Science KS 3 Unit 9B Fit and Healthy

In this unit pupils learn:

• how the human respiratory, digestive and circulatory systems interact to maintain activity.
• about the functions of the skeleton.
• about ways in which diet, exercise, smoking and drugs affect health.

In scientific enquiry pupils:

• find out how scientists linked diseases to a lack of specific nutrients.
• consider how the work of different scientists has contributed to a medical advance.
• work collaboratively to collect sufficient valid and reliable data to form conclusions
• evaluate conflicting evidence.
• investigate reaction time, considering how factors which cannot be controlled can be taken into account.

Teachers should make sure that work on tobacco, alcohol and drugs and eating disorders in this unit is consistent with their school's PSHE programme. Teachers will be aware of the need for sensitivity to the circumstances of individual pupils and their families.

This unit is expected to take approximately 8.5 hours.
