Describes an experiment where elementary students determine the optimum angle of inclination for the greatest amount of distance a marble will roll when accelerated down an inclined plane. (PR)

Describes a laboratory activity "Observing Reactions in Solution." The activity can be used either as a laboratory or as a performance assessment for a high school chemistry class. (PR)

There is little recognition of the scientific traditions of non-Western and indigenous cultures. Non-Western scientists can take part in scientific activity by defining their own agenda, attitudes, values, behaviors, and world views, working on a different model without losing the benefits of science and departing from universal criteria of…

Explains reasons why students have misconceptions concerning pendulum swings. Presents a series of 10 pendulum task cards to provide middle-school students with a solid mental scaffolding upon which to build their knowledge of kinetic energy and pendulums. (PR)

Describes an experimental sequence using the force probe to develop the relationship between net force and acceleration. (PR)

Presents a lab experiment to demonstrate application of the iterative capability of spreadsheets. Activity involves a variable spacing parallel-plate capacitor and an electrometer. (PR)

Two chapters of the book, "Toward Inclusive Classrooms," are abstracted here. The chapters concern team teaching a seventh-grade science class and developing a sixth-grade science exhibition. They show how teachers cooperated to plan for inclusion of students with disabilities, how difficulties were handled, evaluation procedures, and…

Two experiments examined how learning from different media--real pulley systems or simple line diagrams--affected mechanical learning and problem solving. The first showed that subjects' learning improved equally in both cases; all subjects showed an increase in quantitative understanding as they learned; and subjects manipulating real pulley…

Sunrise Museum's Science Hall in Charleston, WV, offers 30 hands-on exhibits that introduce children to science. Museum programs use a 9-foot soft-sculptured, unzippable doll to teach children about nutrition and basic anatomy and recruit representatives from local businesses and industry to conduct weekend science workshops. (LP)

Presents a Project WET water education activity. Through a game of limbo, students experience the effort involved in meeting drinking water quality standards. Students investigate the relationship between water quality and water treatment and the ratio of one to a million. (LZ)

Suggests activities using large samples to simulate quality control processes in industry (specifically, manufacturing camera film). A series of small-group activities investigate the relationship of sample size to percent defective in batch sampling. Efficiency, cost of sampling, company reputation, and public relations are business factors…

Presents an activity integrating mathematics and science intended to introduce students to the use of metric measurement of mass as a way to increase the meaningfulness of observations about variables in life sciences. Involves measuring the nutrient tolerance of algae. Contains a reproducible algae nutrient graph. (Author/MKR)

Presents Texas Instruments' new Calculator-Based Laboratory (CBL), a hand-held device that connects to a graphing calculator, as a tool to make sophisticated measurements outside the classroom laboratory. Describes activities that use the CBL to make measurements in motion studies. (JRH)

Describes the Science Education Program and Leadership (SEPAL) project, a model science program for elementary teachers and students, designed to improve the teaching of science at the K-8 level. Focuses on experiential learning for teachers and promotes an inquiry-oriented approach to science teaching. (JRH)

Describes the effects of ability-paired student interactions on achievement as fifth graders (n=83) worked on laboratory activities relating to balance. Results revealed that low ability student achievement is greater, they speak more words, exhibit less distracting behavior, and move blocks on the lever less when they are paired with a partner of…
