Describes a course at Michigan State University in which students carry out self-experiments in nutrition. Self-experiments help to impress students with importance of human nutrition and offer insights into problems associated with altered dietary patterns. A number of possible self-experiments in nutrition are listed. (JR)

Describes a number of experiments which give the student an opportunity to observe the effects of the electrical nature of matter without trying to explain why a given phenomenon is occurring. These experiments should be introduced before discussing the structure of atoms, and provide practical experience for later theoretical discussions. (JR)

Applications of wheels are shown to be an invaluable tool in teaching the processes and technology of science. (DF)

Three chemistry demonstrations are described: (1) partition coefficients; (2) Rutherford simulation experiment; and (3) demonstration of the powerful oxidizing property of dimanganeseheptoxide. Background information, materials needed, and procedures are provided for each demonstration. (JN)

This article about science fairs provides a list of topics children can research and suggestions for evaluating the possibilities of project ideas before children invest much work in them. Ideas for selecting a fair date and location, choosing judges, and involving parents and the community are included. (PP)

Information is presented for teaching about the formation of tornadoes and their effects. Ideas for relevant class discussion topics, writing assignments, and experiments to illustrate how temperature and air pressure changes involved in the storms work are also given. (PP)

Suggests how elementary teachers can go beyond the science text and use commonplace materials to create science experiments which sharpen students' observational skills and their ability to formulate testable hypotheses. Seven experiments are outlined, using materials such as paper, cotton socks, and mayonnaise. (SJL)

Describes an exercise which is currently used in a course in cell physiology at Oxford Polytechnic in England. This exercise can give students some idea of the molecular events involved in bringing about movement of chloroplasts (and other organelles) in plant cells. (HM)

Provides a discussion which is intended for chemistry college students on the ion cyclotron resonance (ICR) spectroscopy, the physical basis for ion cyclotron resonance, and the experimental methodology employed by ICR spectroscopists. (HM)

Gives a step-by-step description of a problem-solving microscale chemistry laboratory to show how this implementation of problem-solving teaching can be put into practice. Pedagogical and practical issues are discussed. (DKM)

Describes an approach that uses fiction as a springboard to environmental science experiments and discussions. (JRH)

Suggests that because controlled experiments are used extensively by professional ecologists to solve both theoretical and applied problems, experimentation should be a key component of secondary school ecology curricula. Describes five teaching principles to guide secondary school biology teachers in providing a more realistic view of the…

A teacher of students with hearing impairments outlines ways to integrate use of the scientific method into science laboratory experiences. A sample experiment is outlined, and the value of the applied science experiences for students who are concrete learners is stressed. (DB)

Described is an experiment which uses an autotrophic bacterium to anaerobically oxidize hydrogen sulfide to sulfate in a batch-stirred tank reactor. Discusses background information, experimental procedure, and sample results of this activity. (CW)
