Micro-trail - micro environments
Organise participants into pairs. Each pair should split up and find their own interesting microenvironment. Ask the participants to put a flag next to features in the micro-environment they find interesting, then get them to wind a piece of string around the flags to form a trail.
Encourage participants to write some notes or a story about their mini trail for their partner to investigate. Have all members of the group explore all the mini trails that have been set up.
Magnifying glasses enhance the sense of discovery.
