Source curriculum references

  • Evaluate risks
  • Make and record observations and measurements using a range of methods for different investigations; and evaluate the reliability of methods and suggest possible improvements
  • Interpret observations and data, including identifying patterns and using observations, measurements and data to draw conclusions
  • The tissues and organs of the human digestive system, including adaptations to function and how the digestive system digests food (enzymes simply as biological catalysts)
  • The importance of bacteria in the human digestive system
