Describes trigonometric calculations of the "fullness" (as viewed from Earth) of the outer planets as a function of their semi-major axes and their positions relative to Earth and the sun. (WRM)

Describes a short undergraduate course built entirely around a research trip to an astronomical observatory. (WRM)

Describes and explains a procedure for photographing the chaotic scattering of light. (WRM)

Describes an experience as passengers in a car that traveled around the "Wall of Death" during a country fair show. Explains the physics behind riding vehicles around the Wall. Finds that cars don't need to lean, motorcycles must lean, and people should lean to avoid nausea while traveling around the Wall. (WRM)

Describes the use of potassium chloride in quantitative project investigations into radioactivity. (WRM)

Describes a way of incorporating animations into spreadsheets using Excel software. (WRM)

Describes modifications to an apparatus for measuring the force of an object in circular motion. Explains how to accurately measure rotation rate with the use of a motion detector. (WRM)

Presents a low-cost activity in which students dissect cameras and build telescopes. (WRM)

Explains the use of Newton's law of proportional cooling in creating a realistic heating curve. (WRM)

Describes attempts to move physics discussions out of the classroom and onto the Internet where students can participate any time through the use of an electronic message board. (WRM)

Presents ideas for adapting active-engagement physics labs for students with mobility-related disabilities. (WRM)

Argues that high school teachers have given up on trying to teach equations and mathematics to poorly prepared, inner-city, or very average students. Describes a mathematical problem-solving physics course for all types of students from average to honors. (CCM)

Presents an organization of seemingly disparate convention and procedure statements and rules of basic electricity into conjugate relationships which can be used to reduce students' memorization loads and improve their understanding. (WRM)

Describes the organization and completion of a scientific field trip for a group of high school physics students that was organized primarily around a study of the Manhattan Project. The group visited the Trinity site, Los Alamos, several museums, and the National Radio Astronomy Observatory Very Large Array. Contact information for the various…

Offers a relatively simple analysis of the asymmetrical "sticking" and rolling behavior of two balls, one steel and one rubber, on an incline. Describes an Interactive Physics (TM) simulation designed to study the problem and gives rough experimental results. (WRM)
