Lesson details

Key learning points

  1. Plants are living things, just like humans and other animals.
  2. Plants need water, light and a suitable temperature (warmth) in order to grow and stay healthy.
  3. Scientists ask questions and set up simple tests to find answers.
  4. Scientists investigate and observe what happens to plants if they do not get what they need.

Common misconception

Pupils may not know how to remove only one growing condition in order to compare plants.

Explain that a plant without water will still require warmth and light, and discuss group A, B and C's options as a whole class.

Keywords

  • Plant - A plant is a living thing that often has roots, stem and leaves.
