In Biology or Environmental Science class students can study a specific National Park and then discuss the Biome in that national park. They will be able to research information about the Biome, but it will have a much better impact if it is an actual national park they are familiar with. Ideally, this is a group project with 4 members. There are 4 specific roles: Botanist, Zoologist, Geographer, and Meteorologist. Each person will pick their role within their group.
To make this as fun as possible for both you, the teacher, and the student remind them that they are trying to sell a vacation to this particular national park.
*For fun I tell my students that I will give the best presentation (whoever convinces me to go on vacation to their national park) a bonus on their test grade.
