Science Fair Projects About Planet Earth [PDF ebook] 

支持

Hands-on experiments are a great way to engage young scientists. Instead of simply reading facts, they will experience the science that is happening in front of their eyes! The simple experiments in this book, illustrated in color, will unlock the secrets of planet Earth, including why Earth has layers, how continents move, and how we know Earth is round. By the time young readers are finished with the activities in this book, they will be ready to design some of their own to enter in their next science fair.
