Describes a schoolwide project culminating in a week of activities on the theme of endangered species. However, most of the planning guidelines and many of the activities are easily adaptable to other themes as well. Lists eight tips for getting organized including a brief brainstorming session and how to handle committee meetings. (AIM)

Presents guiding principles for developing interactive lessons for the World Wide Web. Describes "Amazing Space: Education Online from the Hubble Space Telescope", a program where students study spectacular Hubble Space Telescope images of stars and star-forming regions to learn about the life cycle of stars and the creation of atoms. (JRH)

Describes two investigative labs that use live plants to illustrate important biological principles, include quantitative analysis, and require very little equipment. Each lab is adaptable to a variety of class sizes, course contents, and student backgrounds. Topics include the evolution of flower size in Mimulus and pollination of Brassicas. (DDR)

Explains the use of a card lab to demonstrate how a population bottleneck impacts genetic diversity and the survival of a population. Uses a standard deck of playing cards to show how age structure can magnify bottleneck effects. (DDR)

Recommends a number of techniques and transitional activities to bridge the gap between traditional cookbook activities and the type of inquiry envisioned by the National Science Education Standards. Includes discussion on techniques related to safety and the habits of good scientists. (DDR)

Describes laboratory and lecture activities in an introductory cell physiology course that encourage students to start thinking of themselves as scientists. (DKM)

Presents two simple and reliable ways for measuring protease activity that can be used for a variety of investigations in a range of biology class levels. The investigations use protease from a variety of sources. (DDR)

Physical education can serve as a vehicle for teaching science and make student understanding of certain personal health-related science concepts meaningful. Describes activities involving the musculoskeletal system, the nervous system, and the cardiovascular system. (DKM)

Details an activity designed to motivate students by incorporating science-related issues into a classroom debate. Includes "The Acid Rain Bill" and "Position Guides" for student roles as committee members, consumers, governors, industry owners, tourism professionals, senators, and debate directors. (DKM)

Describes procedures for a demonstration of the focal length of spherical lenses and mirrors using an aquarium, a flashlight, and nondairy creamer. Enables nonquantitative three-dimensional observation of these phenomena. (DDR)

Outlines the history of the educational role of the National Park Service under various leaders. Details the types of educational outreach programs that are thriving today and discusses their merits and successes. (DDR)

Describes a fun game in which students act as electrons, protons, and neutrons. This activity is designed to help students develop a concrete understanding of the abstract concept of atomic structure. (DKM)

Explores three classic turning points in science and presents close-up views of the scientists involved and their discoveries. Discussions include William Herschel and light; Lavoisier, Priestley, Scheele and oxygen; and Faraday and electromagnetism. Presents suggestions for experiments to demonstrate these discoveries. (JRH)

Presents a simulation that helps students understand the concepts of equilibrium and Le Chatelier's principle. (JRH)

Presents activities that involve students working as research and development scientists and exploring the world of glues-- how to make them, test them, and apply them to classroom projects. Enables students to gain technical knowledge and experience the excitement and responsibilities of being research scientists. (JRH)
