Clip Description
With no eyes, five hearts and the ability to breathe through its skin, the earthworm is a truly remarkable creature. Earthworms make soil good enough to grow healthy plants and are a valuable source of protein for many different types of animal.
In this fascinating clip, we are shown the different parts of a wormery. A wormery is a special container that is full of earthworms and food waste. Inside a wormery, worms break down the food waste (such as vegetable peelings, tea bags and egg shells), turning it into compost. This compost can then be used by gardeners to help their plants grow. What is worm juice used for? Watch the clip to find out.
