Chemistry 10-31-11 Moles, Mass, Atoms Problems Practice

CHEMISTRY – So, how big a bucket do you think we’d need for a mole of candy corn? Yum! πŸ™‚ Here’s the short review we did on the mole, mass, atoms problems. Did it help? Just don’t forget the conversion factor, and think through the problems. Put units first and then numbers. Make sure what you’re doing has a reason and makes sense!

Hon Chemistry 10-18-11 Using Chemical Formulas – Moles & Mass

HON CHEMISTRY: Good job using chemical formulas as tools today! So it turns out there are tons of ways that you can use them. Like finding molar mass, moles, and molecules! Did it all sound familiar to you – like we were repeating yesterday’s lecture? Here’s the lecture from Tuesday.

Chemistry 9-20-11 Intro to Chemistry

CHEMISTRY: We’re finally starting what chemistry is all about! Here’s the lecture from Tuesday on the intro to chemistry. Good job making applications with the branches of chemistry and types of scientific work! Make sure you have the vocab down, and be sure you’re able to apply what you learned today. Can you tell the difference between quantitative and qualitative, intensive and extensive properties, physical and chemical changes, etc.? Can you give me examples?

BTW – Have you started learning the symbols of the elements? Is that something you’ve had to do in your other classes? Don’t forget to check out the earlier webpost on quizlet.com. It’s a great way to begin memorizing them! πŸ™‚

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!!
