This activity is a way to create a cloud chamber in the classroom. A cloud chamber allows students to view "invisible" alpha particles emitted through nuclear decay. Alpha particles have a long history in nuclear physics--they are a helium nucleus and their emission during nuclear decay was one of the first ways we knew that atomic nuclei could
The IceCube Neutrino Observatory is currently under construction in Antarctica, and will help scientists search for elusive neutrinos that can help us map out the universe in new and exciting ways. I will be traveling to the South Pole this November and December to participate in this project, and report back to classrooms across the US. This stop-motion animated video
