Geodes!

For my Earth Science final project I had my students make their own geodes. They had to research and come up with a method of making geodes. They worked in groups of three and they had to have 3 geodes to display at the end. One was supposed to have the smallest crystals, one with the biggest crystals, and one was supposed to be the most natural looking. Here are some of their results. Turned into a very cool project. It took some of the students a lot of experimenting to get what they wanted. How often do students really get to "play"? Usually we just give them a set experiment and they have to follow it exactly. This was an awesome way for them to explore and figure out what worked and what didn't work.
