This 23-minute videotape for grades 5-8, presents the myriad of animal life that exists on the planet. Students can view and perform experiments and investigations that help explain animal traits and habits. Students learn about the incredible variety of mammals and how they survive in different environments while discovering which characteristics make these animals more advanced than others. A hands-on experiment in which students simulate how the amazing natural insulation of blubber keeps whales warm in cold water is included. This program is based on the concepts outlined in the National Science Education Standards for Life Science: (1) structure and function in living systems; (2) reproduction and heredity; (3) regulation and behavior; (4) populations and ecosystems; and (5) diversity and adaptations of organisms. A teacher's guide is also included. (ASK)
