Chemistry 2-28-17 Conclusion of cLAB: Element Reverse Scavenger Hunt

Posted on by

CHEMISTRY: Amazing! 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.

Click here for the link to the videos from today on Arsenic & Napoleon’s Wallpaper and The Marsh Test.

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!

Hon Chemistry 2-28-17 Dipoles & Intermolecular Forces

Posted on by

HON CHEMISTRY – So why is molecular geometry important? Here’s the beginning of the answer! Great job on drawing dipoles. And thanks for helping me pick up all that water! We’ll continue our discussion with intermolecular forces tomorrow.

Hon Chemistry 2-27-17 Ionic vs. Covalent Bonds, Pt. 2 & Metallic Bonds

Posted on by

HON CHEMISTRY: Molten iron, wow! Here’s the lecture on the rest of the notes on ionic vs. covalent bonding, followed by 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!!

Physics 2-27-17 Pascal’s Law

Posted on by

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 2-24-17 Ionic Bonding

Posted on by

HON CHEMISTRY: Hey guys, here’s the lecture on a different way that atoms come together – ionic bonding. No audio today, so I’m posting a lesson from last year.

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!

Hon Chemistry 2-21-17 Lewis Structure Practice

Posted on by

HON CHEMISTRY: More fun playing with dots!! Here’s one last look at Lewis structures, multiple bonds, and resonance before we move on to ionic bonding. Don’t forget CONS!!

Chemistry 2-21-17 History of the Periodic Table & cLAB: Element Reverse Scavenger Hunt

Posted on by

CHEMISTRY: What a great beginning to this chapter on the periodic table! This type of independent research is a great way to learn the information about the elements on the Periodic Table. Careful! Sometimes you will have to dig deep to interpret the hint from the picture!

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!!

To supplement your research, 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!

Physics 2-21-17 Archimedes’ Principle

Posted on by

PHYSICS: So when you were floating in the pool this summer, did you enjoy your fellowship with buoyant forces? 🙂 From Monday – 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 2-17-17 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! One important thing I forgot to tell you! There are only a few elements that can have a multiple bond. They are carbon, oxygen, nitrogen and sulfur – CONS. No other atoms can, so if there is ever a need for a multiple bond but you can’t have one, the compound would be an exception to the octet rule!

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!

Physics 2-16-17 Chapter 7 Conceptual Review

Posted on by

PHYSICS: So glad to have Julius Sumner Miller start our review today! Here’s the brief review we did of some of the conceptual stuff from chapter 7 – torque, circular motion, rotational dynamics, and Newton’s law of universal gravitation.

Here’s the link to Julius Sumner Miller on Centripetal Force. God bless as you study for the test – I’ll be praying for you!
