Crystals and Geodes (Rock On!)

Readers explore everything from tiny crystals hidden inside ordinary-looking rocks to enormous geode formations and even creatures preserved within geodes. The set includes four real specimens—amethyst, green aventurine, a natural geode, and a dyed geode—that children can examine as they learn about the characteristics and formation of these natural treasures. It also shows readers how to make their own crystal-filled geodes, adding a hands-on element to the science content. 

Combining fascinating earth-science information with real specimens and an interactive activity, the set encourages children to investigate geology firsthand while building an appreciation for the remarkable rocks and minerals found in the natural world.
