Science KS 3 Unit 7C Environment and feeding relationships

In this unit pupils learn:

• how habitats vary.
• how plants and animals are adapted to live in a particular habitat.
• how plants and animals interact with their environment and with each other, including feeding relationships.
• about adaptations for feeding.
• how to link food chains to make webs.

In scientific enquiry pupils:

• consider the importance of sample size.
• make measurements of environmental changes and interpret these.
• survey the variety of living things within a habitat.
• investigate the activity of a small invertebrate, taking into account variables they cannot control.

This unit is expected to take approximately 8 hours.
