The students were doing a variety of activities related to forestry and forest ecology. Activities included measurement of tree diameter, using a compass and measuring tape to map trees in 1/10th acre plots, estimating the number of leaves on the forest floor, estimating the weight of all the leaves, measuring canopy cover, identifying and sketching leaves; and sketching the layers in the forest.
This might seem like a lot of work, but this is not the first time these students have visited Audubon Woods. Third Grade students visited once last fall, and the other two grades have visited at least once a year since they were in Third Grade. By now the Fifth Graders are quite familiar with the preserve and the activities they are being asked to accomplish. The lower grades have less time available on site and less experience so they correspondingly do less work.
Here are a few images of the students hard at work as well as some nature photos from the two days.
