Provides real life assignments that can be used to help students apply chemistry laboratory techniques to solve environmental hazardous waste problems. Numerous diagrams are provided to aid in describing the experiments performed. (ZWH)

Describes an innovative, but not revolutionary, secondary education science program that is modeled after American graduate education. Discussions include a comparison of pedagogical approaches, implementation, the teacher, facilities, and teaching strategies. (ZWH)

Describes a safer, less expensive, preparation-efficient lab (microchemistry and mole) to aid teachers in teaching chemistry. Equipped with small-scale, hands-on activities, teachers can provide students an activity that allow them to collect, analyze, and discuss data all within a single class period. (ZWH)

Modifies a laboratory activity to ensure that consistencies exist between the laboratory objectives and the teacher's instructional goals (the constructivist learning theory). The changes are included in the article as well as a rationale for each change. (ZWH)

Provides guidelines for classroom discussions of bioethical issues. Equipped with an ethical reasoning model, teachers can help to prepare students to make responsible decisions about science-related issues. (ZWH)

Provides easy to teach and understand laboratory exercises for three fundamental concepts (plate movement, rock mechanics, and geologic time) that are often left out of the geology and Earth science curriculum. (ZWH)

Describes a science program (Saturday Science) designed to provide learning experiences that are thematic and stress critical/creative thinking as well as development of science process skills for elementary, middle, and junior high students. (ZWH)

A high school senior describes her adventures as part of an eight-week glacier expedition in Alaska and British Columbia. Also includes information on how to obtain unique summer enrichment opportunities for teachers and students. (ZWH)

Describes some of what a science teacher learned while participating in an amateur observing program that provided access to the Hubble Space Telescope. (ZWH)

Describes procedures for a hands-on activity for students that involves the construction of radio-controlled model sailplane (or glider) kits, exposure to basic aerodynamic theory and concepts, and some flight school on a midsized field. (ZWH)

Presents procedures for student-guided critical analyses of current topics in biology. (ZWH)

Describes easy to implement exercises that are designed to promote interest in physics by changing the laboratory environment. (ZWH)

Discusses the positive and negative aspects of outcome-based education. Also included in the discussion are recommendations for the successful implementation of outcome-based education. (ZWH)

Describes an activity that demonstrates the effect of specific variables on the acidity of coffee. (ZWH)

Describes a teaching tool that helps students understand that science is not a fixed body of knowledge but a continuous, dynamic process of human searching for answers often over a very long period of time. Using historical vignettes (short stories), teachers can help students make connections between the past and the present. (ZWH)
