Describes a physical chemistry experiment which uses spectroscopy to measure the heat of formation of Na2SiF6. Discusses the opportunities for students to see the use of a familiar instrument in an unfamiliar application, emphasizing that there are often many ways to attack problems in science. (TW)

Developed by classroom teachers during the development phase of Minnesota's Graduation Standards, this performance package is made up of locally designed assignments that, taken together, show whether a student has learned and can apply the knowledge and skills related to comprehending technical information from documents or electronic media and…

Presents two examples of laboratory exercises using the World Wide Web for first-year medical students. The first example introduces the physical laws that apply to osmotic, chemical, and electrical gradients and a simulation of the ability of the sodium-potassium pump to establish chemical gradients and maintain cell volume. The second module…

Advocated is the use of interactive centers to supplement existing classroom laboratory experiences. Activities found in the center and modified classroom versions are described. The problems that arise when primary students meet sophisticated exhibits is discussed. (KR)

Describes a year long laboratory program for third, fourth, and fifth graders. States the goal of the program is to demonstrate what chemistry is, how it is done, and why it is fun and interesting. Provides a syllabus of the experiments and lists educational objectives. (MVL)

Discusses who has the right to determine the use of animals in scientific research which includes medical experimentation and the toxicity testing of compounds, ranging from pesticides to cosmetics. Provides a list of questions for consideration and discussion. (RT)

Describes the Assessment of Performance Unit (APU) Science project. Discusses the findings including perceptions of problems, procedural understanding, control of variables, and measurement strategies. Suggests a change from traditional learning strategies to more student-centered ones. (YP)

Demonstrates a laboratory to teach the concept of moment of inertia in which students are asked to identify four objects of equal mass sealed in unopenable containers by identifying the mass distribution of each object. Gives instructions to build an instrument to determine relative distribution of mass. (MDH)

Describes school science as a rite of passage, and exposes problems in school science that are made visible through the use of this metaphor. (PR)

Discusses computer simulations in science education and presents the results of a study of 39 ninth-grade earth-science students to determine the effects of computer-simulated mineral identification activities on test performance. Results indicated no difference in test scores between the group using real minerals and the group using a computer…

Outlines a laboratory group program for engaging large numbers of undergraduate psychology students in faculty research at small liberal arts colleges with limited research resources. Participating in the group enhances the students' interest in and understanding of research and improves their chances of being accepted into a graduate program.…

A communicating science module was introduced into an advanced undergraduate physical chemistry laboratory course. The module was integrated into the course such that students received formal instruction in communicating science interwoven with the chemistry laboratory curriculum. The content of the communicating science module included three…

Based on current theories of chemistry learning, this study intends to test a hypothesis that computer modeling enhanced hands-on chemistry laboratories are more effective than hands-on laboratories or computer modeling laboratories alone in facilitating high school students' understanding of chemistry concepts. Thirty-three high school chemistry…

This book, addressed to students for their independent use as well as to teachers as a supplement to the standard texts, contains nearly 100 practical science experiments that cover a wide range of subjects at different grade and ability levels. It is designed to involve students in active scientific experimentation, demonstrations, and projects…

Describes a two-quarter chemistry course designed to enable civil engineers to perform water analysis studies. (PB)
