Each vial is a dropper bottle with enough freeze-dried serum to make 5 mL of reconstituted serum

Eight High-Quality Fossils for Introductory Classes

This set features a handy, economical selection of density cubes.

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

Exceptional perch specimens plus trays and pins, magnifiers, specimen storage bags, and a dissection manual are included in one package.

Exceptional earthworm specimens plus dissection trays and pins, magnifiers, specimen storage bags, and a dissection manual are all included in one package.

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.

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.

High quality density cubes for the classroom.

Observe the density across different materials and sizes.
