PHYSICS: I’m so proud of you – you’re doing a great job on thinking through these problems! Good luck in studying for your test. Practice, practice practice the problems, but don’t forget the conceptual stuff. If you get a chance, watch the Julius Sumner Miller videos on Newton’s laws in the Vodpod below, or look them up on You Tube. I think they’ll help a lot with the conceptual information. Help session in the morning at 7:15 A.M., if you need extra help. I’ll be praying for you!
Chemistry 10-29-09 Chapter 3 Test Review
CHEMISTRY: Great review today! Here’s the vodcast of the review, if there is something you have a question about. Make sure you check out the chapter 3 study suggestion sheet on Edline, and practice practice, practice! I believe in you – you can do this! And I’ll be praying for you!!
Physics 10-28-09 Net Vertical Force
PHYSICS: So would you ever jump out of a plane? Way too much craziness for me! How was net vertical force? Great job on the problems, but don’t forget things like terminal velocity and the why! And I still don’t know what’s so funny about a fish in an elevator?? 
Hon Chemistry 10-28-09 Hydrogen Emission Spectrum
HON CHEMISTRY: So hydrogen not only glows a lavender color when electricity is shot through it, but it’s more than just lavender light? Here’s the beginning lecture from Wednesday, we’ll talk more about it tomorrow. First – an overview of the problems with Planck’s constant. Kind of crazy at the beginning, but I want you to make sure you’re not just writing down formulas and plugging in numbers without understanding why. Understand why and you’ll get them right every time!
Chemistry 10-28-09 Moles, Mass, Atoms Problems Practice
CHEMISTRY: So how big a bucket do you think we’d need to hold a mole of frogs? Here’s the practice we did on the mole, mass, atoms problems. Did it help? Just don’t forget the conversion factor, and think through the problems. Put units first and then numbers. Make sure what you’re doing has a reason and makes sense!
Physics 10-28-09 Help Session – Friction
PHYSICS: Girl on a sled coasts down a hill… Here’s the thing. You can watch me do a thousand problems (okay, maybe not a thousand – but a lot!), and it won’t help. That’s what this morning was about. I don’t want you to copy what I do, I want you copy why I’m doing it. Make sense? You’re getting it…keep sledding and watch out for net forces!
Physis 10-27-09 Friction Problems on an Incline Practice
PHYSICS: It is what it says…here’s the practice we did Tuesday on the friction problems. You’re doing great, take it slow and easy….but not too slow, and make sure you practice! Think through the problems, where are the forces, what are they doing, what do they mean. Don’t memorize formulas, study, study, study, the why as much as the how. Tomorrow we go vertical.
Hon Chemistry 10-27-09 Photoelectric Effect
HON CHEMISTRY: So what are some examples of the photoelectric effect? Have you ever seen it in person? I’m betting you have! Here’s the lecture from Tuesday. Good job on the problems today. Make sure you are careful to learn the symbols and units for each of the quantities you’re going to use, it’s easy to get them confused.

Chemistry 10-27-09 Moles, Mass, & Avogadro’s Number
CHEMISTRY: So, what if you had a mole of popped popcorn? Nope, not the furry brown creature that burrows underground, it’s a whole different thing! Here’s the lecture from Monday on moles, mass, and Avogadro’s number. I still say he has a cool name…
Physics 10-26-09 Friction Problems & Friction on Inclines
PHYSICS: Who knew snow skiing could be so complicated! Well friction problems on an incline anyway. Here’s the lecture/problem review from Monday on friction problems with the applied force at an angle, and friction problems on an incline. Remember, drawing the diagram is super, super important. Label all the forces, and apply the concepts you know about net forces and resultant forces. And practice!!
