Discusses the purposes, advantages, and disadvantages of computer illustrated texts (CIT). Describes three separate CITs which demonstrate the variability that CITs have in terms of screen layout, programing style, and depth and range of coverage of topics in mathematical physics. (ML)

Describes a survey which was designed to obtain information on acid rain education. Reviews results pertaining to instructional time, instructional topics, use of labs from a common resource guide, and preference of materials related to acid rain education. (ML)

Reviews the space classroom that would have been conducted by Christa McAuliffe during the space shuttle flight. Includes lab activities, word puzzles, vocabulary lists, and graph reading exercises for elementary science students. (ML)

Illustrates how both large entities (such as stars and galaxies) and small entities (such as fundamental particles) obey the same physical laws. Discusses quantum mechanics, Newton's laws, and general relativity. (MLH)

Describes a number of activities, using pennies, which present children with problem-solving opportunities and reinforce some simple science concepts. (JR)

Describes the application of an inexpensive relaxation oscillator circuit which uses a thermistor or a cadmium-sulfide photocell to affect the rate of an audio pulse output. It is especially well suited for qualitative and quantitative measurement of heat or light in classroom situations because of its clearly audible output. (Author/JR)

Describes how a flannel graph can be inexpensively constructed and effectively used to teach the stages of cell division to junior high school science classes. (JR)

Reviews the principles of Monte Carlo calculation and random number generation in an attempt to introduce the direct and the rejection method of sampling techniques as well as the variance-reduction procedures. Indicates that the increasing availability of computers makes it possible for a wider audience to learn about these powerful methods. (CC)

Directions are given for the construction of mazes suitable for use in the classroom. The animal maze may be used to investigate small animal behavior, and the finger maze provides students with the opportunity to experience similar frustrations to those encountered by animals in the network of passages. (JR)

In the transition from the traditional science teaching approach to an activity centered curriculum, useful pieces of scientific equipment are often no longer needed and stored. Suggests ways in which the resourceful teacher can use this equipment to supplement the new curriculum with additional student activities. (JR)

Presents ideas from readers on techniques and equipment that might be useful in teaching secondary school science. Suggests how to construct cheap wall charts, modify a vacuum cleaner into a blower, construct a stereo microscope lamp holder, and outlines simple physics laboratory experiments. (JR)
