Chemistry 8-28-20 Significant Figures & Calculations

CHEMISTRY: Happy Friday! I wonder how you do sig figs if you’re calculating on an abacus?!

So today you learned how far to carry out answers when you’re working problems. Here’s our discussion from today – using significant figures in calculations.

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!
