Sharing Space Facts

Today I passed our note cards and each student was given two minutes to print all the facts they could about space (moon, Earth, stars).  After two minutes  I teamed them up and they share their facts and recorded new facts; again they were given two minutes.  Then they were in a group of four.  At this point some of them had a full card-hooray!!!
Eventually, we got back as a class and I had them highlight a fact on their card that they did not know before this lesson!  We then discussed our cards!  I was surprised by the facts they remembered and the new ones they presented!
