CHEMISTRY: You did it! We finally finished the chapter. Here’s the lecture from today on the explanation for a curious property of water and an overview of the test on Monday.
Do you feel like you are under water with all that you have to do? Let me give you some hints about making out your own study suggestion sheet for the test.
Here’s a good place to start getting organized. Make a chart, a really big chart of “What I need to memorize,” “What I need to know how to do,” and “What I need to be able to apply/discuss.” Then start practicing the things you have have the list!! Practice is especially important on the “problem” like objectives such as Lewis structures, drawing ionic bonding, etc. I would also encourage you to make lists of possible discussion questions and then practice answering them for the test. If there are things you are unsure about, go back and watch parts of old vodcasts.
A great way to help you study is to use the “Visual Concepts” part of the online textbook for this chapter. And don’t forget that a great place to prctice dot notation and Lewis structures is at sciencegeek.net and practice the things from our chapter that are in the Unit 3 Review Activities. You get feedback right away to know if your answer is right or not, and that’s a good thing.
We’ve covered quite a lot in this chapter. God bless you as you study! I’ll be praying for you!!
CHEMISTRY: Are you ready? It’s a little overwhelming, isn’t it? Here are a couple of things that will help! Super important things that will help!!
The first vodcast has the answers/discussion for the Most Abundant Elements questions and the Chapter 5 Sample Test. No one in my other classes asked about the homework questions you had asked about earlier – #50 – 53, but 7th period did (way to go, 7th period!), so I’ve posted that short vodcast for you also. Super, super important for the test! You’ll really want to watch it as you study!!
And for the second one – how to work #50 – 53 on the Chapter 5 homework. Super important!!
HON CHEMISTRY: Well, here it is, the very last lecture from chapter 6 – intermolecular forces. (Don’t forget they’re also called van der Waals forces!) Tons of application, from bugs walking on water to little fishes breathing dissolved oxygen.
Now to seriously start studying for the test! Have you practiced Lewis structures and drawing ionic bonding? Great idea!! Also, don’t forget the interactive review quizes in the online textbook and also www.sciencegeek.net. The Unit 3 section would be a great place to practice and check to see if you’ve learned what you think you’ve learned. I’ll be praying for you! You can do it!
HON CHEMISTRY – So why is molecular geometry important? I mean why is knowing the correct shape of molecules? Here’s the beginning of the answer! Great job on drawing dipoles. We’ll continue our discussion on intermolecular forces tomorrow.
CHEMISTRY: Wow! There’s a ton of interesting and important stuff to know about the p block elements! To make things a bit easier for you, I’ve posted a vodcast that has all the notes on the p block in one place. Don’t forget to pay close attention to properties (physical & chemical), occurrence, and uses. (BTW – you’ll find vodcasts for the others block posted now as well!!)
As you are studying, make sure you go back and practice figuring out the period, block, group, and type of element from the electron configuration. And don’t forget the topics I asked you to research for yourself: the nitrogen cycle, arsenic poisoning – why it’s called inheritance powder, the symptoms, and the details of the Marsh test.
The videos you need to watch for the p-Block are carbon, nitrogen, oxygen, fluorine, and chlorine. http://periodicvideos.com/
Have you got the other questions from the d block elements researched and answered already? – The role of transition metals in gemstones (know colors and elements), the role of transition metals in alloys (know names, elements and uses), where the phrase “mad as a hatter” comes from, and the symptoms of mercury poisoning and why you should be careful if you eat a lot of fish! Check out the Chapter 5 Stuff to Know Sheet sheet for more.
CHEMISTRY – Hey guys, isn’t this the coolest rock? The photographer found in the desert while he was walking his dog, and when he got home he put it under UV light and it fluoresced this green color. That’s because it contains small amounts of uranium. Cool, huh!
Here’s the lecture from today on the f-Block. The videos on periodicvideos.com from the f-Block that you need to watch are slightly different from the elements that I gave you take notes on (but you may want to watch those too!): neodymium, thorium, and uranium.
CHEMISTRY: Just a deviant little group of elements, aren’t they? Did you find some interesting info when you researched these elements? Here is an old vodcast of the notes I gave one year on the d block elements – the transition metals. If you are unsure of your own notes, this vodcast might help!
Don’t forget that there are a couple of things from this block that I want you to research for yourself: the role of transition metals in gemstones (know colors and elements) and the role of transition metals in alloys (know names, elements and uses). Then I also want you to be able to tell me where the phrase “mad as a hatter” comes from and (here’s a hint!) what the symptoms of mercury poisoning are. Also, Make sure you practice writing electron configuration and using it to find period, block, group, and type of element!
Have you been watching the videos on periodicvideos.com? The elements from the d block that I especially want you to watch are copper and mercury. And there are other interesting ones you might like to watch just for fun!
PHYSICS: Great fun today! That’s the part I like – way cool applications of Bernoulli’s principle and everyday stuff that now you can explain! Don’t forget the Julius Sumner Miller Bernoulli video on YouTube if you need a refresher!
How’d you do on the preview of the problems today? Remember the concepts behind the formulas you want to use!!
HON CHEMISTRY: Dots, dots, everywhere dots!! Did the extra practice help? Here’s the work we did Tuesday (and maybe some good hints!) on drawing Lewis Structures, determining molecular geometry, and drawing ionic bonds.
PHYSICS: So were you surprised about the effect of change in surface area on the velocity of water, and especially the pressure of water, flowing through a tube? Thaaaaat explains how a calm ride on a lazy river can turn crazy in just a few seconds! Here’s the lecture from Thursday on Bernoulli – Part 1.
Today we concentrated on quantitative applications of Bernoulli’s Principle and a few practical applications. Tomorrow we’ll take a look at the problems! And to all the people involved in the play – break a leg!!
