PHYSICS: So how many classes to you have where you play with slinkies and watch bridges collapse!?! I’m just sayin’. Here’s the lecture from Tuesday on wave interactions. Cool thing, standing waves. Check out You Tube for a video on the Tacoma Narrows Bridge similar to the one that we watched today. I’ll put the others in the Vodpod below.
Are you okay with constructive and destructive interference? Tomorrow….test review. 🙂
HON CHEMISTRY: Wow! So that’s where the pretty light comes from! Great job on synthesis and decomposition reactions. We’ll finish decomposition tomorrow. Now go forth and practice what you learned! (The balancing equations part, not the playing with magnesium part!) 🙂
CHEMISTRY: Great job with double and triple bonds today! Here’s the lecture from Tuesday. Be careful about getting too happy with double bonding – count electrons and don’t forget CONS. And what else? Oh yes, PRACTICE, PRACTICE, PRACTICE! We’ll put one more twist on Lewis structures tomorrow.
