Cool gravity activities Fun science projects about balance

Gr 4-6-Principles from physics and chemistry are wrapped up in high-interest packages that kids will find more than cool. From "Host a Stink Fest!" (Odor Decoders) to "Awesome Air & Water Rockets" (Distance Assistants), "Fast Frozen Confections" (Dry Ice Devices), and "The Old Cane Trick" (Gravity Activities), the five to six projects in each title will attract boys and girls. Each book begins with the same upbeat introduction and three chapters about the scientific method, keeping a journal, and safety. A sidebar gives adults tips on working with children and setting safety rules. Background on the science concepts involved is presented along with a complete list of supplies (some will need to be purchased). Each project includes a specific list and an estimated time for completion. The numbered instructions are easy to follow and are accompanied by small, close-up photos. Each project includes sidebars with guiding questions, ideas for extensions, an explanation of the principles exhibited, and real-life applications. A conclusion encourages readers to explore the concepts further. The photos in these attractive titles present a balanced group of children, although the stereotypical nerdy scientist on the first page is questionable-but amusing. These books won't be chillin' on your shelves for long.-Carol S. Surges, McKinley Elementary School, Wauwatosa, WI (c) Copyright 2010.

After a shared introduction about the scientific method and safety, each exclamation-point-heavy text tries too hard to make science super-fun. Five to seven activities explore physical and life science concepts through such topics as spying and the senses. Though the science is sound, the activities, particularly those requiring dry ice, are more advanced than the books' appearance would indicate. Glos., ind.
