Physics 4-10-12 Sound Intensity and Resonance

PHYSICS: Hey guys, how in the world do you lose a lecture? Well, I can’t seem to find where I saved today’s lecture, so here’s a blast from the past on sound intensity and resonance.

Couple of items to apply from today’s discussion – so how does the whole hearing thing work? I mean, I know the little bones in your ear move, but why? Is resonance involved? Great item for application/discussion. And here’s another – why would different violins produce different sounds? I mean, is a Stradavarius valued so highly just because of the name? Let’s talk more about that!

Chemistry 4-10-12 Intermolecular Forces

CHEMISTRY: Well, here it is, the very last lecture from chapter 6 – intermolecular forces. (Don’t forget they’re also called van der Waals forces!) Tons of application, from bugs walking on water to little fishes breathing dissolved oxygen.

Need extra help or practice? Help session tomorrow, Wednesday, morning at 7:15ish A.M.

Good luck studying for the test – have you practiced Lewis structures and drawing ionic bonding? Great idea!! And don’t forget The Unit 3 section would be a great place to practice and check to see if you’ve learned what you think you’ve learned. I’ll be praying for you! You can do it!

Don’t forget that if you will be absent Thursday for the band trip, you will take your test tomorrow during your class and your study hall. You can also ask Mr. Berryhill if you can finish it during 7th period.
