This is a project that can be used in a science unit exploring the planets, or adaptations.
Students imagine that they have discovered an alien from another planet. They need to include researched information about the chosen planet (could be real, or imagined). They also need to come up with the ways their alien has adapted to life on this planet.
Activities include researching a planet, creating an organizer on the alien, interviewing the alien, writing an article, and drawing a picture.
This can be used on a wide range of grade levels, depending on the amount of research you want the students to do. Each part of the project could stand alone, so it can be scaffolded for various ability levels.
