This is an announcement of a series of small booklets produced by the Science Teaching Project of the Curriculum Development Centre in Australia. Each booklet is designed to be of practical assistance to science teachers and guidance for the classroom situation. (CS)

Describes the use of practice weighings and handling of fluorescent compounds to assist in teaching students safe-handling techniques. (PR)

Describes the prosecution efforts regarding a chemistry teacher when one of the teacher's students was injured in an explosion in an attempt to make gun powder. In a different section, discusses nonscientists in science laboratories and the responsibilities of competent persons. (PR)

This manual was written as an aid to teaching assistants (TAs) who conduct the laboratory portions of life science courses at the University of Washington. In general, this manual does not present specific factual material. Rather, it offers suggestions on how to handle various teaching situations and provides a framework to use in many different…

Discusses the presentations of chemical demonstrations, hands-on experiments, and magic shows. Presents 12 guidelines to follow when presenting chemical demonstrations. Points out the obligations of the presenters for the safety concerns of the general public. Notes information available from the American Chemical Society. (MVL)

Presented are two chemistry demonstrations: (1) an alternative method for the demonstration of the properties of alkali metals, water is added to small amounts of metal; (2) an exploration of the properties of hydrogen, helium, propane, and carbon dioxide using an open trough and candle. (MVL)

Presented are 27 science activities for secondary school science instruction. Topic areas include microbiology, botany, biochemistry, genetics, safety, earthquakes, problem solving, electricity, heat, solutions, mechanics, quantum mechanics, flame tests, and molecular structure. (CW)

Explains how to use saliva instead of blood for classroom blood typing activities. Describes the protocol and equipment needed. (PR)

An objective of the American Chemical Society is to promote alternatives to landfilling for the disposal of laboratory chemical wastes. One method is to reduce the amount of chemicals that become wastes. This is the basis for the "less is better" philosophy. This bulletin discusses various techniques involved in purchasing control,…

This book is designed to develop sequentially a range of concepts and skills relevant to the basic disciplines of science. Emphasis has been given to the knowledge basis of science, the social context of science, design and technology, and knowledge and skills relevant to personal development. Students are provided an opportunity to engage in…

This paper on science instruction for learners with mental disabilities reviews the limited literature base in the field and provides practical information on teaching science in special settings. To assist in implementing best instructional practices in science education, the paper discusses the curricular make-up of science instruction; various…

With thousands of activities available, how does a teacher select activities appropriate for the classroom? Describes the guidelines of the "Science Activity Filter," which provide a useful protocol for evaluating science activities for their value in the classroom, allowing the teacher to use resources effectively, minimize discipline and safety…

Presents the following guidelines to consider before, during, and after hands-on inquiry: (1) plan and prepare; (2) create problem intrigue; (3) give students the responsibility of solving the problem; (4) offer feedback and guidance; (5) debrief; and (6) anticipate, prevent, monitor, and adapt. (PR)

Describes an experiment involving pineapples and gelatin that allows students to investigate the conditions that typically render an enzyme functionless, similar to the effect of nerve gasses. Discusses the materials, procedures, and results, drawing analogies to the effects of a nerve gas. (CW)

Presents the results of a chemistry program held at Purdue University from July 31-August 4, 1988. Topics reported include: chemistry's past, present, and future; new directions in chemical education, demonstrations and laboratories; and instructional strategies. Lists the 391 papers given at the conference and the 22 workshops. (MVL)
