Bacteria, the smallest and simplest of organisms, are practically everywhere, affecting nearly every part of our lives. If we don't brush our teeth regularly, bacteria will cause them to rot and fall out; but without the bacteria that lives in our intestines, we wouldn't be able to digest our food. In other words, bacteria are both our friends and our enemies, as this solid introduction ably points out. Beginning with basic cell structure, this informative program explores bacterial shapes, environments, and behaviors, and visits a class engaged in an experiment with bacteria cultures, while illustrating key points and concepts with clear graphics and appropriate vocabulary. A fine addition to a unit on molecular biology, this is recommended. Aud: I, J. (E. Gieschen)
