Helpful Hints to Make
Your Team a Contender
The Envirothon is a problem-solving, natural resource education program for high school students. In the field, teams of students are challenged to hone critical thinking skills and work as a team. They answer written questions and conduct hands-on investigation of environmental issues in five categories Soils/Land Use, Aquatic Ecology, Forestry, Wildlife, and Current Environmental Issues. In addition to a written test, the teams also present an oral presentation solving a specific natural resource issue.
The Envirothon stimulates, reinforces, and enhances students' interest in the environment and our state's natural resources. The concept was created by the Pennsylvania Association of Conservation Districts as an outdoor hands-on competition. From "Environmental Olympics," the concept expanded to other states; and when the national competition was added in 1988, the name was changed to Envirothon. Envirothon affords a unique approach to teaching environmental education, and it's fun!
The continuing support of the program reflects the participation and support of the county conservation districts, clubs, agencies, and private corporations.
Reference materials for students and teachers are
available through local soil and water conservation districts. Envirothon can also be used as a curriculum
guide for classroom study. Conservation
districts in conjunction with cooperating agencies, educators, community, and
interest groups conduct regional competitions.
The top three teams of the regional competitions advance to the state
competition held in early May. The
winning team represents
Solutions to today's natural resource problems may originate as a grass-roots concern for nurturing our quality of life. Envirothon can be adopted by local schools to enhance the current environmental curriculum.
The challenges facing educators are formidable. Envirothon affords a ready-made program that fosters a well-rounded approach to teaching environmental education.
Tomorrow's problems will be more challenging but the solutions will be more apparent if students are encouraged to become environmentally aware, action-oriented adults who learn where to go for answers.
The competitive nature of the program motivates students to expand their knowledge of natural resource issues. Through this program, students will realize their responsibility as stewards of our natural resources.
Missouri State Envirothon goals include the following:
Promote environmental awareness and stewardship
Develop students' critical thinking, cooperative problem solving, and decision-making skills
Present balanced options for management of our renewable and nonrenewable natural resources
Provide awareness of and accessibility to resource organizations offering assistance in natural resource issues
The Envirothon concept began in
Envirothon provides students with an integrated approach to exploring five natural resource categories. It tests their creative, critical-thinking and team-building skills in a competitive format. Envirothon is a "day in the field" that tests students' knowledge and problem-solving skills at four ecostations Soils/Land Use, Aquatic Ecology, Forestry, Wildlife, and a fifth station on Current Environmental Issues. In addition there is also an oral presentation station where the team presents a solution to a conservation issue provided prior to the competition. One visual aid is permitted and submitted at registration.
Written questions and hands-on activities at the ecostations are developed by conservation district and resource conservation experts. Agencies and interest groups help devise, time, and monitor appropriate testing stations set up in the field.
Themes, written questions, and problem-solving tasks may be site specific, so each State Envirothon will be new and different. When the teams arrive at the state event location, they will register, confirm pre-registration information, and receive a brief orientation on contest format, rules, and scoring.
Teams will be assigned a test station rotation. Good teamwork, cooperative decision making, free exchange of ideas, and information pooling is important. All test stations are staffed by a monitor. Each test station requires approximately 40 minutes. Completed test sheets will be graded on site. Lunch is provided for the entire group at the state competition. After the competition and scoring is completed, everyone assembles for the announcement of the winning team. The top team is eligible for the National Envirothon contest, a challenging four-five day event. The Missouri Envirothon Committee works closely with this team to help prepare for the contest and arrange trip logistics.
The Envirothon competition is designed to get students involved in learning about many different environmental disciplines. The amount of information provided to Envirothon Teams may seem overwhelming to team members and advisors. This guide is designed to help teams prepare for the Envirothon by encouraging team work and a multi-disciplinary approach to environmental problem solving.
