CHEMISTRY: Radioactive isotopes all around! Did you ever dream there were so many applications of radioactivity? Thanks for the great job on adding to the lecture! This is a pic of a test used to check on blood flow through the heart during a stress test. Fun, huh!? Click on the link below the pic to learn more from Cedars-Sinai hospital.

Here’s the lecture from today – applications of radioactive isotopes. We’ll finish more applications and then fission and fusion tomorrow. Have you checked out the Chapter 21 Stuff to Know & Study Suggestions sheet on Edline? Help session will be Wednesday morning, 7:20ish A.M.

IMPORTANT: Don’t forget about the Half Life lab! Data is due when? Where? check the syllabus for info!

HON CHEMISTRY: God bless as you study for the chapter 4 test! We had no audio today, so I’m posting an overview from last year.

Have you checked out the Chapter 4 Stuff to Know Sheet from Edline? 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 – 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!!
