Key Stage 2
Investigate the different types of materials that make up our Universe. Which material takes up most of the space in a room? And what are the gases that make up the air around us?
Race bubbles to explore properties of liquids, and sort solids into different groups. Can you identify solids that are natural from those that are made?
Predict what happens to solids in severe cold — can you make a nail out of sticky tack with the help of liquid nitrogen? Can you freeze and thaw a flower? What happens when you rapidly cool air-filled balloons?
