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: 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: 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: Cool thing, standing waves! Can you think of some applications of constructive and destructive interference?

HON CHEMISTRY: Great job today! Isn’t the periodic table an amazing thing? It will prove to be a very valuable tool for you! Are you starting to get the hang of using electron configuration to determine the ID of an element, and vice versa? And what about Noble gas notation? It’ll be waaaaaay easier now! Practice, practice!
CHEMISTRY: Lot of numbers today! How are you doing on writing nuclear symbols and hyphen notation – and now we added ions? Can you can now use them to determine the number of protons, neutrons, electrons, etc.?
Here’s our practice with that AND average atomic mass. 🙂

HON CHEMISTRY: Wow! You learned a lot today! Don’t we serve an awesome God?!? You probably knew the periodic table was really organized, but did you realize that it was THAT organized? Awesome!
Practice what you’ve learned!! You’ll get the hang of it and be as laid back as this “noble” fellow in no time! 😉
CHEMISTRY: Isn’t God awesome to give us minds to understand the world around us – even the parts we can’t see!
Here’s the discussion for Wednesday isotopes and how to write symbols for them. Practice!
Can you believe atoms are that small – and the nucleus even waaaaaay smaller! The thumbnail is a picture of atoms from the IBM Almaden Research Center. These are iron atoms on top of copper. Being able to move atoms around like this was a giant leap in the field of nanotechnology! (Sorry about that, bad pun! 🙂 )
PHYSICS: Here’s our lesson on the properties of waves. 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 (v = λf).
Easy peasy – and don’t forget the applications!
BONUS: Here’s a link to a NASA Launchpad video on wave motion – NASA Launchpad: Wave Motion. Since we didn’t get to play with slinkies today in person, this will be a good replacement!
HON CHEMISTRY: just when you were getting the hang of drawing arrows, I go and change it! But don’t you think writing electron configuration notation is a whole lot shorter than doing orbital notation? Don’t get me wrong, knowing how to do orbital is great for seeing how the electrons are paired, but this way is way shorter! And speaking of shorter – let’s crank it up with noble gas notation tomorrow.
HW UPDATE: Only do the regular electron configuration notation tonight. You don’t have to do the questions about noble gas notation.
Be sure and practice with the homework tonight, and don’t forget to use the Aufbau “chart”!!!!
