Keywords

  • Rot - When something rots it decays or decomposes.

  • Compost - Compost is useful for growing plants. It can be made by rotting down certain types of food and garden waste.

  • Nutrient - Nutrients are substances that living things use to stay alive and healthy. Animals take in nutrients from their food.

  • Decompose - To decompose is to break down or decay.

  • Micro-organism - A micro-organism is a very tiny living thing.

Common misconception

Pupils may think that compost is just dirt or mud, or is no different from soil.

Explain that compost has a different composition to soil, and is full of nutrients that are beneficial to growing plants.

In Learning Cycle 3, a child makes a mini compost heap in a bottle. It would be great for children to have a go at making these themselves or to have a ready-made one for them to observe during the lesson. Ensure to carry out a risk assessment if children are working with soil and food waste.
Teacher tip

Equipment

If making compost, aim for a 50:50 mixture of greens (grass cuttings and other plants) and browns (dry leaves, twigs, hay, card, paper etc). Do not compost food waste. Keep the heap damp, not wet.
