Hon Chemistry 4-3-23 Chapter 4 Overview

Posted on by

HON CHEMISTRY: God bless as you study for the chapter 4 test! Here’s our overview of the test and look back at some of the “problems” from the chapter.

Have you checked out the Chapter 4 Stuff to Know Sheet? Make sure you give yourself plenty of time to memorize the things you need to memorize so that you can apply them on the test. And practice, practice, practice, the problems and electron configurations. Did I mention that already?

What about applications for discussion? Photoelectric effect, spectroscopy, etc.? Another great idea for studying is to watch the videos that we watched in class, and others – super helpful as you study for the test!! Here are some of them:
Spectrum of the Stars (overivew of the results of the spectroscopy lab you did, shows the connection between our lab on spectroscopy and how we can identify elements), Emission Spectrum of Hydrogen (how we use it to know about the energy levels in an atom), Quantum Mechanics (about the roles of Bohr, Schrodinger, Heisenberg), and also Animated Quantum Mechanics.

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

Physics 4-3-23 Properties of Waves

Posted on by

PHYSICS: Today’s lesson is three parts. First you’ll watch a short vodcast on the properties of waves and then a short NASA video on wave motion (link is below) since we won’t be able to place with slinkies today in person. To wrap it up and make sure you have the concepts nailed down, there are three activities from the The Physics Classroom that you’ll do.

1) Vodcast – view below
2) NASA Launchpad video on wave motion – NASA Launchpad: Wave Motion.
3) Either your book HW for tonight or The Physics Classroom Activities – Concept Builders: Wave Basics, Wave Cases and Concept Checkers: Simple Wave Simulator (either mode is okay)

Do you 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!

Chemistry 4-3-23 Structure of the Atom

Posted on by

CHEMISTRY – Chocolate chip cookie dough model of the atom? That’s what Thompson thought the atom must look like! Here’s our discussion of how scientists began to determine the structure of the atom and the existence of subatomic particles.

For each, make sure you know the name of the scientists, the name of their experiments, be able to draw a diagram of their experiment, and describe how they interpreted the experimental results that led to their discoveries. Wow, that’s a mouthful!

As we continue the explore the discovery of the structure of the atom, here are some video clips that I want everyone to watch that will help make things a bit clearer. Click here for the video on the Cathode Ray Tube Experiment that Thompson did, and also for the video clips that I want you to watch on The Discovery of the Electron and The Discovery of the Nucleus. All of these will be great tools in studying for the test!
