Solar System! Solar System Research Question Cards & Solar System Activity Cards. This is a set of 32 solar system research center question cards, a sheet for recording the information during their research and 8 solar system activity cards, that gets them designing and creating. These cards can be used in several ways. If research is a new or developing skill for your students, the cards can be used to teach students how to use search engines and complete research. They can be used to teach your students how to take notes. The question cards make a great activity for earlier finishers, or as an interest sparker to introduce a unit on space. They can also be used as an internet scavenger hunt. Let the students see how many of the questions they can answer using research in a certain amount of time. This would be for your more advanced researchers. I have provided an answer key for the cards.
