Produced by the American Society for Microbiology, this site offers a number of resources for both educators and young users. Included in the first category is a collection of learning activities and other resources related to a new PBS series premiering this month, Intimate Strangers: Unseen Life on Earth; fact sheets and related links for the five principal types of microbes; a portrait gallery; suggestions for further reading; and a MicrobeWorld Explorers Journal that will feature reports from educators teaching about microbes. The young users section of the site includes six "microbe mysteries" that explain microbes and their many functions, news-making microbes, several experiments, and information on microbiologists and their jobs.
