10.1
The human reproductive systems
Meet the sperm and egg cells, and follow them through the male and female reproductive systems.
10.2
The menstrual cycle and fertilisation
Follow the roughly 28-day cycle of the uterus lining and the egg, and see what happens when a sperm meets the egg.
10.3
Pregnancy, the placenta and birth
See how a baby grows for 40 weeks, how the placenta passes it what it needs, how the mother's lifestyle can affect it, and how it is born.
10.4
Flowers, pollination and seeds
Take a flower apart, see how insects and the wind carry pollen, follow fertilisation, and investigate how seeds are spread.
