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 12-3-14 Problems Review – Machines, Work, Consv. of Energy . . .

PHYSICS: So it’s official – the test will be Friday, and the machines lab will be moved to next Monday. The first vodcast below is the review of the problems from today’s help session (#46 – crate pulled up the incline from the machines homework and #47 – ski acrobat from chapter 5). Below that are the problems we did in class (#22 – circus monkey on the incline, #21 – diver steps off a diving board, and #46 – a skier is pulled up a slope).

Hon Chemistry 12-3-14 Applications of Radioactivity, Pt. 1

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.

Chemistry 12-3-14 Dalton & the Modern Atomic Theory

CHEMISTRY: Change in plans!! Watch the vodcast from today for the change in homework! You can also use the vodcast to get the parts of the Modern Atomic Theory if you didn’t get it in class today.

How hard do you think it was for scientist to figure out what exactly atoms are and what they might be made of? We’ll check that out tomorrow! Don’t forget your sock, can, and items! Watch today’s vodcast or go back to yesterday’s web post if you have questions about what to bring tomorrow.
