CSOLOGO1 CSOLOGO2CSO Participated the Onizuka Science Day 2011


  Onizuka Science Day was held on the 22nd of January 2011.  At the CSO booth, we had a vacuum system to show what happens for light and sound to travel in space, designed by Dr. Walter Steiger, and a small parabolic dish demonstration to show how a telescope collect radiation from distant astronomical objects.  For the small parabolic dish demonstration, by dropping a ping-pong ball down on the good surface of the parabolic dish which sat against the gravity, people learned the ball was bounced up at the focus position always.  For the parabolic dish demonstration, we used the 1.2 m parabolic dish donated by Oceanic Time Warner Cable located in Hilo in 2006.  We are so grateful for their warm hearted donation and their support for our public educational outreach efforts.   This year, Walter Steiger, Ed Bufil, Steve Baca and Hiroko Shinnaga participated the Onizuka Science Day from the CSO.
