How Dangerous is your Garden?
Dick and Dom head out into a rainy garden with their helpers to find out about the science of soil and plants. Their first investigation involves worm-charming - testing two techniques known to bring worms to the surface of the soil. Other experiments explore how plants get water from the soil, and the best germination conditions for growing a healthy box of cress.
How Dangerous is your School?
Dick and Dom call in on teachers and pupils at school assembly to investigate the science of noise. After lunch, they head to the gymnasium to discover what happens when we exercise, and how muscles work.
