CSO
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.

Kids on the science day is trying out the radio dish demonstration
using a ping-pong ball to trace radio wave to be guided to an
instrument mounted on a telescope.
Figure 4 and 5. Steve Baca is guiding
kids to find out what they find in space in terms of light and sound.
Figure 6 . Ed Bufil is explaining how submillimeter radiation
from space will be guided into the optics of the 10.4 meter Leighton
telescope at the CSO.
