The Envirothon is a high school environmental competition in which students compete in teams of five, answering questions about wildlife, forestry, soils, and aquatics. Delaware County teams compete the last week of April in the Area competition. This competition is held in the southern/central part of Ohio with the exact location changing each year. The top four teams at the Area competition advance to the Ohio Envirothon which is held in mid June. Teams at the Ohio Envirothon compete for prize money and a trip to the international Envirothon competition.
