- Unit: Micro-Organisms and Man, Inspection Pack, National Trial Print. Curriculum Instructional Materials Laboratory Procedures Microbiology Science Activities Science Course Improvement Projects Secondary School Science Units of Study This unit, intended for students in grades eight or nine, is a revised version of ED 053 990. The teacher's guide lists the aims of the unit, behavioral objectives, suitable references and audio-visual aids, required apparatus and materials, and provides teaching notes for each activity, including comments concerning microbiological techniques. The core activities introduce major ideas concerning micro-organisms, particularly their role as decomposers in ecological cycles and their importance in economic production (bread, fermentation products). Students also choose from the following options: "Hunting Micro-organisms" (detection of bacteria and fungi in air, soil, and on body surfaces); "Other Micro-organisms" (pond-water examination); "Keeping Food Fit to Eat;""What's Brewing?" (cider, vinegar, beer, wine); "Getting Rid of Garbage;""Unseen in the Soil" (more extensive soil examination); "Disease" (infection in apples and goldfish); and a library assignment on "A Short History of Microbiology." The student's book provides instructions for some basic procedures, suggests experimental investigations, poses questions that are to be answered in a record book provided, and, in some cases, provides comments on the expected answers in an appended section.
