Watch your worms mix up the different coloured layers in their chamber and feed them leaves. This product provides a great opportunity for children to learn more about worms’ importance in our ecosystem. Children are encouraged to collect their own worms and told how to in the 20-page activity guide, written by naturalist Nick Baker. Layer the tank with soil and sand, then watch your worms mix up the different coloured layers in their chamber over time. Add leaves to the top for them to feed on! Worms are easy to find, or you can purchase from fishing shops. This kit can be used all year round. However, in hot summer months please ensure your worms are kept in a cool environment and the soil is kept damp.
