"Freeze-Dried Specimens"

Beautifully illustrated in full color and highly informative, these pocket-sized field guides show each specimen in its natural habitat along with a detailed description of its history, habitat, range, and identifying characteristics.

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.

How do geologists classify minerals? This kit lets students observe and test a variety of specimens in order to identify and sort them. You can also use this set to introduce students to the methods and techniques that are commonly used in geological classification.
