Worms in compost heap


Set up a compost bin or heap. This can help reduce the amount of rubbish you put out for collection and can provide a good habitat for wildlife in your school grounds.

Once your compost heap is established you can use the compost to fertilise any flower or vegetable beds you may have in your school grounds.

This activity could also be completed as a science activity. You could look at soils and explore the types of matter that create healthy compost. Or you could use your study of compost to inform discussion around nutrients when learning about plants.
