Microscopes and Probes

What is a Million?

Students examine the concept of one million using the QX3 microscope from Intel as well as Internet resources. Investigations deal with measures of length, volume, and weight.

Bouncing Balls and Graphing Derivatives

In this activity, students use a motion detector, the TI-83 Plus graphing calculator, and their knowledge of first and second derivatives to construct a 'height versus time' graph, a 'velocity versus time' graph, and an 'acceleration versus time' graph of a ball as it bounces.  This lesson can be adapted for use on other TI graphing calculator models.
