Came across this wonderful presentation Karl Fisch, the Director of Technology at Arapahoe High School in Centennial, Colorado, put together for his students. It's called "Did You Know?" What a wonderful educator using technology to inspire and inform his students. It struck me as something all of us Tom readers would appreciate. Enjoy.
