Ideal for tensioning lines.

Dual Scale.

Clearly Observe Inner Workings

Teach About Gravity

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.

Perfect for density experiments, use this set determine the mass and volume of each sample and graph the mass versus volume. The slope of the straight line that results is the density of the material.

Ideal for Index of Refraction and Total Internal Reflection Experiments
