Rocks (Bridgestone Science Library Exploring the Earth)

From School Library Journal Grade 2-4-Two serviceable introductions to popular topics. Olien touches on the types of fossils, some famous finds, and fossil fuels. Richardson outlines the three types of rocks, how they are formed, the rock cycle, and Mohs scale of hardness. Each book contains full-color photographs and a hands-on experiment. David Lambert's Rocks and Minerals (Watts, 1986; o.p.) and Joanna Cole's The Magic School Bus inside the Earth (Scholastic, 1987) are similar in scope.
