Focuses on practices related to the use of a microcomputer-based laboratory (MBL) in a high school chemistry course in which students studied gases and kinetic theory. Reports that little or no higher order thinking was employed as students engaged in using the MBL and that some alternative conceptions were still evident. (Contains 42 references.)…

Explains how the moon provides information about the evolution of the solar system and offers scope for physics-based investigations. Uses statistical analysis of real scientific data with which students can predict the diameter and depth of impact craters then compare them with data gathered in institutions or laboratories. (Author/YDS)

Presents a laboratory experiment on animal metabolism that uses a guided-inquiry approach. Discusses observed behaviors and improvements in students' understanding. (YDS)

Describes the Cognitive Acceleration through Science Education (CASE) project which can be used for all ability level students. Explains the Thinking Science activity, "The Behavior of Woodlice". (Author/YDS)

Uses microcomputer-based laboratories (MBL) to teach Newton's second law and the impulse-momentum relationship with a high degree of precision and accuracy while applying forces that change in an arbitrary way. (YDS)

Presents seven outdoor activities on the environment and ecology to be used at the K-12 grade level. Connects students with the environment they live in and develops the critical sense of place. (Contains 26 references.) (YDS)

Describes an activity for observing sunspots with binoculars and other readily available materials. Introduces students to daylight astronomy. (KHR)

Describes the "Name Game" in which students find out hidden information by asking questions of other participating students. Can be used for a variety of topics and test reviews. (YDS)

Describes a project that enriches astronomy lessons with hands-on activities facilitated by an astronomer. The project links professional and amateur astronomers with middle-level classroom teachers and informal educators. Families and community organizations are also involved in the project. Provides information on how to join the ASTRO network.…

Introduces an undergraduate course offered to junior and senior students on tracking and stalking in the wild. Finds and identifies fresh tracks of species selected by students as the ultimate goal of the course. (YDS)

Describes a laboratory activity on invasion biology to improve students' cognitive skills as well as manual skills. Requires students to develop hypotheses in which a common invasive species will succeed. Focuses on the red imported fire ant in the Southeastern United States, which is a non-native invasive species. (Contains 17 references.) (YDS)

Integrates story telling into a science activity on the density of liquids in order to increase student interest. Shows the relationship between mass and volume ratio and how they determine density. Includes teacher notes. (YDS)

Describes visual experiments that illustrate some basic concepts in chemistry and their principles. (KHR)

Presents examples of a space program and the media based on it for teaching chemistry. Discusses how to use videotapes during class to facilitate class discussion of chemistry topics. (KHR)

Offers some suggestions as to how science fiction, especially television science fiction programs such as "Star Trek" and "Star Wars", can be drawn into physics lessons to illuminate some interesting issues. (Author/KHR)
