Please write everything that is underlined:

Everything around us that takes up space and has mass is known as matter. This includes the chair you're sitting on, the milk you pour on your cereal and the air you breathe.

Matter includes solids, liquids and gases. These different forms of a substance are called states of matter.

For example, water can be found in all three states on Earth. Ice is water in its solid state. When water is a gas, it's called water vapour.

​Someone please read out loud

You probably see solid water and liquid water every day. But water vapour is an invisible gas, so you can't see it. It's actually all around you, mixed in with the other gases that make up air.

Clouds form when water changes from a gas to a liquid. When the invisible water vapour in air cools down, it forms droplets of liquid water. These droplets are so tiny that they can float in air. Some clouds are so cold that they are made up of solid ice crystals.

Multiple Select

Clouds are made up of water that we can see.
