This activity addresses the following Solomon Islands Year 7 Science Learning Outcomes for Unit 7.3: Solids, Liquids, and Gases

• 7.3.2 understand the different states of matter (u)
  • 7.3.2.1 use the idea of particle movement to explain the difference between the three states of matter: solids, liquids and gases
• 7.3.3 be able to investigate physical changes (s)
  • 7.3.3.1 investigate and explain the changes caused by heating
    and cooling of solids, liquids, and gases
    7.3.3.2 draw a simple particle diagram to show the change of
    state from one form to another
• 7.3.4 be able to show that in a physical change the mass of the substance remains the same, only particles rearranged (s)
  • 7.3.4.1 conduct an experiment to observe that in a physical change the properties of the materials change, but the mass remains unchanged: melting of ice cubes
