In addition to a list of preparatory and clerical requirements, projects for the Boy Scouts of America Environmental Science Merit Badge include subjects of ecology, water pollution, land pollution, endangered species and conservation, and range from illustrating the greenhouse effect to determining 10 ways a household can make pollution-reducing changes. Boy Scouts must earn the Environmental Science Merit Badge before reaching the qualification level for Eagle Scout.
Environmental Science Merit Badge projects in the area of ecology include conducting experiments to chart how life responds to environmental changes. Changes include litter and pollution, land-clearing and the greenhouse effect. Scouts observe plant and vegetation response, animal response and insect response. This project ties in to the second requirement of the ecology experiment, which is reporting on an ecosystem. Scouts tell how ecosystems survive, how they are maintained and what can harm or alter them.
Water pollution projects include methods that people can use to reduce the spreading and effects of oil spills on aquatic life and waterfowl. In addition to the methods and the experimental outcomes, scouts describe the impact of the pollutants on living animals and organisms, as well as the chemistry of the water, and compose a 100-word report on the outcomes and effects.
