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.
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).
This lesson investigates the impact of melting and freezing arctic sea ice on the properties of salinity, temperature and density that contribute to the stratification of ocean waters. This lesson combines several learning approaches including a hands-on lab, a web-quest and collaboration with other students.
Objectives
1. Students will be able to explain and demonstrate how Arctic
View sequential still images of thermokarst (thawed permafrost) at Horn Lake in northern Alaska during the summer of 2010. The video was made by researchers studying the responses of Arctic landscapes to permafrost degradation.
This article describes the remarkable efforts of a team of scientists to extract cores from deep under a frozen lake in Siberia, Russia. PolarTREC teacher Tim Martin joined the project which will provide an astounding record of past climates preserved in layers of lake bed sediment. The sediment, withdrawn in cores and shipped to labs in Germany, represents a continuous
The Polar Resource Book - Polar Science and Global Climate: An International Resource for Education & Outreach - was written to ensure that the efforts catalyzed by the International Polar Year (IPY) will continue to inspire educators, students, and emerging polar researchers with a shared commitment to outreach and education.

Icy IPY activities can be downloaded in word documents and tried in your classroom. From 'Blubber Gloves' to 'Experiments with Ice and Snow', there are a wealth of different activities to introduce students to the Polar Regions or complement their existing knowledge of the Poles.
The International Polar Year is a large international effort that has involved over 200 projects
