COSMIC RAYS ON SPACESHIP EARTH

The Cosmic Rays and Spaceship Earth Web page is an outgrowth of a lecture presented to Delaware teachers at the Space Science Symposium, Nov 11, 2000. That lecture included a demonstration of a spark chamber, a device that makes cosmic rays in our environment visible to the naked eye.

• How the spark chamber works
• What to look for in the spark chamber
• The Spark Chamber in action

Educational institutions in the mid-Atlantic region can arrange a demonstration of the spark chamber for their students. Contact John W Bieber, Bartol Research Institute, University of Delaware, Newark, DE 19716. Phone (302) 831-2240. E-mail: john@bartol.udel.edu
