HON CHEMISTRY: Wow! Did you realize radiation was everywhere? It turns out there are some pretty useful applications of radioactivity! Let’s finish talking about that tomorrow.

Hon Chemistry 2-10-25 Radioactive Decay & Half Life
HON CHEMISTRY: How’d you like writing writing nuclear equations to represent radioactive decay? Maybe a tad bit easier than writing chemical equations? 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?!?
Great discussion of half life! Do you need a formula for the problems or can you think through them?

Physics 2-10-25 Conical Pendulum & Banked Turns
PHYSICS: More going around in circles, but this time with a twist. Here’s our discussion of conical pendulums and banked turns.

Chemistry 2-10-25 Stoichiometry
CHEMISTRY: Wow!! Great job today with stoichiometry!! Now it’s time to put everything you’ve learned from the last few chapters together. It’s like cooking – figuring out what you need to get what you want. Slightly different ingredients, though. Don’t forget molar mass and mole ratio!
HW INFO – To find the pages for tonight’s homework, either go the the Textbook HW Tab and you’ll find the pages there. Also you can go to the online textbook, open the chapter, and then in the section where you can enter page numbers, enter R109. Either of these will take you to the pages for tonight’s homework.

Hon Chemistry 2-6-25 Properties of Radioactive Isotopes
HON 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!!
Physics 2-6-25 Vertical Circular Motion
PHYSICS: So would you ride a roller coaster without a seat belt? Here’s our discussion of vertical circular motion. Fun times!! 🙂

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!! 🙂
Physics 2-5-25 Circular Motion
PHYSICS: Wonderful visual today of the difference in angular speed and linear speed! Thanks for playing along!!
So is being unbalanced a bad thing? Here’s the beginning discussion of circular motion.
Hon Chemistry 2-5-25 Intro to Radioactivity
HON CHEMISTRY: Recognize this symbol?! 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 Curie – fascinating woman of science with an incredible story!
