Overview
Will my hot chocolate cool down faster if I add the cold milk now or later? Will ketchup flow faster if it's stirred first? Taking first place in the science fair has never been so much fun! These biology, chemistry, and physics experiments, devised by a real scientist and former high school chemistry teacher, really rock. That's because each activity answers questions that actually fascinate kids--whether they're exploring the laws of motion by smashing eggs against a wall, learning how to use diapers to prevent fire, or going "Supersonic" as they measure the speed of sound. Also, there's great advice on designing your own experiments, catching errors that could affect the results; and presenting the project so that it will impress the judges.Synopsis

Gr 4-7-This title opens with an introduction to science-fair projects, followed by sections devoted to project ideas in biology, physical science, and chemistry. Most of the experiments call for common household items. The simple, easy-to-follow directions are geared toward beginners. The layout is open, colorful, and appealing, with photographs of students and materials on every spread and boxed areas that highlight specific topics or ideas. Readers are encouraged to follow safety procedures, including wearing closed-toe shoes and goggles when necessary. The conversational text discusses how to pick a topic and offers a hands-on approach to planning the project, including an eight-week schedule checklist. Libraries would be well served by this title.-Maren Ostergard, Bellevue Regional Library, WA Copyright 2006 Reed Business Information.
