Students discover information about rocks, fossils, and minerals by solving geo mysteries. In the Mystery of the Floating Rock, they need to try to decide if a sedimentary, metamorphic, or igneous rock floats. They are given information about each of the rocks, they can see animated pictures of how each forms, and they can view a volcano erupting. In the Mystery of the Broken Necklace, students need to figure out what kind of fossils are the beads of a necklace. They are given information about crinoid fossils and can see a piece of the ancient Border's Sea. By clicking on each of the fossils, students can see what lived there long ago. They will also learn about the three kinds of fossils and how they are prepared. The Mystery of the Golden Cube has students deciding if a cube is a rock, mineral, or fossil. Information is provided about the cube's shape, hardness, color and streak, density, cleavage and fracture. Students are given the opportunity to test the cube's streak, hardness and density and the cube is compared to a gold nugget. Facts are given for 10 different rocks. Included in this site is a geologic timeline, questions and answers about rocks and fossils, and additional links.
