I have taught 5 years at a public school - 8th grade Physical Science and 9th grade Earth Science. I have a MSEd from Binghamton University. I am currently teaching and coordinating programs at the Kopernik Observatory in Vestal, New York. See www.kopernik.org All my labs, tests, and worksheets have been actually used in the classroom.
