HON CHEMISTRY: So what do you think about reaction stoichiometry? Today you’ll practice what you learned yesterday with an assignment from the online textbook. Don’t forget there are also textbook pages here on the class website – check the tabs at the top.
Don’t forget to use the keys – and the roadmaps! And here are some answers so you can check your work.
CHEMISTRY: Happy Snowpocalypse! This lecture on polymers finishes the chapter! Did you realize molecules could be that large? And so many of them. But don’t you think polymers are cool? Here’s the lecture for Thursday. Interact with the vodcast! Answer out loud, take notes, make a list of any questions you have. For Friday, you’ll do the “homework” that usually goes with that lesson. Read the post for Friday to know more about the assignment.
In the meanwhile, don’t forget that you’ll have a test pretty soon after we get back. Check the syllabus for the date – and continue studying and practicing for that!
Some items for contemplation: how does the function of something relate to its structure. For example, why are certain plastics recyclable and others not…and what about dishwasher and microwave safe? Hmmmmm…

HON CHEMISTRY: Today you get a head start on the next chapter – and you get to see why it’s so important to be able to write and balance chemical equations! Interact with the vodcast! Answer out loud, take notes, make a list of any questions you have. For Friday, you’ll do the “homework” that usually goes with that lesson.
In the meanwhile, don’t forget that you’ll have a test pretty soon after we get back. Check the syllabus for the date – and continue studying and practicing for that!
So what do you think about reaction stoichiometry? Were you able to apply what you remembered about moles from earlier this year? Don’t forget the keys! Now all you need is some practice and you’ll have it down pat!!
PHYSICS: Happy Snowpocalypse! Today you get a head start on the next chapter. Here’s a short look at torque and another kind of equilibrium. Interact with the vodcast! Answer out loud, take notes, make a list of any questions you have. For Friday, you’ll do the “homework” that usually goes with that lesson.
In the meanwhile, don’t forget that you’ll have a test pretty soon after we get back. Check the syllabus for the date – and continue studying and practicing for that! And if I’m not mistaken – there’s a lab report due soon? Hmmmmm….
So how’s the balance in your life right now? 😉
Happy Snowpocalypse! Yay, you get to do chemistry and physics in your pajamas Thursday and Friday!! Sipping a cup of coffee or hot chocolate, watching a chemistry or physics lesson online – it doesn’t get much better than that!!
The lessons/assignments for each class will be posted by date and class like they usually are. For Thursday, you’ll watch a vodcast. Interact with the vodcast! Answer out loud, take notes, make a list of any questions you have. For Friday, you’ll do the “homework” that usually goes with that lesson.
In the meanwhile, don’t forget that you’ll have a test pretty soon after we get back – so continue studying for that!
I love you guys! Stay safe and warm!!
CHEMISTRY: Hey guys! Awesome job with empirical formulas, and now you’ve conquered writing molecular formulas! Here’s our discussion from Thursday. Don’t you think that molecular formulas are just like writing empirical formulas but with a twist at the end!
Have you started preparing for the test? It will be over ALL of chapter – plus the small bit from chapter 3. Be sure and checked out the Stuff to Know sheet for all of chapter 7 under the Test Info tab!
HON CHEMISTRY: We had to go fast, but do you realize what we did? We finished all 17 types of reactions today! We’ll practice them tomorrow since we had to go so fast today. Also, no audio on today’s recording, so I’m posting a vodcast from last year.
Careful when you work with any of these! For all single replacement reactions and reactions involving forming or decomposing oxide, be sure and refer to the Activity Series. Yes, you do get to memorize the Activity Series for the test – for the big test, not for the coming up quiz!
Are you working on memorizing all 17 types of reactions?! But don’t just memorize them. Make sure you can apply them as well. When you start to work any equation, first determine what type of reaction it is, then figure out what rule applies and follow it to determine the products. I believe in you! You can do it!! (and yes, I realize I am repeating myself, but I do and you can!)
CHEMISTRY: Isn’t it awesome that God has given us the ability to understand and use the world around us – even things we can’t see. Great job on applying the laws that we’ll need to use to find empirical formulas.
Let’s crank it up a notch tomorrow! 🙂

PHYSICS: Great job on the problems so far!! Here’s our look how kinetic and potential energy get involved – dart in the block of wood and the bird on the swing. This cute little bird isn’t on a swing, but he is one I came beak to nose with on a mission trip to Costa Rica!
What about even more practical applications? Hmmmm…..
HON CHEMISTRY: Moving right along with the 17 types of chemical reactions, here are the single replacement reactions – and you also got a head start on the activity series!
This makes 15 reactions so far, and we’ll do the rest tomorrow. Careful though, memorize, but don’t just memorize them. Make sure you can apply them as well. When you start to work any equation, first determine what type of reaction it is, then figure out what rule applies and follow it to determine the products. I believe in you! You can do it!!
