Physics 8-23-13 Velocity Problems

PHYSICS – Here are the velocity problems from today, #11 and other homework and then some new problems. You did a great job on these! Do you see what I mean about learning to think through them?

Good luck on those next five problems. Make sure to do more than just show the math – be sure that I can also follow your logic in the formulas. Ditto with units, etc. Don’t give up on the tortoise and the hare. A couple of hints: remember the distance the tortoise travels is the same as the distance the hare travels plus the extra 20 cm he was ahead. Also, the time the hare raced is equal to the time of the tortoise minus those two minutes he rested.

Now go have fun! And have a great weekend!! 🙂

Chemistry 8-23-13 SI Measurements

CHEMISTRY – Hey guys, so is all the info on SI measurements starting to come back to you? Here’s the lecture from Friday. I’m sure it’s mostly review from your physical science days, but it’s a great opportunity to refresh what you’ve learned and to get ready to begin using it!

Did you remember the prefixes? Don’t forget to work on memorizing them this weekend, especially since I’ve changed the due date for the take home lab to next week. Here are the dates for the SI prefix quizzes: Honors Chemistry – Quiz on Wednesday; Regular Chemistry – Quiz on Thursday

I’m really of your work this week! Have a great weekend!!
