Describes recycling related activities associated with the Earth Day celebration at the University School of East Tennessee State University. Activities involve tree planting, campus clean-up, student posters, assemblies, a schoolwide rally, and displays of recyclable items. A study examining attitude change revealed that hands-on activities…

Reports on a study of children ages 10-11 years (N=6) exploring forces. Reveals a gap between the ways that measurement is used in mathematics and the ways it is used in science. Reviews the focus of the National Numeracy Project. (DDR)

Describes a physics demonstration in which two-liter plastic bottles can be used to show how force relates to pressure and area. Identical drinking straws are launched out of similar plastic bottles with different-sized openings. This demonstration proves qualitatively that pressure is inversely proportional to the area exposed to an object when a…

Describes a program for teachers that focuses on environmental issues and stresses the development of collaborative relationships with scientists. (DDR)

Discusses the merits of investigative labs and how they change the role of students from passive direction followers to more creative and analytical thinkers. Focuses on the University of Minnesota's program in the Virgin Islands that involves undergraduates in research. (DDR)

Describes a course for talented high school students that focuses on DNA science and technology. Employs Cold Spring Harbor's DNA Science laboratory manual. Engages students in performing sickle-cell anemia and thalassemia tests in rabbits. (DDR)

Details the active-learning approach to teaching cellular respiration in an introductory, one-semester course for nonmajors. Focuses on a laboratory exercise designed to answer the question of what happens to food when eaten. Contains 19 references. (DDR)

Provides an account of one teacher's experiences creating and learning to market educational games. Urges others to consider developing educational resources. (DDR)

Describes a laboratory activity in a liberal-arts physics course entitled "Galileo to Newton and Beyond" in which students examine the orbits of Earth and Mars from heliocentric and geocentric viewpoints. (WRM)

Describes the New Mexico High School Supercomputing Challenge, a year-long project sponsored by New Mexico Technet, Los Alamos National Laboratory, and other statewide institutions that engages high school students, teachers, and professionals in complex scientific problem-solving that include written reports, mathematical models, and…

Lists 67 published or marketed chemistry games organized under the following categories: (1) general knowledge; (2) elements and atomic structure; (3) nomenclature, formulas, and equation writing; (4) chemical reactions; (5) solutions and solubilities; (6) organic chemistry, and (8) miscellaneous subjects. Includes a brief description of each…

Introduces puzzles that proved challenging and popular in the Mexican Chemistry Olympiad. Presents data showing that mainstream general chemistry students at the University of Nebraska-Lincoln enjoyed the puzzles and were challenged by them. (WRM)

Describes an activity in which students use metric measurements to find length and mass, calculate the towing strength of a bess beetle, and compare animal adaptations with human adaptations. (WRM)

Describes an activity in which students make careful observations about earwigs, then design their own questions for further investigation. (WRM)

Describes the development of an innovative, multimedia, interactive CD-ROM aimed at helping teachers tackle the problem that students have with evaluating science laboratory work. (Author/WRM)
