Ecology Lesson Concepts

Population ecology lab using nets lets students go into the environment and take samples of insects. Another great ecology experiment is for students to make observations and conclusions about biodiversity around the school. An example ecology activity lets students be predators, prey and resources to determine the population size of a species. Ecology projects include researching different biomes. Ecology worksheets and exam / test / quiz questions also provide help with evaluating the student’s progress.
