HON CHEMISTRY: So tell me again – how do you know if a chemical reaction has occurred? And how could you record that for someone? Here’s the lecture from today on writing balanced chemical equations.
Here’s another hint – it’s not necessarily a good idea to try to make your own blue flame thrower! Click here to watch the Periodic Videos Blue Flame Thrower Video

CHEMISTRY: So… how big a bucket do you think we’d need to hold a mole of frogs? 🙂
Nope, not the furry brown creature that burrows underground, it’s a whole different thing! Here’s our discussion from Thursday on moles, mass, and Avogadro’s number. I still say he has a cool name… 🙂
HOMEWORK INFO: Do all the parts on the homework except only do b & c on the problems.
PHYSICS: So how many horsepower do you have? Hmmmm…..
Here’s the super short lecture from today on power – beginning with #46 from last night’s homework, and then a quick look at the power lab. Now go forth and conquer the power problems!
PHYSICS: Pretty nifty are simple machines! Did you remember all this from your physical science days? I don’t think you’ll have any trouble with efficiency and mechanical advantage problems. Give them a whirl and let me know!

CHEMISTRY: Now that you’ve learned to write and name chemical formulas, it time to take it to the next level and learn to use chemical formulas as a tool. Woohoo!!
Great job today with formula mass and molar mass! Be sure and show your work – and don’t forget to include the units!! (FYI – beginning of the vodcast is a look at oxidation numbers homework.)

HONORS CHEMISTRY: God bless you as you study for the test! Here’s our overview of the test from today.
Have you been using the “Chapter 7 Stuff to Know & Know How to Do” sheet? It’s a great way to get organized in studying for the test. I know it seems like a lot, but you can do it!
First priority – make sure that you have memorized EVERYTHING. Then, go to The Physics Classroom and/or sciencegeek.net and make sure you can write and name chemical formulas. Practice, practice, practice!!! Then start practicing the different kinds of problems – do at least three of each one of them. And also try those on sciencegeek.net. That’s always some good practice. God bless – I’ll be praying for you!
PHYSICS: From Tuesday – here’s our look at a few of the homework problems using the conservation of energy and work – #46 – 48, the skier pulled up the slope, the ski jumper, and the suitcase sliding down an incline to rest.
I LOVE the way you started thinking through these. Don’t give up on them. Treat them like a multi-layer puzzle. 🙂

CHEMISTRY: One man’s rust is another student’s lesson in chemistry! Great job today with oxidation numbers. Now it’s time to go and practice applying them! Try to do your homework without your notes first. Then go back and check and see what you actually knew. Great way to check up on yourself.
HON CHEMISTRY: Oh, my word! We finally finished the chapter! Have you had a chance to check out the Chapter 7 Stuff to Know sheet?
Also amazing – did you realize molecules could be that large? And so many of them! Don’t you think polymers are some pretty unique compounds? How about some applications?
Some items for contemplation: why are certain plastics recyclable and others not…and what about dishwasher and microwave safe?

PHYSICS: Great work today with the conservation of energy. (Get it? Great work 🙂 ) Here’s the lesson from today. And there’s audio!!
