QCA
About this unit

In this unit pupils:

  • identify questions that are suitable for scientific enquiry
  • use a variety of strategies to answer scientific questions of different kinds
  • plan and set targets for a piece of work
  • consider the strength of the evidence, or the quality of the product, in relation to the question investigated
  • compare the different investigative methods used
  • work together in a group
Note

This unit provides an opportunity for pupils to focus on the variety of strategies that are used to answer scientific questions and to evaluate their own and others' investigations. It enables pupils to bring together skills learnt in other units and apply them to specific questions. The unit can be taught across years 8 and 9 or as a whole, towards the end of key stage 3. It is not intended to replace the work on scientific enquiry in other units.

This unit is expected to take 7-12 hours.
