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

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.
