This compilation of four journal articles (Instructor, September 1980; Science and Children, September 1980; and Science Teacher, September 1980 and March 1981) focuses on volcanoes, particularly Mount St. Helens in Oregon. The first article, "The Earth is Alive!" describes the eruptions of Mount St. Helens, provides basic information on volcanoes, gives instructions for making a model volcano in the classroom, and lists resource materials on volcanoes. The second article, "Volcanoes: Coming Up from Under," provides information about the eruptions of Mount St. Helens in 1980, a discussion on how volcanoes are formed and monitored, a word list associated with volcanoes, and a source for obtaining a volcano poster for which an activity is suggested. The third article, "Beware of the Permanganate Volcano," discusses the hazards associated with permanganate demonstrations of volcanic eruptions. Alternate demonstrations are offered which include the ammonium dichromate reaction to simulate eruption, baking soda and vinegar to demonstrate lava, and punk to illustrate air pollution from volcanic ash and cinders. The fourth article, "Volcanology by Courier: Science in Stamps," provides five activities involving postage stamps picturing volcanoes or related scenes for use in the study of volcanoes. Activity topics include volcanic features, location of volcanoes, examination of land features which look volcanic but are not, and the making of one's own volcano stamp. (EM)
