Brain Zapped Science: Volume One

This appealing program for early-elementary students features four brief kid-hosted segments focusing on various science lessons. “Reason for the Seasons” explains how the Earth's tilted axis is responsible for the four distinct times of year on the planet, as well as why the northern and southern hemispheres have opposite seasons. “Mom, Laundry, Computers, Aliens!” explores the causes of erosion and weathering, while “Swimming for Science” explains how theories evolve from hypotheses that can be tested, applying the method to a study of a swimmer's most productive stroke. Finally, “Game Show: Renewable or Non-Renewable Resources” presents a staged quiz show about fossil fuels versus other energy sources. DVD extras include a Spanish-language version of “Reason for the Seasons” and “BZ Quick Tip: The Trick of 9s,” which details an easy way to multiply by 9. Recommended. Aud: E, P. (T. Keogh)
