Lesson details
Key learning points
- Plants are living things and need the right conditions to grow and stay healthy.
- Plants need air, light, water, nutrients from soil, and room to grow.
- Scientists can investigate what plants need by observing plant growth when requirements are removed.
- A comparative test investigation can be carried out to investigate plant growth.
- In a comparative test investigation, variables must be controlled so only one thing is changed and another is measured.
Common misconception
Pupils may not consider plants to be living things because they do not move from place to place or have ‘babies’ in the way that many animals do.
Explain that plants are living things; we know this because they can move, grow and reproduce like other living things can.
