Lesson details

Key learning points

  1. A substance may have a solid, liquid and gas state
  2. In the solid state a substance has a fixed shape, it does not flow and cannot be compressed
  3. In the liquid state a substance can flow, it fills the shape of its container and cannot be compressed
  4. All substances are made of particles that are too small to see

Common misconception

Students think that the particles are embedded in the substance

Ensure that students are reminded that all matter is made of small particles and nothing is between the particles.

Keywords

  • Solid state - the substance has a fixed shape and cannot be compressed

  • Liquid state - the substance can flow, it fills the shape of its container and cannot be compressed

  • Gas state - the substance does not have a fixed shape and will take the shape of its container

  • Flow - when a substance can be poured from one place to another

  • Compress - when a substance is made to take up less space (volume)

When drawing particle models of solid state, liquid state and gas state, students should not draw the particles too small it should be clear if the arrangement is random or regular. Students should show touching particles in a liquid state.
