Lesson details

Key learning points

  1. Soil is an important source of nutrients for plants.
  2. Some plants may struggle to grow and survive in certain types of soil.
  3. Nutrients can be added to soil using fertilisers.
  4. Fertilisers added to soil make plants grow bigger and be more healthy.
  5. Fertilisers can be organic, such as compost and manure, or human-made.

Keywords

  • Soil - Soil is ground up rock mixed up with plant and animal remains.

  • Organic - Anything which is alive or was once alive is organic.

  • Nutrients - A nutrient is any substance that plants or animals need in order to live or grow.

  • Fertiliser - A substance containing nutrients that we can add to soil to make it better for growing plants.

  • Human-made - Something that is human-made is made or caused by humans.

Common misconception

Pupils may think that fertiliser added to plants is their ‘food’ and so is necessary for their survival.

Explain that plants do not eat food in the same way that we do but they do need nutrients to survive, grow and stay healthy. They get these nutrients from soil and we can add fertiliser to soil to increase the nutrients within it.

Setting up a simple observation over time investigation alongside this lesson would help pupils to see how fertilisers affect plant growth by purchasing two of the same plants from a supermarket and adding fertiliser to the soil of one of them.
