Racing Rings consists of three rods one each of copper, aluminum and PVC, Ring magnet is dropped down the PVC rod, it falls unobstructed, Two metal rods create an induced magnetic field to that adds resistance to the rings travel, metals are different, they fall at different rates
Radiation Can, for demonstrating solar energy and heat transfer, place in the sun or near a bright light bulb and watch the temperatures rise, Set of three 500ml cans
Radiation Can Kit, Demonstrate how two identically sized cans absorb and radiate energy differently, contains a lamp assembly with reflector and stand(bulb not included), smooth metal can, one black metal can, and thermometer, Includes activity guide
Radiation Can Set, Two identical sized screw cap metal cans (one smooth metal and other painted dull black) to demonstrate the difference in cooling rates of hot water inside the cans due to different surfaces, cooling rates attributed to thermal radiation emitted by the two cans
Radiation set of three sources contains 1 each Po-210, Sr-90 and Co-60 emitting alpha, beta and gamma radiation's. Ideal for demonstration and nuclear labs covering basic characteristics of radiation. The Co-60 is 1 uCi and the Po-210 and Sr-90 are 0.1 uCi activity.
