A study of the use of seismometers in middle and high school classrooms shows that the existence of the National Science Education Standards would either increase or not effect how much they would use scientific equipment in the classroom. The study showed that the impact of standardized tests did not increase rote memorization.

The German-manufactured PHYWE apparatus offers a more efficient means of measuring velocity-of-light than many other methods and is easy to demonstrate to students of all study levels. The apparatus is a small black box with a transmitter/receiver, lens, and cables. It can be quickly set up and operated. An explanation of how it functions will enhance student understanding of light speed and measurement.

A new experimental apparatus called the 'chaotic sparking pendulum', that reveals chaotic two-dimensional orbits of a pendulum sliding over a set of magnets is developed. Schematic representation of the experimental setup and the forces acting in the pendulum bob is described.

An apparatus using air flow as analogous to electric current flow helps students understand the concepts of electricity better. The apparatus helps first-year students derive the relationships among voltage, current, and resistance. They can easily determine how changing one variable and keeping the other constant will influence the third. The apparatus is useful in explaining other concepts, such as the lack of air flow through the manometer and the movement of electric charge from high potential to low potential.
