Volume 19 Number 3 1991 May Part of the science series "Wonder Why," Flight and Electricity are both hosted by Richard Zurawski. These fast-paced videos feature both a question-and-answer format and segments featuring children. Flight examines human attempts at flight: balloons, airplanes and rockets. The video features the historical devel­opment of both balloon flight and airplanes, and explains how all three types of flight work. A problem with this video stems from its inclusion of space flight as a topic. The explanation of rockets was both cursory and com­plex, and the video would have been more cohesive had rockets been omit­ted. Electricity focuses on static and current electricity. The video explains what electricity is and how it is gener­ated. It also features how a light bulb works and what life was like without electricity. Both videos present the information in short, interesting segments. Often segments are introduced by a "Feed­back" portion, in which children give their answers to a question. The videos also include interviews with experts, such as a pilot; "Let's make it" with Willy Wonder, in which a wing and turbine wheel are made; and an "Out and About" feature, which takes the viewer on a balloon ride. Flight and Electricity are both in­formative and entertaining. The concepts discussed were both explained and demonstrated. As the coverage of the subjects is superficial, the videos would serve as a good introduction to their topics. Recommended. Wendy Zwaal, Newmarket Public Library, Newmarket, Ont.
