This article describes how a third grade class (ages 8-9) conducted a temperature-related science experiment. The goal of the experiment was to build on the following question: What would happen if you took three different thermometers, all reading the same temperature, wrapped them in three different socks, one woollen, one silk, and one cotton,…

The exponential function model of radioactive decay and the concept of a half-life are used in nuclear experiments that appear in introductory and intermediate laboratories. In our interactions with students, we have found that students at all levels have significant confusion about both the term exponential and what is meant by a half-life as…

This article describes a collaborative learning experience in experimental design that closely approximates what practicing statisticians and researchers in applied science experience during consulting. Statistics majors worked with a teaching assistant from the chemistry department to conduct a series of experiments characterizing the variation…

Describes an inquiry activity in which students explore the variables that influence the amount of time it takes a ball to roll down an inclined plane. Relates features of the activity to recommendations in the NCTM Standards. (MKR)

Described is a lesson in which the midpoint of the measuring stick (center of gravity), the balance point of the stick (fulcrum) and the arithmetic mean are assumed to be the same point. Provides content background, lesson outline, procedure, evaluation, teacher notes, and diagrammatical representations. (RT)

Introduces microcomputer interfacing as a method for explaining and demonstrating various aspects of the concept of function. Provides three experiments with illustrations and typical computer graphic displays: pendulum motion, pendulum study using two pendulums, and heat absorption and radiation. (YP)
