Gr 5-8-Two space adventuring animated green aliens, a female captain and a male corporal, narrate the excellent, well-written scripts of Oceans, Soil, and Weathering & Erosion. The aliens' conversation is sprinkled with the right amount of humorous dialogue, which will attract and keep the attention of middle grade viewers. The well-scripted combinations of live action, 3-D animation, and graphics make these educationally sound programs fun to watch. Each video covers the topic fully and includes graphics, which accommodate visual learners. The well-selected video footage of each topic is stunning and will keep the attention of the viewers. Animated segments of geographical features are well illustrated and labeled for easy understanding. Multicultural, mixed gender, believable adolescents perform investigations. The directions are easy to follow, and the well-explained activities can be easily replicated. Follow-up discussion and activities, along with suggested Internet and print resources are listed in the teacher's guide. These videos enjoy very good technical aspects, and the teaching objectives are well achieved. They are excellent introductions or overviews for class units or individual viewing. This excellent series should be purchased by every middle school science program and for public libraries with non-print home school collections.-Kathy Dummer, formerly Newcastle Middle School, WY Copyright 2000 Cahners Business Information.
