Eratosthenes 2.0

In case you missed it, fellow physics teacher John Burk blogged a post-mortem of our collaborative lesson in which our students brought Eratosthenes’s famous experiment into the 21st Century: Measuring the Earth with Skype and a Stick. The feedback from his students were overwhelmingly positive! Check it out! (And be sure to subscribe to his blog while you’re there!)
