Summary: Each page features two rocks of the same color on a black background with rhyming text to identify them (“Pyrite cubes reflect the light. Calcite is glassy–edged with white.”). After going through red, orange, yellow, green, blue, purple, black, and rainbow-colored, the author concludes, “Rocks in every shape and hue. Each one’s different, just like you!” The final three pages contain five questions about rocks and minerals with fairly in-depth answers. 24 pages; ages 3-7.
Pros: The photos of are gorgeous, and the back matter provides a good introduction to rocks and minerals.
Cons: There feels like a disconnect between the rhyming text, which seems most appropriate for preschoolers, and the back matter, which would work for kids up to age 10 or so.
