"Preserved+Plant+Materials"

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

Simple, Fast, and Fun

Huge wave demonstrations.

Unit consists of a sturdy metal frame carrying a DC motor with an eccentric shaft for exciting the vibrations. Clamp the frame to a table, attach a string and then simply use masses and a pulley to put tension on the string.

Plant Reproduction

Handy for observising and identifying macroinvertabrates.

Absorbs the widest range of acids, bases and unknown liquids, even those with high concentrations like 98% sulfuric acid and 30% sodium hydroxide. Chemical-resistant mat won't degrade or cause a dangerous reaction upon contact with corrosive spills. Eight layers of 100% polypropylene are thermally bonded to make PIG Mat exceptionally strong; won't rip, tear or fray even when saturated. Exclusive dimple pattern speeds wicking of liquid throughout mat for faster, easier cleanup. Highly absorbent, fine-fiber construction won't leave behind liquids or fiber residue.

Easily determine pH with the universal indicator chart.

Demonstrate the bending properties of light.
