Experiment
Biodiversity on a square meter
- ages 10–15
- 60 min
Students mark a square in the grass and count all plant and animal species inside.
Steps
- Conversation: what biodiversity is and why it is important.
- Groups mark a 1 x 1 m (3 x 3 ft) square with string in a meadow and in a mown lawn.
- Students count and photograph plants and animals, using a magnifying glass and identification app.
- They compare the results from the meadow and the lawn.
- They write their conclusions on a poster: what we can do to have more species on the school grounds.
Tip: A good follow-up is planting a wildflower meadow or an insect hotel.
Materials needed
- Magnifying glass for children (1 per group)
- Cotton string (1 ball)
- Tent pegs (4 per group)
