Aquatic Ecology Objectives
- Identify assisting agencies and laws that govern Indiana waters, and develop a working understanding of the programs which benefit our water resources.
- Define a watershed and the interaction of its components.
- Define and understand the difference between non-point source and point source water pollution, as well as types of water pollution (organic, inorganic, thermal, toxic, etc.) and their impacts.
- Be able to conduct water tests and interpret data for assessing water quality ie: dissolved oxygen, BOD5, turbidity, nitrate/nitrite etc.
- Identify aquatic organisms, be able to classify them by pollution tolerance groups, and determine their indication of aquatic health.
- Understand the unique characteristics of freshwater resources (lakes and ponds, rivers and streams, reservoirs, wetlands, and groundwater).
- Understand the basic concepts of hydrology and the water cycle.
- Be familiar with the distribution of the Earth’s water and understand water’s changing states and processes of the Water Cycle.
- Be familiar with citizens’ simple actions that can be implemented to prevent nonpoint source pollution.
- Be able to identify and understand the interaction of segments of a community where water pollution can occur.
The Envirothon is a competitive learning event for high school-aged students, testing their knowledge of environmental resources including soil, water, forestry, wildlife and various current environmental issues.
The 2022 Indiana Envirothon regional and state competitions are scheduled to take place in person; however, this may be updated as county and/or state guidance changes. Please check this page and our Facebook frequently for updates.
