Hon Chemistry 2-15-19 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!

We’ve started a new part of the chapter! Don’t forget though that part of the first part of chapter is still important as you prepare for the test! Make sure you’ve making progress on watching the videos of elements from this chapter I mentioned earlier 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/

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 2-15-19 Bohr Model & Quantum Model of the Atom

CHEMISTRY: So which are they? Are electrons particles or are they waves? Here’s the lecture from Friday. 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.

Physics 2-12-19 Angular Momentum & Newton’s Law of Universal Gravitation, Pt. 1

PHYSICS: Wait! There’s a fourth law? Yep – Newton’s law of universal gravitation! So when you jump off of something, the Earth moves, huh?

You’ve learned little g, now you know big G! Good job setting up the formulas, also make sure you can apply the concepts.

Ready to escape? We’ll tackle the rest of the applications of this law tomorrow!

Chemistry 2-12-19 Photoelectric Effect

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 Target? And I just thought of another one, what about those automatic flush toilets!

Physics 2-11-19 Rotational Dynamics

PHYSICS – Wow! Could you do this? Here’s the lecture on rotational inertia, angular velocity, and angular momentum – rotational dynamics! We’ll pick up the conservation of angular momentum tomorrow. Fun times!

By the way – I wonder how all this applies to other rotating things…like maybe the Earth? Hmmmmm……

Physics 2-8-19 Vertical Circular Motion

PHYSICS: Great job on the vertical circular motion problems! Here’s the short lesson from today, then a look ahead at some of the upcoming circular motion problems. Fun times!! 🙂

HOMEWORK UPDATE: Add to the Circular Motion WS 2, these from the book – Pg. 264, 1 – 7, 10, 11.

Hon Chemistry 2-7-19 d & f-block Intro & a Look Back at the s-block elements

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 look at the s-block 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 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/ Go pop some popcorn and have some movie time!

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

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.

And just a heads up – the videos you need to watch for the p-Block are carbon, nitrogen, oxygen, fluorine, and chlorine. http://periodicvideos.com/

Chemistry 2-7-19 Wave Properties of Light

CHEMISTRY: Isn’t this a super cool picture of light? So tell me again, if we’re supposed to be figuring out electrons, why are we studying waves?

I’m thinking you’ve probably memorized the electromagnetic spectrum after that inspirational song; however, also sure you also know the uses of the different types (all except for long waves). Just in case you’d like to hear it again: Electromagnetic Spectrum Song

How’d you like the light problems so far? Be sure and learn the formulas, the two constants, and practice, practice, practice!

Hon Chemistry 2-4-19 History of the Periodic Table & cLAB: Element Reverse Scavenger Hunt (s-block notes)

HON CHEMISTRY: Great start to a new chapter! I love that you are going to be learning to research some really cool stuff about the elements on the Periodic Table.

Here is the intro the the history of the periodic table and and your short intro to the cLAB: Element Reverse Scavenger Hunt. We’ll pick up with the s-block tomorrow!
