Water has unusual properties that make it different to other liquids. It is the only common substance that is naturally found as a solid (ice), liquid (water) or gas (water vapour). Water has the greatest surface tension of any common liquid. It is also able to dissolve many substances. These unusual properties make water an ideal topic for students studying the Material World at NZC levels 1 and 2.

Overarching learning outcomes of this teacher resource integrate:

  • an introduction to the characteristics of solids, liquids and gases (scientific knowledge)
  • investigations into states of matter and surface tension (science practice)
  • opportunities for students to investigate and communicate as scientists (nature of science)

Students will meet these learning outcomes by:

  • the use of hands-on investigations and drama to learn about the particle nature of water as a solid, liquid or gas
  • recognising that heat (energy) is necessary for changing states of matter
  • exploring surface tension via soap bubbles and other simple activities.
