Explore the three states of matter and how materials can change between them.

Materials can be solids (like ice, which keeps its shape), liquids (like water, which takes the shape of its container) or gases (like steam, which spreads out to fill a space).
Heating and cooling can change a material's state — for example, ice melts into water when heated, and water evaporates into water vapour (a gas) when heated further. We look at everyday examples of these changes.
