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 12-3-18 Radioactive Decay & 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 radioactive decay – nuclear equations and half-life problems.

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, huh?!? And great job on half-life problems today! I love the way you were able to figure them out yourselves!! Keep thinking these problems through – listen to the story they’re trying to tell you, and you’ll do great.

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™‚

Chemistry 12-3-18 Molecular Formulas

CHEMISTRY: Hey guys! Awesome job with empirical formulas, and now you’ve conquered writing molecular formulas! Here’s the lecture from Monday. It’s just like writing empirical formulas but with a twist at the end!

We are getting very close to the end of the chapter! Homework for tomorrow night (Tuesday) will be the online practice test in PowerSchool learning. Make sure you are logged in as you, and then go to the calendar and you should see it there. It’s also on the Chemistry page – holler if you can’t find it.

Have you started preparing for the test? It will be over ALL of chapter – plus the small bit from chapter 3. Be sure and checked out the Stuff to Know sheet for all of chapter 7 on Edline!

By the way, if you’d like some practice or if you have questions, help session Wednesday morning, 7:20ish A.M.!

Physics 12-3-18 Simple Machines

PHYSICS: Did you remember this stuff on simple machines from your physical science days? I don’t think you’ll have any trouble with efficiency and mechanical advantage problems. Give them a whirl and let me know!

UPDATE: Help session from Monday is posted below.

How do you think the efficiencies of machines compare? Could you design a method to test that? You don’t need no stinkin’ lab sheets! Do you? πŸ˜‰

Speaking of labs – Payne wants me to remind everyone that the questions you need to answer for the Capstone lab are the ones at the very end – I believe they are called Analysis and Summary questions.

Help session from Monday

Physics 11-30-18 Conceptual Review – Work, Consv. of Energy . . .

PHYSICS: Here’s our conceptual look at work and energy from Friday – and our big discussion of problem #21 – the diver off a diving board.

How are you doing with the big mama problems? If you need some help, below, there’s a look at – problems #22 – circus monkey on the incline, #21 – diver steps off a diving board, and a preview of #46 – a skier is pulled up a slope. Below that is a look at the rest of 46 and #47. How are you doing?

Help Session Monday morning, 7:20ish A.M.

…and from today’s class:
