Science at key stage 3    (Year 9)

Unit 9L: Pressure and moments

QCA
About this unit

In this unit pupils:

  • study pressure on solids and describe applications of this in everyday appliances
  • study hydrostatic pressure in fluids and describe an application, eg hydraulic jack
  • describe the operation of levers, including examples from the human body, which depend on the turning effect of a force
  • learn about the principle of moments

In scientific enquiry pupils:

  • make an appropriate number of measurements with adequate precision
  • account for anomalous results in terms of experimental technique
  • investigate balance about a pivot, evaluating strengths and weaknesses in their methods

This unit is expected to take approximately 7.5 hours.
