The compensation pendulum is a pendulum that is constructed in a way that its length does not vary by changes of temperature. As the temperature of the air around the clock goes up, the rod of a regular pendulum clock mechanism expands and the clock runs slower. Historically, it has proven easier to compensate for changes in the ambient…

For those in the profession of teaching physics who reside in or plan to visit the Los Angeles area, I would highly recommend a trip to the Huntington Library in San Marino, specifically to a permanent exhibit entitled "Beautiful Science: Ideas that Changed the World" in the Dibner Hall of the History of Science. The exhibit contains…

We present a showcase with interactive exhibits of basic physical experiments that constitutes a complementary method for teaching physics and interesting students in physical phenomena. Our interactive physics showcase, shown in Fig. 1, stimulates interest for science by letting the students experience, firsthand, surprising phenomena and…

Ten years ago I sat down with the first batch of students in our science/math teacher education program in the Philippines, then third-year students, and asked them what they could do for the opening of the new science building. One of them pulled a stack of papers out of his bag and put it in front of me: a complete script for a science play!…

Science museums and popular physics shows often exhibit a blower in whose air stream a ball is held hovering in equilibrium some distance above the jet's orifice. The weight of the ball, "mg," is balanced by the drag force of the turbulent air stream, often written as ?Cv[superscript 2]A, where "?" and "v" are the…

Describes the viewing sessions and the holograms of a holographic road show. The traveling exhibits, believed to stimulate interest in physics, include a wide variety of holograms and demonstrate several physical principles. (GA)

An electronic question and answer board is described which is used in conjunction with a school hallway physics display. (JP)

Describes construction of an exhibit which uses the acceleration of an elevator to distinguish mass and weight. (CP)

Describes the working of an exhibit in the Ann Arbor Hands-On Museum in which separated water drops from two nozzles collide to make interesting shapes. Discusses the calculation of the vibration frequency after the drop breaks away from the nozzle and the effect of drop size and surface tension on this frequency. (JRH)

Describes construction and operation of an inexpensive and portable educational hallway exhibit on color mixing. (JRH)

Describes the Colorado Scale-Model Solar System, a display illustrating the sizes and distances to the Sun and the nine planets on the campus of Colorado University. Discusses the model's educational value and uses for the classroom and the community. (MDH)

Discusses the general construction of an air track. Describes three demonstrations including elastic collision, forced oscillators, and coupled oscillators. Provides a diagram and four pictures. Suggests how a similar exhibit could be constructed with a modest budget. (YP)

Describes the physics displays at the University of Canterbury (New Zealand), including the facility, static displays, and interactive displays. Discusses the basic philosophy, general principles, and evaluation of the displays. (YP)

Describes a set of displays on the theme of coupled mechanical oscillators. Displays encompass three common demonstrations: (1) a coupled pair of identical pendulums; (2) a multiple-pendulum resonance demonstration; and (3) a Wilberforce coupled oscillator. (MDH)

Describes an exhibit containing four basic demonstrations relating to center of gravity and rotational equilibrium. The demonstrations involve (1) the stack of bricks, (2) the double cone, (3) the spool roller, and (4) the platform balance. (MDH)
