Gases Around Us

I can name several gases and identify one way in which each is useful to us

I know the properties of solids, liquids and gases

I know that the process which takes place when water changes to a gas is evaporation

I can use measuring jugs or cylinders to make measurements of volume

I can repeat measurements to check results

I can explain that bubbles appear because the water pushes the air (gas) out of the spaces between the particles of soil
