This set of four posters will help your students to learn what happens to particles when substances are heated or cooled.

The posters include particle diagrams of solids, liquids and gases. They are accompanied by descriptions about how the particles move and change arrangement during heating and cooling.

You can print the posters on A4 paper. Alternatively, you might like to enlarge them to A3 or reduce them to A5 size.
