Science is at work everywhere--in the kitchen, the sky, the ground, and all around us in plants, animals, machines, even the mind. Here are 100 ways to demonstrate how science works and for you to come out tops at your school fair. Stir up chemical magic and turn a copper pot green with oxidation. Prove that computers emit radio waves; create virtual 3-D with a polarized lens; and show off some "medieval ballistics." Every experiment will impress the judges!

"This extensive collection of do-it-yourself projects ranges from simple ideas using household materials to sophisticated plans which are unique."--Booklist "[There are] many good projects."--Appraisal "The directions are clear and straightforward."--VOYA From a device that makes sounds waves visible to a unique "pomato" plant, these 100 imaginative and impressive science projects will impress science fair judges and teachers--and astound all the kids in the school. Some of the experiments can be completed quickly, others take more time, thought, and construction, but every one uses readily available materials. Budding Einsteins can make their own plastic, build a working telescope, or choose from a range of ideas in electricity, ecology, astronomy, and other scientific fields.

With these 100 proven projects, students will have a really winning science fair experience--and hone their analytical skills, too. Best of all, the author makes even the most complicated subjects--such as DNA research--marvelously clear. The wide range of topics offers something for everyone: the many faces of acids and bases, the science of life (cells, enzymes, algae), perfect plant projects, the nature of hot and cold, chemical conundrums, and lots more. Students can construct a solar oven in a pizza box, figure out how many phone books can balance on a couple of eggshells, concoct a "snail salad,” and other blue-ribbon ideas.

Get ready to amaze science-fair judges, your teachers, and your classmates with these imaginative projects. Every project uses readily available, everyday materials and includes detailed instructions and diagrams to ensure your success, as well as helpful
