Year 3

Lesson 4 • Which ground is best for a playground?

Students plan and conduct an investigation to compare the conductivity of different materials, and determine which type of ground surface might be most suitable for use in a playground.

Students will:

  • conduct an investigation about the transfer of heat to different surfaces.
  • make predictions and claims about what happens to the temperature of different surfaces when warmed by the heat of the sun.
  • observe, record and interpret the results of their investigation.
  • identify the differences in conductivity of materials.


Students will represent their understanding as they:

  • use oral, written and visual language to record and discuss investigation results.
  • record data in a table.
  • discuss findings and compare results.
