Harold Jacob's excellent Mathematics: A Human Endeavor introduces several mathematical ideas via the game of billiards. I suspect his text is the inspiration for the NCTM Illuminations's Paper Pool lesson plans. Although the Illuminations site provides a Java applet, I … Continue reading

In physics and calculus, we study radioactive decay processes. So as a lab, we could play around with some radioactive isotopes! For a variety of reasons, I settled for a simulation. That gives us the luxury of being able to … Continue reading

Springs can be stretched or compressed, and when this happens, they have potential energy. That energy is transformed into kinetic energy as the spring returns to its rest position. This lab allows students to observe a moving object encounter a … Continue reading

This lab can be used to observe the behavior of a brick sliding down a ramp. This complements the study of free body diagrams.

This lab can be used to investigate the relationship between velocity and the height above ground. We use it when studying potential and kinetic energy.

This lab can be used to investigate the relationship between velocity and the height above ground. We use it when studying potential and kinetic energy.

This lab can be used to investigate the relationship between velocity and the height above ground. We use it when studying potential and kinetic energy. The lab is based on Scratchy, the roller coaster riding cat. Clicking one of the … Continue reading

The Velocity and Time Lab allows gathering velocity and time data that students can use to determine average acceleration, and estimate instantaneous acceleration using slopes of the graph. They can also estimate how far the cars have traveled by finding … Continue reading

The Position and Time Lab allows gathering position and time data that students can use to determine average speed, and estimate instantaneous speed using slopes of the graph. In this lab, we will work the opposite direction. We have only … Continue reading

We are acquainted with the two-dimensional coordinate-plane in algebra class. We learn about graphing equations that have an input (or dependent) variable , and this input variable is associated with the horizontal axis. By habit, we refer to this as … Continue reading
