Physics 3-31-14 Sound Intensity and Resonance

Posted on by

PHYSICS: Great applications of sound today – sound intensity and resonance!!

Lab tomorrow! Be sure and check the syllabus for the thLAB that you will do at home and the other one that you will actually do in class tomorrow.

Couple of items to apply for 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!

Hon Chemistry 3-31-14 Chapter 8 Overview

Posted on by

HON CHEMISTRY: Great overview today – for both “tests” – the written one tomorrow, and the lab one on Wednesday!

Have you been studying? Practice tonight (!!!) and also make sure you have everything memorized. You can get help in memorizing the 17 types of chemical reactions on quizlet.com (and also on the polyatomic ions from last semester). Here’s a link to the 17 types of reactions on quizlet that Nicholas did a couple of years ago – http://quizlet.com/11793692/chemistry-chemical-reactions-flash-cards/.

Another source of help is your online textbook at my.hrw.com. Click on the “Visual Concepts” or “Review Activities” tabs at the top of the chapter page for the extra tutorials and quizes. And, of course, the review activities at sciencegeek.net would be great practice as well. I love you and I’ll be praying for you as you study for your test!!
