# 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!!

# Physics 8-13-13 Measuring in Physics, continued…

PHYSICS: Did you remember sig figs? All this SI and calculations stuff will come back to you before you know it. Holler if we need to practice at a help session.

When you multiply or divide, the number in the problem with the fewest sig figs determines the number of sig figs in the answer. When you add/subtract, the number in the problem with the lowest decimal value determines the place of the last sig fig in the answer. And remember, you never go by counting numbers or conversion factors.Don’t forget to show all your work!

Now, let’s see you put it all together in the lab tomorrow! π

UPDATE – The textbooks website was down last time I checked, so I’ll move the homework to Thursday.

# Physics 8-12-13 Using Measurements in Physics, Pt. 1

PHYSICS – Hey guys, here’s part 1 of the overview we did on the SI system. 22 out of 90 slides isn’t bad, is it? π

You remembered a lot! Were you surprised at yourself? The hardest part, I think, will be getting back in the habit of showing all your work, using conversion factors, units, sig figs, etc. We’ll finish reviewing sig figs tomorrow. Happy, happy!

# Chemistry 8-25-11 SI Measurements

CHEMISTRY – Hey guys, so is all the info on SI measurements starting to come back to you? Here’s the lecture from Thursday. 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! We’ll do derived units tomorrow. And just in case I didn’t tell you, great job on your safety projects!!

# Hon Chemistry 8-23-11 SI Measurements

HON CHEMISTRY – Hey guys, great job on the Oobleck lab the other day! Ever heard of a non-Newtonian fluid? Well now you have! I posted a cool YouTube video clip of the same stuff in the VodPod below. Scroll down to the bottom right and you should see it in the VodPod collection of videos.

Soooooooo, anyway, here’s the lecture from Tuesday on the intro to SI measurements. 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! We’ll do derived units tomorrow. Good luck with your projects!!

# Physics 8-15-11 Using Measurements in Physics

PHYSICS – Hey guys, here’s an overview we did on the SI system. (You might want to pause and let it load before you play it.) You remembered a lot! Were you surprised at yourself? The hardest part, I think, will be getting back in the habit of showing all your work, using units, sig figs, etc. Hope the review over the last couple of days has helped! We’ll finish reviewing sig figs tomorrow.
