The Way Science Works

From how to filter water laced with gravel, sand and charcoal to Einstein's theory of relativity, young scientists will find all they need to know in The Way Science Works: Discover the Secrets of Science with Exciting, Accessible Experiments by Robin Kerrod and Sharon Ann Holgate. Eight well-organized sections brim with information, color photographs and fun experiments like how to make a polymer slime and an electromagnet out of a screwdriver, battery and copper wire; easy-to-read icons designate whether kids can do them alone or with an adult. A few should only be demonstrated in a lab. Brief sidebars introduce important scientists and explain how their work shaped history. (Apr.)
