I was working on animal habitats with one of my students, and I (on a whim) pulled out these Star Wars planet cards that I'd made for another activity.

This student loves Star Wars, so this made the activity much more fun and engaging.
We also did a couple of other activities after reading about habitats. Here were the pages we used (all free from different teachers on TeachersPayTeachers):
