Describes a laboratory experiment in which Paramecium caudatum was used to demonstrate the toxic effect of cigarette smoke on the cilia of epithelium cells lining the trachea and bronchi of smokers. Provides background information and explains the procedure, including how to make a simple mechanical smoking device. (TW)

Describes a chemistry laboratory experiment in which thin-layer chromatography (TLC) is used to analyze urine specimens containing metabolites of the drug tetrahydro-cannabinol, which comes from the marijuana plant. The materials needed to conduct the experiment are listed, and the procedure and expected results are outlined. (TW)

Describes several laboratory experiments that are adaptations of clinical tests for certain genetic diseases in babies. Information and procedures are provided for tests for phenylketonuria (PKU), galactosemia, tyrosinemia, cystinuria, and mucopolysaccharidosis. Discusses the effects of each disease on the infants' development. (TW)

Describes a study in which paradoxes about seasons, hemispheres, and altitude were used to teach concepts in climatology. The misconceptions commonly held about the earth-sun distance relationship were used as an instructional strategy with an experimental group, which outgained the control group on an achievement test. (TW)

Identifies several ways in which an acid-base table can provide students with information about chemical reactions. Cites examples of the chart's use and includes a table which indicates the strengths of some common acids and bases. (ML)

Describes aspects of the preprofessional program for minority students in the health sciences at the University of Washington, including a summary of the history of the entire preprofessional program, factors bearing on selection and placement of students, and motivational factors. (CS)

Described is an interdisciplinary science course in speleology. Topics include geology, biology, chemistry, physics, and mathematics associated with speleology. The general outline of the course and a reference source list is included. (DS)

Described is an activity centered interdisciplinary science course made up of one investigation from the area of astronomy, geology, chemistry, biology, and physics. Each investigation requires different techniques, preparation and analysis. (DS)

Described is an alternative to the science fair for promoting student interest in science. High school students are invited to participate in a science olympiad, promoting high school college interaction. Suggestions for organizing events and activities of the olympiad are included. (DS)

Describes an interdisciplinary science and humanities curriculum for sophomores developed by the faculty at Boston University's College of Basic Studies. Three core courses (science, social studies, and humanities) are integrated into a year-long course which is team taught. The format includes both lecture and modular teaching approaches. (DS)

Described is the course content for a class on AIDS. The class focused on outreach, education, information and learning compassion toward people afflicted with the disease. A list of videos and films used in the course is included. (KR)

Describes how problem solving was incorporated into a clinical science curriculum by using a team teaching approach. The review of the content domain, the examination of objectives and test items, and the steps in the team development are included. The steps in development of the program are considered. (KR)

Presented is an activity that illustrates the relationship between the soil found in containers and soil in the ground including the amount of air and water found in each. Sponges are used to represent soil. Materials, procedures, and probable results are described. (KR)

Discussed is the use of volunteers to teach an astronomy laboratory course. Amateur astronomy groups were recruited to help teach this course. Advantages of using volunteers are listed. A list of student field experiences is included. (KR)

Described are ideas for the development of problem solving in the context of chemistry. Strategies for improving students' problem solving abilities are included. (KR)
