Some topics that are covered in children's science books are dinosaurs, space exploration and the animal kingdom. Introducing children to science topics at a young age through reading can inspire an interest in science when they are older.
An example of a children's science book that covers the topic of dinosaurs is "Scaly Spotted Feathered Frilled" by Catherine Thimmesh. This book is intended for children between the ages of 9 and 12, and it explains how scientists use the fossils of dinosaurs to theorize what their appearance was like millions of years ago.
The topic of space exploration is address in the book "Beyond the Solar System" by Mary Kay Carson, which is meant for kids aged 10 to 13. This book uses history lessons and fun activities to get kids thinking about what is outside of the Milky Way. Another book about space for younger children is "Professor Astro Cat's Frontiers of Space," which was written by scientist Dominic Walliman.
