PHYSICS: Great job on the vertical circular motion problems! Here’s the short lesson from today. Fun times!!
CHEMISTRY: Wow, you did a great job today! Did quantum numbers begin making more sense when you started using them? Good work today on orbital notation. I think you’re going to be seeing arrows and numbers in your sleep!
Then, just when you were getting the hang of drawing arrows, I go and change it! But don’t you think writing electron configuration notation is a whole lot shorter than doing orbital notation? Don’t get me wrong, knowing how to do orbital is great for seeing how the electrons are paired, but this way is waaaay shorter!
Be sure and practice with the homework tonight, and don’t forget to use the Aufbau “chart” that you learned to draw last Friday!!!!
Need extra practice or help with this chapter? Help session this Thursday morning, 7:20ish A.M.
HON CHEMISTRY: Here’s the last of the trends – not car trends, periodic trends!
Now on to some serious preparations for the test!! Have you begun by watching the videos on the Periodic Table of Videos site? Great place to start!
Need extra practice or help with this chapter? Help session this Wednesday morning, 7:20ish A.M.
CHEMISTRY: Now you have the tools you need to determine where electrons are in an atom – but can you?!?
Here’s the vodcast from today on quantum numbers and the rules you’ll use to use them. Be sure and practice drawing the Aufbau Chart!! The good news – quantum numbers will begin making more sense when you started using them!
HON CHEMISTRY: Hey guys, here’s the first lecture on periodic trends – atomic radii, ionization energy, and electron affinity. You made some great connections today!
Don’t forget the element videos at periodicvideos.com. It will be a great reinforcement as you begin to study and complete your notes on the properties and uses of the elements with the information on the Chapter 5 Stuff to Know sheet. And you might just learn something along the way! It will be a great review as you start to prepare for the test. Wait – did I say test?!?
CHEMISTRY: Wow! Great job on the flame test lab – pretty cool, huh?! It’s one of my favorite labs. Did it help you understand something about how fireworks must work?
Lab reports are due by MONDAY midnight (shout out to the BB team and Honor Band!), saved to both Google Drive and turnitin.com as a PDF. It would be a very good idea for you to go back and check your graded labs in Evernote AND double check the lab manuscript form sheet to make sure your lab report is complete and in the correct format! I cannot stress that enough!! And what about your conclusion? Be sure an answer the objective, and explain how you used flame tests to identify an unknown. And don’t forget the questions at the end!
HOMEWORK UPDATE: You may omit # 30 and 31 from Friday night’s homework. Those two will be move to Monday night.
Need help or practice with the wave problems? What about a help session next week?

PHYSICS: Terrific job on the King of the Hill competition!!! I’m really proud of the work that all of you did on your cars.
It was a fierce, head to head battle with car flying all over the track, but at last the strongest car emerged victorious! Congratulations, Taylor, on being King of the Hill! Also, congrats to Ben and Austin for winning the distance and speed races! (And thanks, Lyndsey, for the photos!)
CHEMISTRY: So which are they? Are electrons particles or are they waves? Here’s the lecture from Tuesday. If you’re still having questions, you will not only want to watch this vodcast again, but also you might watch these video clips that we saw in class today – The Emission Spectrum of Hydrogen, and also this one Animated Quantum Mechanics.
Tomorrow is the Flame Test lab! Don’t forget to pre-write the lab. Check the syllabus to see what you are supposed to do.
UPDATE REMINDER: Don’t forgot the homework update! Add this to your syllabus – due Thursday: Pg. 119 – 122: 6, 9, 11, 12, 14, 15, 47, 50, 52, 53, 56 – Due Thur.
HON CHEMISTRY: Wow! Did you every dream there was that much interesting and important stuff to know about the s, p, d, and f block elements?! Here’s the final day – we ran through all the slides, clarified some information and filled in gaps you might have had.
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 that you will find on the Chapter 5 Stuff to Know Sheet on Edline!!
To make your research even more interesting(!), there are some really interesting videos with tons of useful information at this site: http://periodicvideos.com/
The videos you need to watch for the p-Block are carbon, nitrogen, oxygen, fluorine, and chlorine. http://periodicvideos.com/
PHYSICS: So is being unbalanced a bad thing? Here’s the lecture from Monday on unbalanced torques! Well, on circular motion. Lab on centripetal force and acceleration Wednesday. Prepare to duck!
But first – King of the Hill Competition tomorrow!!
