Science Fair Projects About the Atmosphere [PDF ebook] 

By doing the simple science projects in this book, young scientists will discover if air has weight, if one can make a cloud, and the reason the sky is blue. The experiments use materials found at home or at school. Young scientists can take what they’ve learned from these experiments and use suggestions to create their own unique science fair projects. Detailed explanations explain the science used in each experiment. A glossary and full-color illustrations complete each title.
