"Bug City" is a video series created to help children (grades 1-6) learn about insects and other small critters. All aspects of bug life are touched upon including body structure, food, habitat, life cycle, mating habits, camouflage, mutualism (symbiosis), adaptations, social behavior, and more. Each program features dramatic microscopic photography and fun commentary and bug facts. The topic of this lesson is ants and contains information on the vastly different lifestyles, social behaviors, and appearances of the many species of ants. A demonstration of how to build a formicarium--an artificial ant nest that allows students to observe how ants live, work, and behave--is also given. The Teacher's Guide, which is included with the video, may be downloaded from the Internet. (WRM)
