Chemistry – Chapter 5 Test Overview for 4/6 – 8/20

CHEMISTRY: Well, the overview for this test is a little different. I recorded it outside! It’s in two parts. It will be kind of like going to a help session on my front porch 🙂

Speaking of studying for the test, make sure you’ve taken a very good look at the updated Chapter 5 Stuff to Know Sheet!

God bless you as you study! I’ll be praying for you!!

Part 1

Part 2

Physics – Wave Interactions for 4/6 – 9/20

PHYSICS: Cool thing, standing waves! We won’t get to make waves with slinkies together, but you’ll get a chance to simulate it in the simLAB: Waves on a String! Are you okay with constructive and destructive interference?

Here’s the lesson on wave interactions. Can you think of some important applications?!

Hon Chemistry Ch 6 Test Overview 4-2-20

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 – Remote LAB: Periodic Trends & Properties of Metals

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 – Waves (for 3/30 – 4/3/20)

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 – 2nd IE, Electron Affinity, Ionic Radii & Electronegativity for 3/30 – 4/3/20

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 Atomic Radii & Ionization Energy for 3/30 – 4/3/20

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 – 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!!
