Circle study

To encourage students to have a closer look at the diversity of plants that grow in a small area.
How it works: 

Each member of the group, or pair, places their string in a circle over a chosen site on the ground, and then carefully examines the diversity within the circle.

Observations of the number of different kinds of plants, number or kinds of insects, tallest grass, smallest plant, etc. can then be shared with the group.

Participants can do circle studies at other sites in the area to determine any differences in diversity.
