Describes an experimental project on boomerangs designed for an undergraduate course in classical mechanics. The students designed and made their own boomerangs, devised their own procedures, and carried out suitable measurements. Presents some of their data and a simple analysis for the two-bladed boomerang. (Author/MLH)

Presents a simple method of analysis in which the student can integrate, point by point, any interferogram to obtain its Fourier transform. The manual technique requires no special equipment and is based on relationships that most undergraduate physics students can derive from the Fourier integral equations. (Author/MLH)

In a Millikan oil drop experiment, there is a best measuring time for observing the drop, due to Brownian motion of the drop and the experimenter's reaction time. Derives an equation for the relative error in the measurement of the drop's excess charge, and obtains a formula for the best measuring time. (Author/MLH)

Describes activities to demonstrate Bernoulli's Principle, the effect of vibration on reaction time, formation of craters on the moon and weather simulation. (CP)

Presents data from a study to show that a mystique effect can occur for classroom students. Recommends that teachers provide orientation session before content objectives are taught. (CP)

Describes various teaching programs in year 11 science at Para Hills High School in Australia, including a system which allows the students to use half of their science time in individually programmed studies. (MLH)

Presents a computer program that uses radial and transverse star movements to make approximations of the closest approach in light years. In addition using the present actual visual magnitude the greatest magnitude attained is calculated. (Author/GS)

Describes the experimental procedure and expected outcome in the growth of rice seedlings with light conditions and water aeration as variables. (GS)

Describes an activities approach to the Man-Made World that is organized as a series of mini-courses to enable disadvantaged and unmotivated students to achieve a degree of technological literacy. (GS)
