Lesson Details
Key learning points
- Plants are living things, they need water to grow, stay alive and keep healthy.
- Without light, plants will grow taller at first, leaves lose their green colour and turn yellow or white.
- Changes in plant growth can be compared and described using observation skills.
- Different plants grow in different places with different amounts of light.
- Unhealthy plants without light can sometimes be recovered with light within a short period of time.
Common misconception
Pupils may think that a plant without light will grow less, rather than grow taller initially.
Ensure opportunities for first-hand observation of plants growing without light over an extended period of time.
