Comments:
My sixth grade (11 and 12 year old) honors math and science students performed this experiment on Thursday, September 22 at 12:45 p.m. (solar noon) for our area on that day.  It was a perfect, sunny day to take our measurements.  My students learned a lot and enjoyed performing this experiment.  I am going to attempt to post their pictures to your web site.
