PHYSICS: Great job thinking through the problems today!
Remember a few things: You weren’t born knowing how to do these – give yourself a little time. On the really good ones, 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! Some good advice – go work them again! I promise, it will be good for you. Remember, don’t open the solutions you wrote in your notes! Try them without it!! If you have to, peek, but then don’t stop until you can work the entire problem through without looking!

CHEMISTRY – Here’s our look at expressing accuracy with percent error and uncertainty. Keep that formula handy! We also began looking at significant figures today. Did you remember them? Use them and you will!
Two super important things: Make sure you are actively studying for the SI quiz! Also super important – keep up with your homework!! The reason I give it to you so you can practice and put together all we talked about in class ….cuz I love you! 🙂
Be sure and check your syllabus!!

HON CHEMISTRY: Can estimate out how fast you can drive in at least one parking lot in Guatemala – and can you show me how you solved the problem? Even better, can I trust the validity of your work?
Good job on remembering how to use conversion factors! Remember, this isn’t just about getting an answer – some of you can do that in your head. This is about being able to convert from one unit to another using the Q-formula. (And yes, you have to do it that way!)
