Physics 2-29-16 Bernoulli – Part 2 . . . & Part 1 Again

Posted on by

PHYSICS: Great job with Bernoulli today – but no audio, so here are a couple of lessons from the past!

The first vodcast below has the lesson on Bernoulli Part 1 again. (Static at the beginning, but it clears up at about 3 minutes.) In it we mainly concentrate on quantitative applications of Bernoulli’s Principle and a few practical applications. Here’s Julius Sumner Miller Bernoulli video on YouTube if you missed him in class!

The second vodcast below is a peek into the Bernoulli problems – Bernoulli Part 2. My best hint – Remember the concepts behind the formulas you want to use!!

Hon Chemistry 2-29-16 Dipoles

Posted on by

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 with intermolecular forces tomorrow.

Chemistry 2-29-16 Conclusion of cLAB: Element Reverse Scavenger Hunt

Posted on by

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 a final run through all the slides, clarifing some information and filling in gaps you might have.

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/

Some great videos to watch from the s-block for the test are potassium, magnesium, and calcium.

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

Some great videos to watch from the d block are: copper and mercury. And there are other interesting ones you might like to watch just for fun!

Some great videos to watch from the f block are: neodymium, thorium, and uranium. Go pop some popcorn and have some movie time!

Chemistry 2-26-16 History of the Periodic Table & cLAB: Element Reverse Scavenger Hunt

Posted on by

CHEMISTRY: What a great beginning (and almost end!) to this chapter on the periodic table! How did you like this way of learning the information about the elements on the Periodic Table? I loved watching you learn to research some really cool stuff about the elements.

Here is the intro the the history of the periodic table and and intro the cLAB: Element Reverse Scavenger Hunt that we did when we very first began the chapter. In addition, I’ve spliced the brief intro notes that I gave you for each block onto this one vodcast. At the very end there is a question/answer session from one of the classes about some of the items in the cLAB.

On Monday I’ll give you a chance to go through the Element Reverse Scavenger Hunt before you turn it in and ask me about any of the elements/clues you might have questions about!

As you are studying for this chapter, make sure you go back and practice figuring out the period, block, group, and type of element from the electron configuration. Also, don’t forget the Chapter 5 Stuff to Know Sheet on Edline!!

Physics 2-26-16 Bernoulli – Part 1

Posted on by

PHYSICS: Were you amazed at 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 is the lesson from Friday – Bernoulli Part 1. We mainly concentrated on quantitative applications of Bernoulli’s Principle and a few practical applications. More of the latter on Monday!

HOMEWORK UPDATE: Do Thursday’s homework – Pg. 289: 17 – 21 and Bernoulli Worksheet

Hon Chemistry 2-26-16 Metallic Bonds

Posted on by

HON CHEMISTRY: Molten iron, wow! Here’s the lecture for Friday on the rest of the notes on metallic bonding.

Aren’t you glad there are no structures to draw for metallic bonds?! Make sure you can use the electron sea model to explain the properties of metals. Also be able to compare and contrast all three types of bonds.

Have you made your own Chapter 6 “Stuff to Know Sheet”? Great way to get organized as you get ready for this test on Friday!!

Hon Chemistry 2-25-16 Ionic Bonding

Posted on by

HON CHEMISTRY: Hey guys, here’s the lecture for Thursday on a different way that atoms come together – ionic bonding.

Keep in mind that when you write ionic bonding, you’re not trying to arrange a single structure like you do with Lewis structures. Instead, you’re writing an equation that shows electrons being lost by one atom and gained by another atom. And make sure you put the dots in the right order!

Also important, pay close attention to the comparisons of ionic and covalent bonds – and WHY! And whatever you do, stay away from bubble baths if you have mortal enemies!

Physics 2-22-16 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.

Hon Chemistry 2-22-16 Resonance & Polyatomic Ions & Molecular Geometry

Posted on by

HON CHEMISTRY: Who knew we’d be doing geometry in chemistry?!? You did a great job today! Lewis structures, multiple bonds, resonance, and now polyatomic ions and molecular geometry – wow, that’s a lot you’ve conquered in the last few days!

Molecular geometry is super easy. Make sure you know how to draw Lewis structures, then determine the type of ABE structure and you’ve got it. Here’s a copy of Molecular Geometry Shapes – VSEPR handout. Be sure and memorize the shape and the ABE structure that goes with it. Easy-peazy!

Here’s some good advice – don’t take shortcuts. Learn the proper steps on the easier molecules, and you’ll be able to do the hard ones. And if it’s still all Greek to you, don’t worry! Keep practicing and you’ll get it, I promise!! Don’t forget to count electrons and don’t forget CONS!
