the land, sea, and clouds.

Evaporate

When a liquid changes into a gas with heat.

Condensation

When a gas changes into a liquid.

Freeze

When a liquid changes into a solid.

Melt

When a solid changes into a liquid with heat.

Liquid

Matter that fills its container and takes its shape.

Gas

Matter that is all around us, like air.

Solid

Matter that keeps its own shape.

Changes of state

When matter changes from one state (solid, liquid, gas) to another.

Earth

The planet where we live, where the water cycle happens.

Clouds

Part of the water cycle.

Ocean

Large bodies of water on Earth. Water moves from here in the water cycle.

Heating

Adding energy, makes things warmer. Causes melting or evaporation.

Cooling

Taking energy away, makes things colder. Causes freezing or condensation.

Matter

The material around us.
