States of Matter

During this programme of study, pupils will:

  • compare and group materials together, according to whether they are solids, liquids or gases
  • observe that some materials change state when they are heated or cooled, and measure or research the temperature at which this happens in degrees Celsius (°C)
  • identify the part played by evaporation and condensation in the water cycle and associate the rate of evaporation with temperature

Becoming experts in States of Matter, children will develop and showcase an understanding of all areas of states of matter, including how materials can change from one state to another, through a large range of simple, practical enquiries. 

  • Examining and comparing the properties of sand and water, children will Investigate the differences between solids and liquids.
  • After completing a series of practical activities to learn more about gasses, children will learn about how particles behave in different states and use a thermometer to make observations as water changes from one state to another. 
  • Learning about the water cycle, children will begin to understand the terms evaporation and condensation and that water moves in a cycle due to changes in temperature, causing the water to change from one state to another.
