Obtain quantitative data for electrostatic experiments

A set of 15 samples of different materials used to challenge students to identify materials based on measurement of their density. For some specimens this will be straightforward. In other cases, it will lead to a discussion of uncertainty in measurements and data, and to an awareness that different materials may have nearly the same density.

This versatile timer with infrared sensors can be used to measure the speed of a moving object.

Students explore conservation of momentum with real-world machinery in this Collision Cart.
