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
This is a suite of labs created by Michigan State University and the Joint Institute for Nuclear Astrophysics (JINA). It provides a number of lessons and activities in nuclear physics. It can be used to demonstrate the types of reactions typical in cosmic ray interactions and the interactions that the CosRay neutron monitors depend on.
Researcher Elizabeth Webb discusses her experiences working in the field with a PolarTREC teacher. She worked with John Wood in 2011 and 2012, and Tom Lane in 2013, on the Carbon Balance in Warming and Drying Tundra expedition near Healy, Alaska. (She primarily discusses her time with John Wood since this interview was taken in 2013, before Tom Lane's expedition.)
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).
How a PolarTREC Teacher Makes a HUGE impact with Polar Day!
PolarTREC alumni teacher John Wood organized a Polar Day at his school and it was a great success. This event is part of his ongoing commitment to sharing polar science with his students, many years after his expedition! Here is John's synopsis of the events, with some photos and
Soil decomposers, such as some bacteria and fungi, obtain energy needed for life from dead and decomposing plant and animal remains, known as soil organic matter. Soil organic matter is important to local ecosystems because it affects soil structure, regulates soil moisture and temperature, and provides energy and nutrients to soil organisms. It is also important globally, because
The local on-line newsletter interviewed Mr. Wood over the phone and talks about the upcoming expedition to the interior tundra of Alaska and how it will involve the students at Talbert Middle School in Fountain Valley.
