students are required to research plants and animals to determine if they are a good fit for prairie life. The site then simulates the growth of a prairie including grasses,flowers, and various animals. This three-page interactive activity is designed to accompany the site and includes questions students must answer as they maneuver through the site. Great for small groups, as a center, or whole group instruction.
