A diagram of the rock cycle ties everything together and a geology-themed project provides the opportunity for hands-on experience"--Provided by publisher.

"Introduces readers to the different types of fossils and how they form. Learn about key fossil finds, scientists who made . . . discoveries and contributions to the study of fossils, and how we use fossils today in the form of fossil fuels.

Explores the work of Aristotle, Linnaeus, Darwin, and other figures throughout history who have studied the natural world, and the technologies that allow scientists to study organisms at the genetic level. Helps readers understand how mutations lead to genetic variation, which in turn leads to natural selection.

"Vertebrates make up the majority of the animal kingdom. Learn about the importance of a backbone to some species and the unique structures and movements of those without one. Readers will use visual clues to apply their learning in classifying different examples of vertebrates and invertebrates"--Provided by publisher.

"[Presents the life story of] Sweden's Carolus (Karl) Linnaeus [who] started off as a curious child who loved exploring the garden ...
