Learning about the planets is totally "out-of-this-world" awesome! What makes it even better?--a project that lets your students immerse themselves in a real world application of learning about their planet and then sharing that knowledge with others.
This activity lets the students be creative, has them use research skills, requires them to present information to help persuade someone to see their planet, and has them look at facts on their planet.
This can be assigned as an in-class assignment, or as an out-of-class project. Great project for a range of grades and subjects!
