- Extend this work by asking pupils to carry out a survey of weeds growing,
eg in a lawn, allotment or crop field. Provide a key for identifying weed plants and remind them how to use quadrats to sample a population.
- This could be set in the context of having to produce a report for the landowner about the types and numbers of weeds on the land. In the report, pupils could be asked to explain the problems that weeds present and to make suggestions about how to treat the land to remove them, and to identify possible consequences of the treatment.
