Changing state

This week Year 6 have turned into scientists, and have been investigating Solids, Liquids and Gases. They found out that everything is made up of tiny particles, which move around in different ways. The children used their bodies to demonstrate what the particles were doing in a solid, liquid and gas.

I wonder if you can guess which photo shows:  a solid – where the particles are packed tightly together in a regular pattern, a liquid – where the particles are touching but have gaps in between them which allow more movement, and a gas – where the particles are randomly spread and fill the space.

The children also conducted a scientific experiment, to see what affected the speed an ice lolly would melt.
