Hon Chemistry 12-5-19 Nuclear Reactors, Fission & Fusion

HON CHEMISTRY: Wow! What do you think about fission and fusion? Can you now begin to understand the destructive force of the hydrogen bomb? It’s a fusion bomb! Just another reason you might not want to plan a trip to the sun!!

We put the final touch on a lot today, and guess what? We’ve wrapped up the chapter! How are you doing on studying for the test? It will cover the beginning part of chapter 3 (through average atomic mass) and chapter 21. Did you find the Stuff to Know Sheet?

Practice everything! And did I mention, PRACTICE!! I’ll be praying for you!

Hon Chemistry 12-4-19 Applications of Radioactive Isotopes, Pt. 2 & Fission

HON 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!?

So what’s this about you probably having an radioactive isotope in your house?!? Don’t forget to research how smoke detectors, especially those with Americium, work!

Hon Chemistry Half-Life Simulation Lab

HON CHEMISTRY: Hey guys – this is where honors chemistry will post 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.

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 submit as a PDF to Google Drive and TurnItIn.com – 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™‚

Hon Chemistry 12-2-19 Half Life

HON CHEMISTRY: So what do you figure is the half-life of a banana? But I digress…. Here’s the lecture for Monday on half-life problems.

Have fun with the half-life simulation lab! Be sure and post your data in the Half Life Lab web post by the time listed on the syllabus. Don’t forget to include pics and your graph! The lab report is to be submitted as a PDF 2X by the due date listed on the syllabus. πŸ™‚

Hon Chemistry 11-22-19 Properties of Radioactive Isotopes, Pt. 2 & Radioactive Decay

HON CHEMISTRY: Can you guess what it is?/ It’s a picture of uranium ore under UV light. Cool, huh! Here’s our discussion on the rest of the properties of radioactive nuclides and the types of radioactive decay.

Great job on writing writing nuclear equations to represent radioactive decay! Don’t forget to memorize the nuclear symbols for alpha particles, beta particles (electrons), positrons, neutrons, and protons. Not nearly as bad as polyatomic ions?!?

Also, great start on half-life problems today! I love the way you were able to figure them out yourselves!! Let’s play with them some more after Thanksgiving! Calculators ready!!

Hon Chemistry 11-21-19 Intro to Radioactivity

HON CHEMISTRY: Welcome to nuclear chemistry! No, really – I think you’ll be surprised how much nuclear chemistry is already a part of your everyday life. And now you know where E=mc2 came from!!

By the way, when you get a chance, read about the life of Marie Cure – fascinating woman of science with an incredible story!

Hon Chemistry 11-19-19 Structure of the Atom

HON CHEMISTRY: Were you able to follow the connections the scientists made as they discovered the structure of the atom? Here’s the lecture from today. Do you think there could be anything smaller than protons, neutrons, and electrons? Hmmmmm……

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.

Don’t forget about the video clip we watched in class – and I’ve included a couple extra ones. they’ll help you review the different experiment that the guys like Thompson and Rutherford did. Click here for the video on the Cathode Ray Tube Experiment that Thompson did, and also for a little history on The Discovery of the Electron. Here’s the other one on The Discovery of the Nucleus.

By the way – how do you feel about playing scientist yesterday? How is what you did similar to the work of early scientists in discovering the structure of the atom?

Hon Chemistry 11-15-19 Intro to Atomic Theory

CHEMISTRY: So how do you feel about being made from earth, air, water, and fire? Here’s the intro we did on how we ended up with the atomic theory. Had you ever heard of Lavosier, Proust, and Dalton?

Pretty impressive little theory that Dalton came up with, huh? Were you surprised as you made comparisons with the Modern Atomic Theory? Could you now take it a step further and show connections between the three laws we discussed today and Dalton’s atomic theory?

Hon Chemistry 11-8-19 Polymers

HON CHEMISTRY: Oh, my word! We finally finished the chapter! Have you had a chance to check out the Chapter 7 Stuff to Know sheet?

Also amazing – did you realize molecules could be that large? And so many of them! Don’t you think polymers are some pretty unique compounds? Let’s play with them next week!

Some items for contemplation: why are certain plastics recyclable and others not…and what about dishwasher and microwave safe?
