Topics

• Atoms
• Molecules
• States of Matter

Description

Heat, cool and compress atoms and molecules and watch as they change between solid, liquid and gas phases.

Sample Learning Goals

• Describe characteristics of three states of matter: solid, liquid and gas.
• Predict how varying the temperature or pressure changes the behavior of particles.
• Compare particles in the three different phases.
• Explain freezing and melting with molecular level detail.
• Recognize that different substances have different properties, including melting, freezing and boiling temperatures.

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
