By doing the simple science projects in this book, young scientists will discover how distance affects images made by a convex lens, observe a wave model of polarized light, and explore the science behind mirages. The experiments use materials found at home or at school. Readers can take what they have learned from these experiments and use suggestions to create their own unique science fair projects. An explanation of the scientific method, safety tips, scientific illustrations, an appendix with science supply companies, a glossary, further reading with books and websites, and an index complete this title.
