Describes the activities of the kNights of Physics, a group of preservice teachers, whose goal is to spread the knowledge of the fun of physics to elementary students and their parents. (JRH)

Describes activities designed to give summer school students an appreciation of the value of an integrated approach to scientific investigation. (JRH)

Presents an activity to construct a tester for electrical resistors. Contains discussion questions, extensions, curriculum correlations to health and art, and home links. Includes a reproducible student worksheet. (MKR)

Describes the history, construction, and use of a diffusion cloud chamber to detect and study radioactive materials. (MKR)

Presents examples of how the U.S. Constitution is continually being interpreted due to new technological developments. Through the use of a simulated course, students can actively participate in making decisions about our technological society. (MKR)

Discusses the behavior of objects in fluids having densities that increase with depth. Provides equations and a diagram of the system providing the temperature gradient. (MVL)

Provides two experiments that do not give the expected results. One involves burning a candle in an air-filled beaker under water and the other burns the candle in pure oxygen. Provides methodology, suggestions, and theory. (MVL)

Discusses the use of contests to keep physics interesting and exciting for the students. Includes: balloon car, egg drop, tennis ball catapult, bridge building, mousetrap vehicle, musical instrument, slide photo, electric junk dissection, windmill generator, and solar heater. (MVL)

Presents ExploraVision as an opportunity for elementary teachers to work with their students while they are still quizzical and curious. Participating student teams choose an existing technology and envision how it might be used in 20 years, presenting their idea in a 10-frame story. Describes preparation of a student team to enter the contest.…
