This planet rocks! And so do my fourth graders!!!

As we learn about rocks and minerals, I am always searching for new, fun, and interesting ways to explore this "hard" topic. (haha) Technology is of course engaging, and for some, easy to get to, especially here at school with our classroom computers, iPad, and time in our computer lab. I found a great link that will help reinforce what we are studying, and will allow the kiddos to interact, and quiz themselves on what they know. I am curious to get some feedback and reactions. Let me know what you thought!
