This kit is great for all doubting Thomases in your elementary through high school classes. Fast, fascinating and easy. This kit includes: Two black-colored blocks with rim for holding melting ice cube in place. The "cooler" one is of aluminum, which is an excellent conductor of heat. The ?warmer" block is of plastic foam, which is a very poor conductor of heat.

An economy collection of 6 commonly known igneous rocks. Igneous rocks are formed by the cooling of molten rock, either magma or lava. Each generous specimen is 1 1/4" to 1 1/5" and is contained in a resealable zip lock bag with a label. Grades 5-12. Ages 10-18.
Contains 15 representative specimens of intrusive and extrusive igneous rocks, each approximately 1.5" x 1.5". Grades 5-12. Ages 10-18.
Cargille Immersion oils meet ISO standards for performance
Available in 1/4 oz bottles
Types A and B are used for most fluorescent microscopy applications, type NVH.
Cargille Immersion Oil is required for high magnification and to obtain sharp images with clear resolution. These Immersion oils meet ISO standards for quality. Type A (low viscosity) and Type B (high viscosity) are used for normal microscopy applications with viscosities from 150-1250 (centistokes). The greater the gap between cover glass and objective, or condenser and slide, the more desirable high viscosity becomes. Type A and B are both used for most fluorescent microscopy applications, but Type A has a lower viscosity, which reduces any tendency to trap air causing image degradation and is easier to clean up.

This robustly constructed inertia demonstrator works reliably every time and is a great improvement on traditional versions of this classic experiment. A steel ball rests on a thin metal card on top of a pillar, and a spring-loaded catch is mounted next to the pillar. When the catch is released, a piston strikes the edge of the metal card sharply. The card flies out from under the ball, which remains in place on top of the pillar due to its large inertial mass. The card is tethered to the aluminum base for easy recovery after the experiment.
