"Freeze-Dried Specimens"

Nine level conductivity meter shows the relative conductivity/resistance of liquids and solids. As the conductivity of the tested material increases, the number of glowing red LEDs will increase to a maximum of 8, which indicates a very good conductor. There will be zero glowing red LEDs if the material has a very low electrical conductivity (is a good insulator).

High quality density cubes for the classroom.

Educators can conduct a comprehensive array of density experiments with the density/slope class set.

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 set features a handy, economical selection of density cubes.

The Density Identification Set is ideal for an investigation lab.

Rectangular density set.

The Specific Heat Specimens Set can be used to determine the specific heats of a variety of common metals.
