In this outdoor activity and game, learners collect and sort leaf samples to determine how many types of plants grow in the activity site.

Fly a Leaf
Source Institutions
In this outdoor, windy day activity, learners "fly" and race leaves along a line to discover which types of leaves catch the most wind. Which leaves are the best fliers? Why?
