Describes an activity used in the science methods class at the University of Wisconsin to bring preservice elementary teachers into appropriate contact with children and to give them the opportunity to try out a variety of materials and activities from the newer elementary science curricula. (JR)

Discusses the Rugby clock as a source of project material, use of ZX81 for experimental science, computer dice analog, oil recovery from reservoirs, and computer simulation of Thompson's experiment for determining e/m for an electron. Activities/procedures are provided when applicable. Also presents questions (and answers) related to time-coded…

Seven complete secondary/college level acid rain activities are provided. Activities include overview; background information and societal implications; major concepts; student objectives; vocabulary/material lists; procedures; instructional strategies; and questions/discussion and extension suggestions. Activities consider effects of acid rain on…

Demonstrations, experiments, and classroom activities/materials for middle school science are presented. These include: additive color mixing demonstration; electricity activity and worksheet; atmospheric pressure "magic" demonstration; homemade microbalance; energy from soap bubbles; and a model used to demonstrate muscle pairs and how…

Student activities in an interdisciplinary, model rocket science program are described, including the construction of an Ohio Scientific computer system with graphic capabilities for use in the program and cooperative efforts with the Rocket Research Institute. (JN)

Describes a demonstration and role-playing activity focusing on differences between living/dead, definitions of living/dead, and situations in which active euthanasia could be morally right. (Author/JN)

"Whole body" denotes using the entire body to sense and experience a concept or idea. Typical whole body learning activities involve use of several senses: muscle sense, temperature, pain, pressure, and sense of equilibrium. Four whole body science activities are described, including identifying trees by touch. (Author/JN)

Presents a botany unit designed to provide understanding of a plant life cycle, plant parts and functions, and variety within the plant world. The unit is organized according to plant morphology (structure). Each section includes concepts fostered, suggestions for focused discussions, experiments, and activities to support concept development.…

Sedimentary patterns and hydraulic effects can be studies in model streams which are not to scale. The "Western River" is such a model which is being used effectively at Western Carolina College. Construction of the model, student exercises, and observations made when using the model are discussed. (Author/JN)

Describes physical science activities that civil/mechanical engineers (serving as resource persons) can use with students during units on force, work, center of gravity, simple machines, and other basic mechanics concepts. Activities are adapted from Career Oriented Modules to Explore Topics in Science for grades 5-9 (COMETS). (Author/JN)

Discusses the construction of lenses made out of ice, including the arrangement for mounting an ice lens on a camera. Also discusses brewing coffee in an ibrik (long-handled container tapering slightly toward the top), focusing on the physics of the brewing. (JN)

Reviews Outdoor Biology Instructional Strategies (OBIS) materials. The program, consisting of 97 nonsequential biology/ecology activities (games, simulations, crafts, experiments, data analyses), teach environmental concepts and an understanding/appreciation of the environment. Indicates effectiveness of the materials in motivating students,…

Highlights several basic ecological principles and suggests corresponding classroom activities for grades five to eight that revolve around a freshwater aquarium. Basic ecological concepts, adaptations, characteristics of aquatic habitats, and pollution problems are outlined in separate tables. A short list of resource materials is included.…
