PHYSICS: So why do instruments that are playing the same note sound so different? Here’s our discussion of harmonics. (Plus another lesson on beats at the end.)
Lost in the Danakil Depression – The Last Weekend!!!
I’m praying for you as you finalize your project this weekend. I believe in you! You can do it!!!
Here are a few hints and advice – lots more great stuff is on the Final Notes & Advice sheet under the Project tab!
1. Make sure you internally document everything! That includes anything you talk about. Also, make sure your illustrations have an internal documentation typed/written on them. (Yes, you have to have illustrations! If you don’t something’s wrong.)
2. As a chemist, you must talk about all 23 items – why they would be good to use or why you would not want to use them. NEVER say you had no use for the item. You will not get credit if you do.
3. Don’t wait to do your Works Cited page last. Do it before you finish the final draft of your paper. It takes a while to compile a Works Cited and if you don’t have one, I cannot accept your paper. It would be better to have a few mistakes in your paper than to not turn in a Works Cited.
4. Save as you go! Go ahead and save a copy of your latest rough draft in your Shared folder – label it rough draft for now. This way, if something happens in your drive or if your computer crashes at the last minute, I’ll be able to see that you have been working on your paper.
5. Get someone that you trust to read over your paper and check it against the project guideline sheet that I gave you – especially the Manuscript Form Checklist. They’ll be able to help you find things you might have left off.
You can do great things! I believe in you and I can’t wait to read your paper!

Chemistry 4-11-24 Types of Radioactive Decay
CHEMISTRY: Today has been all about arrows – well, sideways arrow! So how are you doing with the nuclear equations? Feeling better about them now that you know what side of the arrow to put the particle on? Also, make sure you memorize the nuclear symbols for alpha particles, beta particles (electrons), positrons, neutrons, and protons – those are just as important as the arrow!

Physics 4-11-24 Resonance Applications & Beats
PHYSICS: Here’s our look at some applications of resonance. And to finish things off – getting down and dirty with Beats! Well, not really, but how fun are beats!?!

Chemistry 4-10-24 Properties of Radioactive Isotopes
CHEMISTRY: So ordinarily it looks like just any old hunk of rock, but this is a picture of uranium ore under UV light. Pretty cool, huh?!? Here’s our beginning discussion of the unique properties of radioactive nuclides. And as a bonus, this vodcast has a head start at looking at nuclear equations. Woohoo!!
Below the lesson vodcast is a look at some of the homework questions involving binding energy, neutron to proton ratio and nuclear stability – #48, 9, 10, and 11. These would make great test discussion/problems! Be sure and distinguish between light and heavy isotopes!

Physics 4-10-24 Sound Intensity and Resonance
PHYSICS: All kinds of ways to make music! And great discussion of intensity and resonance! Were you okay with the problems?
Couple of items to apply for further contemplation – so how does the whole hearing thing work? I mean, I know the little bones in your ear move, but why? Is resonance involved? Great item for application/discussion!
Chemistry 4-9-24 Intro to Radioactivity
CHEMISTRY: Great start to a new chapter! I think you’ll be surprised how much nuclear chemistry is already a part of your everyday life. Also now you know where E=mc2 came from!!
By the way, you ought to read about the life of Marie Cure when you get a chance. Fascinating woman of science with an incredible story!
Physics 4-9-24 Sound
PHYSICS: So you can see sound?! Here’s the lecture from today – some wave stuff, echolocation, speed of sound, …. Too much fun!!
Also, here’s the link to the video we watched today on shock waves, supersonic flight and sonic booms: Supersonic Flight & Sonic Booms
Hon Chemistry 4-5-24 Chapter 4 Overview
HON CHEMISTRY: Are you ready for the chapter 4 test? Here’s an 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 4-5-24 Wave Interference
PHYSICS: Cool thing, standing waves! Can you think of some applications of constructive and destructive interference?
