The major papers presented at the 1971 conference of the South Australian Science Teachers Association are included in this pamphlet. Scientists from industry, research institutions, and the police forensic laboratory, and practicing teachers presented papers which included descriptions of modern scientific techniques, discussions of the role of science education in meeting some societal problems, and a series of teaching techniques. The titles of the major papers are: "Education for Our Students in the 80's,""The Australian Science Education Project,""The Work of the Practising Scientist,""Forensic Science," and "Science and Culture." The descriptions of classroom techniques include projection techniques, teaching the topic "machines," demonstrations in fluid dynamics, and a series of demonstrations for chemical reactions illustrating the formation of new substances, energy changes, reversibility, reaction rates, stoichiometry, and catalysis; most of the demonstrations are suitable for use at the junior high school level.
