Great discussion today on the Lost in the Pacific Ring of Fire project. Here’s the recording from today. If you didn’t get to come, I missed you!
HON CHEMISTRY: Great overview of chapter 6 today! Here’s our Zoom meeting – not 100% the same, but stil SOOOOO good to see you and talk with you!!
If you haven’t already, first start by getting organized. If you haven’t made one already, make a chart, a really big chart of “What I need to memorize,” “What I need to know how to do,” and “What I need to be able to apply/discuss.” Then practice the things you have have the list!! Practice is especially important on the “problem” like objectives such as Lewis structures, drawing ionic bonding, etc. I would also encourage you to make lists of possible discussion questions and then practice answering them for the test. If there are things you are unsure about, go back and watch parts of old vodcasts.
God bless you as you study! I’ll be praying for you!!

CHEMISTRY: Well that was different! But great lab today! Not as good as if you had done it yourself, but a pretty substitute. Did you hear the pop?
Here’s the video from the remote lab today. You can take screen shots from the video for your lab report. Formal lab report. Check the syllabus for the due date. Holler if you have questions!
PHYSICS: Hey guys! Here’s our discussion on the properties of waves. Remember anything from your earlier 8th grade physical science days? Problems are pretty simple for you, I think. Do you remember the main formula from chemistry? Speed = wavelength x frequency (c = λf).
Easy peasy – and don’t forget the applications!
And while you’re here, click here for the next video – NASA Launchpad: Wave Motion. Since we’re not going to be able to play with slinkies in person, this will be a good replacement!
CHEMISTRY: So you’re saying, not only are there atoms that want to get rid of electrons, there are atoms that want to take them? Here’s a picture of chlorine taking an electron from sodium – or sodium giving an electron to chlorine. I’ll let you decide!

CHEMISTRY: So what about the reasons for all the properties of the elements you studied last week? Here’s the lecture on the why – the first two periodic trends – atomic radii and ionization energy. Who knew mama ducks could help you understand chemistry!?!
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: Hey guys, here’s the lecture on the comparisons of ionic and covalent bonds – and WHY! Great stuff for application!
And whatever you do, stay away from bubble baths if you have mortal enemies!
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!
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 are the notes on the d, f, and p Block elements.
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.
To make your study of the elements even more interesting(!), there are some really great videos with tons of useful information at this site: http://periodicvideos.com/. There will be 7 videos in all: H, K, Hg, C, As, O, F. After you watch the videos, you will LIST 2 properties and 2 uses of each element. Type or hand write the answers. Convert your final document to a PDF and submit into your Google Drive Chemistry Shared Folder.
Go pop some popcorn and have some movie time!
The element from the d block that I especially want you to watch is Mercury. The elements from the p block that I especially want you to watch are Carbon, Arsenic, Oxygen, and Fluorine. And there are other interesting ones you might like to watch just for fun!