1. There are five topic areas and five team members. A team could assign each member an area of primary concentration and secondary concentration. This way, each team will have two members knowledgeable about each topic. Then, team members can share information with the others in practice sessions. Another way to divide the labor is to have several team members focus on natural history and identification and other members focus on the resource management issues for each section. Assessing the skills of each member will determine which is the best approach for your team. Remember, no resource professional can know everything. Teamwork is essential in the real world. Learning how to work as a team is essential to your success in Envirothon.
2. Make sure all team members are familiar with basic ecological terms and current environmental issues. They should also develop an understanding of the inter-relationship between all the topic areas and how the management of one resource may affect another.
3. Map reading is an important skill for natural resource professionals. Learn how to read and interpret a US Geologic Survey topographic map as an introduction to other map resources. Learn how to locate a site on a soil survey and interpret soil mapping units.
4. This guide contains sections on each of the five study areas. The introduction gives a rationale for studying the topic. The objectives provide a detailed outline of the kinds of information teams are expected to know. Based on these objectives, students can develop a strategy for studying each topic. Practice exercises are included for teams to use to strengthen their skills.
5. Each registered team is provided study materials for the Envirothon. Each section in this material contains an outline and a list of references. Resource professionals may be available through your local soil and water conservation district office to help the team prepare for the competition.
6. Advisors are encouraged to use the resource materials to develop environmental units for their classrooms. This will expand the Envirothon program to include more students than just those on the team. (In 1994, the Envirothon Program reached an estimated 3,000 individuals).
One of our most important natural resources is soil. This resource is often overlooked by students and teachers interested in environmental issues. Professional conservationists, however, recognize the importance of soil in natural resource management and the interrelationships between soil, water, and other resources. Soil provides a growth medium for all plant life on our planet, including food and energy resources. Soil also provides habitat, filters water, and is used in constructing buildings.

Diverse wildlife populations are valuable from many standpoints: as indicators of a healthy ecosystem, for recreation, and for aesthetics. Understanding a species' requirements and habits is the first step in ensuring the continuing existence of that particular animal. Proper protection and management of an animal's habitat will encourage optimum populations.
Envirothon Students should be able to:
identify common wildlife species from silhouettes, mounted specimens, or pictures. (Part of an animal may be shown instead of the whole animal). Keys will be used for more extensive identification.

This station changes every year to highlight environmental
issues that face
the nation. The hosting state for
the national competition selects the current issue for that year. Current issue information from previous years
is available upon request.
In addition to a hands-on testing station on the current environmental issue, there is an oral presentation station. At this station, the students will work together as a team to present a solution to an environmental issue posed to them prior to the competition. The students will be judged on numerous points including presentation skills, solution feasibility, participation, etc .
As more is learned about effective environmental management, it has become evident that an interdisciplinary approach to land use planning is needed. Natural resource managers are challenged to balance not only conservation and development, but also the competing resources they are trying to protect. For example, best management practices that are good for water quality may not be best for air quality. Students interested in environmental careers need to understand the many different types of land use (e.g., agricultural, forestry, mining, residential, open space, waste disposal, commercial, etc.) and the complexity of the issues faced by resource managers.
In Preparation for Envirothon Problem Solving, Students should be able to:
identify current issues
list federal, state, and local laws that regulate our land usage.
identify local land use boards/commissions and discuss their role in land use management.
understand the concept of watershed planning as a multidisciplinary approach to land use planning.
use a variety of resource maps to gather information about an area.
identify local resource agencies and professionals as contacts for land use planning efforts.
discuss private property rights vs. public good issues, including the "taking" issue.
Imagine that your town has recently acquired 50 acres of open space along a popular fishing stream. The area near the stream is relatively flat and wet pastureland (15 acres) and the remaining land is forested upland with moderate slopes and shallow to bedrock in some places. Three groups in town are interested in the area as follows: the local housing authority needs low income housing, the recreation department needs more soccer fields, and the town needs more cemetery space. Develop proposals for each of the local needs. Then evaluate them from a resource management standpoint.
Call your local Soil and Water Conservation District office to obtain contacts for resource professionals to help prepare a team for competition. Your local district staff can also provide information regarding your regional competition and registration.
