PHYSICS: Thank you J. T. and Joey for your help today! Cool thing, standing waves! Are you okay with constructive and destructive interference?
Tomorrow….on to sound! 🙂

CHEMISTRY: Great job practicing multiple bonds with Lewis structures today! Here’s the lecture from yesterday on double and triple covalent bonds, with resonance at the end.
CHANGE: As I told you in class, I’ve made a change to the syllabus – switched Thursday and Friday, so you can have the whole weekend to work on your project. Make sure you get a new copy of the syllabus. It will say “Revised.”
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!
