- Use quick questions to establish pupils' knowledge of pregnancy. Use photographs, models, diagrams, video clips, CD-ROMs or ultrasound scans to look at the changes in a developing foetus from implantation to birth and discuss the sequence with pupils.
- Identify the structures within the pregnant uterus and explain the functions of the amnion and amniotic fluid. Discuss with pupils the foetus' need for nutrients and explain the role of the placenta in materials exchange. Ask pupils to label a diagram and use arrows to show movement of oxygen and nutrients from the mother to the foetus and the movement of carbon dioxide and other waste products from the foetus to the mother.

- identify the structures in a pregnant uterus and explain the function of amniotic fluid,
eg supporting the foetus, cushioning against shocks
- describe the general route taken by nutrients from the mother's digestive system to the foetus' brain
- state that oxygen, water and digested food pass from the mother's blood to the foetus' blood and that carbon dioxide and other waste products pass in the opposite direction
