Science KS 3 Unit 8B Respiration

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.
