Today we did a rock cycle activity that works very well with middle school students. It is somewhat like an activity from Project Wet on the water cycle. Students go to different stations like: earth's interior, river, mountain etc. and the roll a die that tells them where to go next. Sometimes they stay at a station for a long time. I had one student that was at the earth's interior station for three turns and he told me that it felt like he had been there a million years. I said, "now you have the idea." This activity can be found at
You will need to scroll down to the "R's" to get to Ride the Rock Cycle.
