My daughter’s Biology work this week was to make a wormery. We decided to make it a family task, and donned our gardening gloves. We needed:
Empty 2-litre plastic bottle
Dead leaves and vegetable peelings
Dark coloured paper
Here is what we did:
1. Cut the a quarter of the water bottle off at the top. Cut a slit into the side of the piece that has been cut off. This will be your lid.
2. Layer the bottle with soil and sand, drizzling water gently over each layer. We made the layers of sand thinner than the layers of soil. Leave around 5 centimetres at the top of the bottle empty.
3. Find some worms! (Plenty of digging happened here)
4. Place the worms on top of the soil and watch them burrow down the layers.
5. Add some dead leaves and vegetable peelings.
6. Put the cut-off part of the bottle back over the top to make a lid.
7. Cover the outside of the bottle with dark coloured paper and put it in a dark cupboard.
What we need to do over the course of the week is check it occasionally and see what has happened inside the bottle. We will also make sure that the soil is not completely dry. After a week we will take some more photos, then release the worms back into nature.
