Physics 8-29-11 … and the Tortoise & the Hare

PHYSICS: Just in case you need it, here is the solution to the tortoise and the hare problems – # 21 & 22. Remember a few things: You weren’t born knowing how to do these – give yourself a little time. Just one formula won’t work – begin with writing what your know. These are some of the hardest problems we’ll work in physics – not because the formulas are hard, but because knowing how to reason through them is so challenging. You are doing a great job! BYW – Don’t open the solution to number 7! Try it without it!!

Tomorrow I’ll give you a break – we’ll start acceleration. I think you’ll find that it’s a whole lot simpler – all you have to do is practice using some formulas! Did you hear what I said? Formulas!! 🙂 Not simple mind you, but you’ll be surprised how much you’ve already learned. I’m proud of you!!

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!!
