When radioactive elements decay they emit high-speed particles. These can be detected by use of a cloud chamber. The cloud chamber was invented by Charles Thomson Rees Wilson in 1911. The chamber works by saturating the air inside with alcohol vapor. Cooling the chamber with dry ice supersaturates the air. The energetic particles produced by the radioactive decay ionize
The Energetic Ray Global Observatory (ERGO) is a program that will provide students and teachers with a small detector that is capable of detecting the cosmic rays in a manner very similar to CosRAY and IceCube. The unit is small and will allow data to be exported automatically to Google Maps.
Plans for the Berkeley National Laboratory cosmic ray detector. This detector can be built by high school teachers and can be used to study cosmic rays in a method similar to the antarctic particle studies (CosRAY and IceCube).
Biodiversity is a central concept in understanding ecosystem functioning. Students explore how biodiversity is measured, impacted and can shift due to environmental changes to develop their understanding. Based off of the Microbial biogeography studies that Dr. Byron Crump is doing in the Arctic and around the world.
