Showy Science

By Hy Kim. With its Mr. Wizard approach to science, this book of more than 175 simple investigations is designed to satisfy the natural curiosity of a child. Basic scientific principles such as density, friction, geotropism, and fermentation are demonstrated in experiments about air, water, natural forces, plants, animals, microbes, light, and the Earth. Students can learn why the sky is blue, and how to "peel" an egg with vinegar. They can measure sugar content in pop and analyze plant pigments or make a barometer and a latitude finder. Each activity has a list of the ordinary household materials required, illustrated directions, and reasons behind the result. Grades 3–6. Index. Bibliography. 8" x 10½". Good Year Books. 313 pages. ©1994. GDY265.
