Describe the differences between solids, liquids and gases
The three states of matter are solid, liquid and gases.
Water can exist as a solid (ice), as a liquid (water) and as a gas (water vapour).
A gas takes up space but has no definite shape.
A liquid takes up the shape of the container it is put into but its volume doesn’t change.
A solid usually has a definite shape ( even if it can be easily changed e.g. squeezing a sponge)

 

1 Examine a set of solid objects and decide which features they have in common.
2 Pour a given volume of water into a series of containers of different shape and describe what happens.
3 Discuss the nature of air, e.g. pushing an upturned jam jar into water to show that air takes up space.
4 Balance two uninflated balloons on a coat hanger, then blow one up and demonstrate that a highly inflated balloon weighs more.
