This activity will allow your students to do research on their own to find out what makes each of our planets unique in our solar system. (Pluto is not included). A clue is given at the top of each page and the student needs to determine what planet it is describing and then use the information in front of them to fill out the number of moons the planet has, its position in the solar system, the length it takes to rotate and revolve, etc.
I set up 8 stations around my room, one for each planet, and I had the students rotate around the room looking up the information in the books I had gotten from the library. (Finding the latest editions is best.) You can also use this as an internet research project.
This activity makes it a little more challenging for the students since a clue is at the top of each page instead of a planet name.
