Out of Control

In this outdoor activity, learners release a portion of a lawn from human control—no mowing, no watering, no weeding, no pest control—and then investigate the changes that result over several weeks. Learners will discover how plants and animals colonize the area (replace the lawn organisms) once human impact is put on hold.
