Activity Description:

Select samples from an outdoor setting. Magnify the substances to atomic level so that the particles they consist of can be seen. Sort the substances into groups based on how the particles are arranged and how they move. Classify the substances as solids, liquids or gases. For example, classify argon as a gas and ice as a solid. This learning object is the second in a series of six objects that progressively increase in difficulty.

This interactive learning activity is aligned with Solomon Islands Year Seven Science Curriculum:

• Strand: Natural and Processed Materials
• Sub-strand: 7.3 Solids, Liquids, and Gases
• General Learning Outcome:
  • 7.3.2 understand the different states of matter (u)
  • 7.3.3 be able to investigate physical changes (s)
• Specific Learning Outcome:
  • 7.3.2.1 use the idea of particle movement to explain the difference between the three states of matter: solids, liquids and gases
  • 7.3.3.1 investigate and explain the changes caused by heating and cooling of solids, liquids, and gases
