Physics 2-20-18 Archimedes’ Principle

PHYSICS: So when you were floating in the pool this summer, did you enjoy your fellowship with buoyant forces? 🙂 From Tuesday – Archimedes’ Principle.

Great topic for investigation! Speaking of which – what did you find? When the kid jumped out of the boat, did the water level rise, fall, or stay the same? Hmmmm…..

Chemistry 2-15-18 Orbital Notation & Electron Configuration Notation

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”!!!!

Need extra practice or help with this chapter? Ask me about a help session next week!

Hon Chemistry 2-15-18 d & f-block Intro & a Look Back at cLAB: Element Reverse Scavenger Hunt

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 introduction to the d & f blocks, and then, our beginning of running through all the slides to clarify 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 (coming very soon!!)!

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 that you must watch from the s-block for the test are potassium, magnesium, and calcium.

The videos you need to watch for the p-Block are carbon, nitrogen, oxygen, fluorine, and chlorine. http://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!

The videos on from the f-Block that you need to watch are: neodymium, thorium, and uranium. Go pop some popcorn and have some movie time!

Chemistry 2-14-18 Quantum Numbers

CHEMISTRY: See what Bohr and Heisenberg’s work led to? 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!

Chemistry 2-12-18 Bohr Model & Quantum Model of the Atom

CHEMISTRY: So which are they? Are electrons particles or are they waves? Here’s the lecture for Monday. 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 Emission Spectra of Atoms lab! Don’t forget to print the lab and read it BEFORE you come to class!

Physics 2-9-18 Rotational Dynamics

PHYSICS – Wow! Could you do this? Here’s the lecture on rotational inertia, angular velocity, and angular momentum – rotational dynamics! By the way – I wonder how all this applies to other rotating things…like maybe the Earth? Hmmmmm……

Chemistry 2-8-18 Photoelectric Effect & Wave Problems

CHEMISTRY: Fun field trip today!! Good job coming up with examples of the photoelectric effect. What? There really aren’t tiny people living in boxes above the doors at Wal-mart? And I just thought of another one, what about those automatic flush toilets!

What did you think about the energy problems? Again, make sure you not only memorize formulas, but also be careful to learn the symbols and units for each of the quantities you’re going to use, it’s easy to get them confused!

Need practice? What about a help session?

Hon Chemistry 2-8-17 Electron Affinity, Ionic Radii & Electronegativity

HON CHEMISTRY: Here’s the last of the trends – not car trends, periodic trends! For now, it’s an lesson from last year, so fast forward past the syllabus part! 😉

Have you begun by watching the videos on the Periodic Table of Videos site? Great place to gather information for the cLAB!

The videos that you must watch from the s-block are potassium, magnesium, and calcium.

The videos you need to watch for the p-Block are carbon, nitrogen, oxygen, fluorine, and chlorine. http://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!

Hon Chemistry 2-7-18 Atomic Radii & Ionization Energy

HON CHEMISTRY: Hey guys, here’s the first lecture on periodic trends – atomic radii and ionization energy. You made some great connections today!

If you’d like to get a head start on the element videos that I talked about in class today, they are at periodicvideos.com. Very interesting(!), with tons of useful information!

The videos that you must watch from the s-block for the test are potassium, magnesium, and calcium.

The videos you need to watch for the p-Block are carbon, nitrogen, oxygen, fluorine, and chlorine. http://periodicvideos.com/
