Science KS 3 Unit 7B Reproduction

In this unit pupils:

• extend their earlier ideas about human reproduction and consider how offspring are protected and nurtured.
• consider and compare reproductive patterns in other animals with those in humans.
• relate what they know of the way their bodies change during adolescence to knowledge about human reproduction, growth and the menstrual cycle.

In scientific enquiry pupils:

• consider sample size in biological investigations.
• present data in bar charts and graphs.
• interpret data they have collected and data from secondary sources.

Teachers should make reference to their school's sex-education policy and personal, social and health education (PSHE) programme. They will also be aware of the need for sensitivity to the personal circumstances of pupils and their families.

This unit is expected to take approximately 8 hours.
