Key Topics to Revise

1

What is Matter?

  • Matter is anything that has mass and occupies space.
  • Examples of matter: books, water, air, toys, and even we are made of matter.
  • Shadows and light are NOT matter because they do not have mass or take up space.
2

Three Forms of Matter

  • Solids have a fixed shape and size. They do not flow.
  • Liquids can flow and take the shape of their container.
  • Gases do not have a fixed shape or size. They spread out to fill the space.
3

Changing States of Matter

  • Matter can change from one form to another by heating or cooling.
  • Heating turns solid into liquid (melting), and liquid into gas (evaporation).
  • Cooling turns gas into liquid (condensation), and liquid into solid (freezing).
4

Uses of Matter

  • We use solids, liquids, and gases every day.
  • Solids: used to make furniture, toys, books, and buildings.
