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
