"Freeze-Dried Specimens"

Equal mass cylinders of metals and nonmetals for density investigations.

Square column metal set for density and specific gravity studies.

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

Rectangular density set.

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).

Ensure perfect geometric alignment of your balsa fins on any Estes model rocket.

A fascinating demonstration!
