Chemistry 1-24-20 Applications of Radioactivity

CHEMISTRY: Radioactive isotopes all around! Did you ever dream there were so many applications of radioactivity? 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 on Monday.

HOMEWORK UPDATE: Friday night’s homework (due Monday), Pg. 675, 1 – 5, 8 (Show work on all problems!!)

IMPORTANT: Don’t forget about the Half Life lab! Scroll down to find the post for your class and for more information. Data is due when? Where? Check the post and the syllabus for info!

Physics 1-24-20 Stability & Torque Problems Review

PHYSICS: Ohhhhhhhhh….so that’s how they can walk across that line! Wait – why do they keep moving their bodies?? Great opportunities for discussion and application!?!

Here’s the discussion from today on how stability relates to center of mass. At the beginning, a quick look at a couple of torque problems from the homework, Torque Worksheet 2.

Hon Chemistry 1-24-20 Chapter 4 Overview

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. BONUS – Below today’s lesson, I’ve also included a vodcast of a review day with electron notations.

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!!

Hon Chemistry 1-22-20 Electron Configuration Homework & Practice

Chemistry 1-23-20 Half Life

CHEMISTRY: Have these banana’s been through too many half lives for you?? Great job thinking through the half-life problems! Be sure and practice, practice, practice! They aren’t super difficult, but if you don’t practice, you’ll be as lost as a ball in high weeds!!

HOMEWORK FOR THURSDAY (Due Friday): Pg. 672 – 674; 21, 26 – 33, 40, 42

What about the Half Life thLab? Now may be the time to get started since next week will be a busy week! Be sure and read the lab ahead of time so you’ll be prepared with the materials you need. Also, be sure and check out the post where you’ll put your results!

7th Period Chem Half-Life Simulation Lab

Hey guys – this is where 7th Period Chemistry posts results for the Half-Life Simulation lab. You’ll just list your data from the first data table as a comment – just like you comment every week, except this time you are just listing the data from the first data table.

Don’t forget that your results must be posted by Monday, Jan. 27, by 8:00 A.M. The lab report is due by 8:00 A.M. on Friday, Jan. 31 – save as a PDF to both your Google Drive Chemistry Shared folder AND turnitin.com.

Remember, you don’t have to use candies; you may use coins or anything else that has two sides. Please note that you are to post the number of “radioactive” nuclides remaining after each toss.

Just to clarify, everything on the lab sheets will go in your lab report on that you will post on Google Drive: Title, Objective, Procedure, Observations (with data table), Conclusion, and Questions. Don’t forget that your graph needs to be either a full page graph that you do on Excel or a similar program, or you can draw a full page graph on graph paper, scan a very clean, sharp copy and copy it into your lab report. And don’t forget that the analysis questions, calculations, graph, etc., go after your conclusion.

Happy counting – and wait until AFTER the lab to snack!! πŸ™‚

Chemistry 1-20-20 Properties of Radioactive Isotopes & Radioactive Decay

CHEMISTRY: Great job today with nuclear equations! Today we finished talking about the properties of radioactive nuclides, and then it was all about types of nuclear decay and nuclear equations and arrows and where to put them! πŸ™‚

HOMEWORK UPDATE FOR THURSDAY (Due Friday): Pg. 672 – 674; 21, 26 – 33, 40, 42

So how did you do with the nuclear equations today? Make sure 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!
