What plants need: final review

Lesson details

Key learning points

  1. The requirements of plants for life and growth include air, light, water, nutrients from soil and room to grow.
  2. In a conclusion, scientists explain what the results show or mean.
  3. Scientists often evaluate a completed investigation and suggest improvements.

Keywords

  • Question - A question is a type of sentence that asks something.

  • Compare - We compare things by looking at what is the same and what is different.

  • Conclusion - In a conclusion, scientists explain what their results show or mean.

  • Explain - To explain something means to make it clear.

  • Evaluate - To evaluate is to think about what you did and suggest any changes or improvements.

Common misconception

Pupils may think they should evaluate their investigation based on things like the neatness of their writing or how quickly they finished, rather than how they planned and carried out the enquiry.

Explain that scientists evaluate their investigations based on how they planned and carried them out, not on how neatly they presented their work or how quick they were to finish because this helps them to plan better investigations in the future.

Allow for plenty of discussion time during the lesson so pupils can see how their investigation compared to that of others. This will not only help them understand more about plant requirements but also to identify areas of their investigation that could have been done differently or improved upon.
