Physics 2-21-19 Pascal’s Law

PHYSICS: Did you realize that fluids could produce that much force? Make’s you wonder at the awesome way God designed those beautiful under water sea creatures to withstand so much pressure, doesn’t it? This little creature is a lionfish from the waters of Lembeh, Indonesia.

Oh, and here’s the lecture on Pascal’s law and hydraulics and the like.

Physics 2-26-19 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…..

Hon Chemistry 2-27-19 Intro to Chemical Bonds & Covalent Bonding

HON CHEMISTRY: Hey guys, welcome to chemical bonds! Great job on using electronegativity to determine bond type. Make sure you add the scale and also the diatomic molecules to your “things I have to memorize and know how to use for the test” list.

Chemistry 2-22-19 Noble Gas Notation

CHEMISTRY – Great job with noble gas notation today!! Watch this vodcast again and it will make even more sense the second time! It would also be great review for the test! Speaking of which – have you checked out the stuff to know sheet for the test??? Super important!!!

Need extra practice or help? Wave problems? Electron configuration?? Help session this Monday, 7:20ish A.M.

Chemistry 2-21-19 Electron Configuration Notation & Blocks of the Periodic Table

CHEMISTRY: Wow! You learned a lot today! Don’t we serve an awesome God?!? You probably knew the periodic table was really organized, but did you realize that it was THAT organized? Awesome!

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 2-21-19 Chapter 5 Overview & Help Session

HON CHEMISTRY: No audio on the recording in class today, BUT I think I’ve found an old overview of Chapter 5 that will be VERY helpful. You REALLY might want to watch it as you study. Below that is the help session from this morning.

God bless you as you study! Be sure and PRACTICE. Never just look over things! PRACTICE everything!!!

Hon Chemistry 2-20-19 Electron Affinity, Ionic Radii & Electronegativity

HON CHEMISTRY: Here’s the last of the trends – not car trends, periodic trends! 2nd Ionization energy, electron affinity, ionic radii, and electronegativity – whew!!

We finished the chapter! Now to get ready for the test! A great way to begin is by watching the videos on the Periodic Table of Videos site?

In case you need the list again, the videos that you must good for review from the s-block are potassium, magnesium, and calcium.

The videos good for review for the p-Block are carbon, nitrogen, oxygen, fluorine, and chlorine.

The videos good for review for the d-Block are copper and mercury. And there are other interesting ones you might like to watch just for fun!

The videos good for review for the f-Block are: neodymium, thorium

Chemistry 2-19-19 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!

HOMEWORK UPDATE: You can hold off on #30 until tomorrow during class. You’ll do it then!
