Hon Chemistry – Metallic Bonds (for 3/30 – 4/3/20)

HON CHEMISTRY: Molten iron, wow! Here’s the very short lecture 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!!

Hon Chemistry – Ionic Bonds (for 3/30 – 4/3/20)

HON CHEMISTRY: Hey guys, here’s the lecture 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!

Isn’t this a beautiful crystal of copper sulfate pentahydrate? Since we’ve been talking about crystal lattice structures, I thought you might like to see something different than salt!

Hon Chemistry – Dipoles for (3/23 – 30/20)

HON CHEMISTRY – So why is molecular geometry important? What’s the big deal about knowing the correct shape of molecules? Here’s the beginning of the answer! Great discussion and great job on drawing dipoles. We’ll continue with intermolecular forces in the next vodcast.

Chemistry & Honors Chemistry – Exploring Remote Learning

CHEMISTRY: Welcome back! I’ve missed you guys!! This new way of learning is going to be a tad awkward for a while, but remember how you eat an elephant…! We’ll gradually build and add new aspects to what we do – lessons via vodcasts and hopefully very soon, video conferencing with the class. For now, though, baby steps! Be sure and explore the Remote Learning Page in your Chemistry page in PowerSchool.

Here’s where you begin. Go the Chemistry Page in PowerSchool Learning. Explore the Remote Learning Page and get comfortable with where everything is (especially the Discussion Board!)

  • Read the “What We’re Doing” block
  • Read the “Daily Expectations” block
  • Find the Discussion Board Tab
  • Let me know if you have any questions!

Now for the written part. Go to the Discussion Board in the Chemistry Page on PowerSchool Learning and enter the following in the Lost… Project Discussion Board:

  1. What is your biggest difficulty with the project?
  2. What question(s) do you have about the project?

FYI – There will be some changes to the project that I’ll let you know about very soon. For example, you are now going to be allowed to use eBooks as your book sources.

I’ll put the new project details on the class website as soon as I have everything finalized.

The web post topic for this week: Challenge. What’s been your biggest challenge in the last seven days (personal life or school life)? What are you doing to try face it?
(Let me know at some point what you think about this new deadline for web posts. Good? Bad? No opinion?)

This is going to be a great day!!

Lost in the Pacific Ring of Fire

Welcome to a great adventure! You’ve learned so much this year – not just concepts, but skills, and you’re still learning! I can’t wait to see how you are going to apply it all!

Here’s the place where you can post your questions about the “Lost…”. First answer – the due date is Wednesday, April 15.

A really useful hint? Go back and re-read the project again – this time with a highlighter. It’s amazing how much I miss the first time I read something. So what’s your next question?

Here’s another copy of the whole project, if you need it:

Hon Chemistry 3-2-20 Molecular Geometry Homework & cLAB

HON CHEMISTRY: Good job with Lewis structures and molecular geometry! Below is the very brief look at the homework we went over today. Holler if you decide we need to take a longer look, and we can schedule a help session.

Also we began the cLAB: 3D molecules today in class, and this vodcast will give you a head start on that assignment. Be sure and read the lab sheet BEFORE you get too far and especially before you turn in the assignment!!

Hon Chemistry 2-28-20 Resonance & Polyatomic Ions & Molecular Geometry

HON CHEMISTRY: Who knew we’d be doing geometry in chemistry?!? Great job today! Lewis structures, multiple bonds, and now resonance, 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!

Honors Chemistry 2-27-20 Lewis Structures & Multiple Bonds

HON CHEMISTRY – I just love dots! Incredible job today with Lewis structures!! If you were absent, be sure and watch this vodcast for some great hints on making Lewis structures easier. And make sure you practice, practice, practice! Warning: before you know it, you’ll be seeing dots everywhere!
