After discussing the half-term homework about changes of state, we learnt about how particles are arranged in solids, liquids and gases.

We used the hall space to demonstrate the arrangement with our bodies.

Can you see the differences between the states?

Here are some of the investigations which Class 4 members carried out at home:

In this investigation, a solid jelly turned in to a liquid and then a solid again. It looks amazing!

This liquid water was cooled until it changed state: it is now ice.

Part of this wood was converted in to gas when it was burnt.
