Physics 11-6-09 Potential Energy & the Law of Conservation of Energy

PHYSICS: So why is the first hill of a roller coaster always the highest? Here’s the lecture from Tuesday on potential energy and the conservation of energy. Thanks for trusting me, Arthur! :)

Hon Chemistry 11-6-09 Orbital Notation

HON CHEMISTRY: Happy Friday! See, it wasn’t so bad – orbital notation, I mean. :) You can do it! Don’t forget to use the Aufbau Principle! Homework for Friday night is to finish Wednesday’s questions, if you haven’t already, and to do Thursday’s questions. Have a great extra long weekend!

Chemistry 11-6-09 The Photoelectric Effect

CHEMISTRY: Happy Friday! Here’s the lecture from today on the photoelectric effect. How’d you like the field trip? What are some other applications of the photoelectric effect?

Physics 11-5-09 Work Energy Theorem

PHYSICS: Great job on the problems today – good connections between work and energy. I think you’ll like using the work-energy theorem, it’ll save you some time and a couple of steps. Don’t forget about friction!

Hon Chemistry 11-5-09 Quantum Numbers

HON CHEMISTRY: Great job on quantum numbers today! You set up the structure, we’ll put in electrons tomorrow. Don’t worry, it’s supposed to be a little strange, you’ve never heard of this before, right? We’ll go slow again tomorrow and you’ll get it, I promise! :)

Chemistry 11-5-09 Wave Properties & Problems

CHEMISTRY: Good job on the wave problems today! Do you remember them from physical science? Don’t forget that even though it’s really important to know the formulas, it’s verrrrrry important to know the symbols and units for all the properties you’ve learned about waves: wavelength, frequency, speed, etc. It’s all Greek, huh?!? ;)

Physics 11-4-09 Intro to Work

PHYSICS: Funny thing about words, all this work you thought you’d been doing, was it? Work, I mean? Great intro to chapter 5! Josh, I think you almost did move the lab station! :) I think you’ll all do great with the work problems, just remember everything from the last chapter and multiply by d!

Hon Chemistry 11-4-09 Bohr Model of the Atom

HON CHEMISTRY: I figured anybody who ditched his honeymoon to finalize his work on atomic theory deserved to have his picture on our website. So who do you think is right – Neils Bohr or Louie deBroglie? Let’s talk more tomorrow and see what you think then. By the way, what did you think of the animated version of the double slit experiment? Corny, I know, but it really has a ton a great, very accurate information. I’ve put it in the Vodpod below, if you’d like to review it again.

Chemistry 11-4-09 Intro to Waves

CHEMISTRY: So tell me again, if we’re supposed to be figuring out electrons, why are we studying waves? Here’s the lecture from Wednesday on just that. Make sure you know the types of electromagnetic radiation and the uses of most of them (all except for long waves). By the way, I put your favorite “Electromagnetic Radiation Song” in the Vodpod collection below, if you’d like to watch it again…and again…and again. :) We’ll explore waves further tomorrow – make sure you bring a calculator to class tomorrow.

Hon Chemistry 10-29-09 Spectroscopy Lab

HON CHEMISTRY: Fun field trip today! We’ve got to do that more often! :) Today we began the first part of the spectroscopy lab. Since we just began it, you don’t have to finish it tonight for homework, you’ll need to first finish your drawings tomorrow. Let me know if you have questions about how to “answer” the first part. You do the observations on regular notebook paper and your drawings on cardstock or heavy white paper, and mounted on construction paper or a small piece of poster board. Be sure to label everything. We’ll begin the second part of the spectroscopy lab tomorrow as well. The final lab report will be due Tuesday.
