"Freeze-Dried Specimens"

These economical and concise guides contain the right amount of information for reference during dissection.

Test your student's geology skills with this educational and fun activity. Students receive a bag of unlabeled rock specimens, then must test for physical and chemical properties in order to identify each rock sample. The easy-to-follow flowchart aids students in their classification decisions.

This set consists of 21 replica fossils in a plastic storage container.

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).

Each pocket-sized volume contains hundreds of illustrations and descriptions of the most common, important, and striking examples of each type of animal, insect, or other specimen.

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.
