Science 8: We marked pg 496 # 1-3 and reviewed the layers of the Earth. We took notes on Volcanos, followed by reading section 18.2 from a hand-out, followed by the first 28 minutes of National Geographic Volcano!. The second half was devoted to Lab 17A: Clocking Tectonic Plates. The procedure is due on Friday, and I will give you time to do Analysis a-e & g on Friday. Your final is on June 20th.
