Geode Rocks

I looooove rocks!!! Right now for science I am studying rocks and the 3 different kinds of rock: Igneous, Metamorphic, and Sedimentary rock!  All rocks fall into one of these categories.  Anyway you could call me a rock hound. I am specifically learning about geodes. Geodes are formed by mineral deposits inside volcanic or sedimentary rock "bubbles." My mom got a rock kit for me and in that kit there was a geode rock and I split it open with a hammer and there were crystals in it! I found another rock in my room that looked kind of like the geode I split open, so after lunch today I took it down under the lodge where the floor is cement and I started pounding on it with both sides of the hammer and I only made a bunch of dust from the rock. I had put the rock in a plastic bag so if chips flew up they wouldn't hit me.... I hit the rock so many times that I tore the bag to pieces. Seeing that I wasn't going to break it open I brought the rock down to Dewey. There are lots of tools in the wood shop and so Dewey tried hitting it open with a sledge hammer, rock drill, a sharp wedge and a couple little pieces came out and I could see there was crystal!!!! The drill only made a tiny indent but it had weakened the rock in that area so Dewey hit it with the sledge hammer one more time and the rock split in two!!! The inside is beautiful...it is cloudy blue in the middle and the rock around it is dark purple! Here are some pictures....
