Thousands of teachers and professionals throughout the United States and Canada guide students through the Envirothon each year. The Envirothon program combines classroom learning with outdoor activities, culminating in competitions at the area level (North East Ohio), state and international levels. This exposure to nature from a critical perspective and the understanding of human impacts on the natural world provide invaluable lessons, helping students understand ecosystems and our environment.
Envirothon teams are tested on their knowledge in five topic areas: Soils and Land Use, Aquatic Ecology, Forestry, Wildlife and a Current Environmental Issue. They are exposed to scientists and experts in each of the above fields, working hard, but having fun while learning. Open to high school students, a team may be sponsored by a high school, home schooled group or a scout or community service group. Each school can send two teams of five members each.
