SBEC Chemistry and Physics

Okay, so maybe Sudoku (scroll below) isn’t your thing… Click to start and give it a second to load. How are those memory skills?

How about a little Sudoku to keep your brain sharp?

Another way to exercise a different part of your brain this summer… Okay, this is really simple, but what’s your best time? Watch out, it’s addictive!

Have a wonderful summer! How about a little brain exercise? Click and drag to play…

Well, it’s almost over - can you believe it?!? Seems just like yesterday you were coming into my chemistry class for the first time, learning to light a Bunsen burner. Aaaaahh, good times! So what was the best, what was the worst? Careful now, I’m still grading your papers!
Here’s one for the memory books. Will you ever forget what desiccated water is?

Can you believe it! Here’s the last lecture from Chemistry 08-09! Just a brief overview of fission and fusion.

Good luck studying for the laaaaaaaaaast chapter test of the year! I’ll be praying for you!! Did you think the day would ever come! Be careful and don’t take the test for granted. Make sure you practice half-life problems and nuclear equations. Also, make sure you’ve memorize the nuclear symbols for alpha particles, beta particles, positrons, neutrons, and protons. And then there are tons of notes on the conceptual stuff. Properties of radioactivity, people, types of radioactive decay, applications of radioactivity, definitions, definitions, and definitions! Practice! And did I mention, PRACTICE!!

CHEMISTRY: So it turns out there are some pretty useful applications of radioactivity! Here’s the lecture from Friday. Don’t forget that, in addition to the homework on the syllabus, don’t forget to identify the terms associated with a nuclear reactor: fuel, containment structure, moderator, control rods, coolant. Have a great weekend!

So how did you like half-life problems? Think them through - you can do it!! Here’s the vodcast from Wednesday. NO AUDIO! Let it load all the way, then fast forward to where I write out the problems, if you need help. Sorry about that - I think we’ve got us some gremlins! Or maybe just a chemistry teacher who can’t figure out the correct settings for the mic. Myself, I’m voting gremlins!

Here’s a pic of uranium ore under UV light. Cool, huh! Here’s the lecture from Tuesday on the types of radioactive decay. It also includes how to write nuclear equations. Don’t forget to memorize the nuclear symbols for alpha particles, beta particles (electrons), positrons, neutrons, and protons. Aren’t you glad there aren’t 17 types of nuclear equations?!?
