ENVIROTHON – A competition for high school students

The Envirothon is a high school environmental competition in which students compete in teams of five, answering hands-on, on-site questions about wildlife, forestry, soils, and aquatics. Delaware County teams compete in the Spring in an Area competition, which 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, held in mid-June. Teams at the Ohio Envirothon compete for prize money and a trip to the bi-national, Envirothon competition.


Envirothon Goals:

  • Develop critical thinking and problem-solving skills about natural resources
  • Stimulate, reinforce, and enhance interest in environmental sciences
  • A chance for high school students to work together as a team
  • An opportunity to meet other students interested in the environment
  • Time to meet professionals in different environmental fields
