In this activity, students watch a short PowerPoint presentation explaining what precipitation is and how clouds form.

By the end of this activity, students should be able to:

  • explain what precipitation is and how water vapour is transported and concentrated in the atmosphere
  • describe how water appears as different phases in the air – vapour, droplets and ice particles
  • explain that clouds are mixtures of droplets and ice particles and that this mixture changes with temperature.
