This download includes a cover page and a graphic organizer that can be completed for each planet. I created booklets for my students, using the cover page and eight copies of the graphic organizer. Students conducted research in cooperative groups to complete their planet fact books. This was a great activity! The students loved it and it was an effective study tool. The third page of this download is great for early finishers! Students can brainstorm whether or not humans would be able to live on each planet. They must prove their answers using research from the graphic organizers.
