Unit 8B: Respiration

QCA
About this unit

In this unit pupils learn:

  • how cells are supplied with the materials they need for respiration
  • how cells in animals and plants release energy
  • that the process of respiration is similar in all cells

In scientific enquiry pupils:

  • consider earlier ideas about circulation including how and why these ideas have changed and developed
  • make observations and present these in a suitable format
  • consider how to deal with factors that cannot be controlled when working with living materials

This unit is expected to take approximately 9 hours.
