# Chemistry 8-24-21 Significant Figures, Pt 2 & Uncertainty

CHEMISTRY: How’d you do on the homework? Were you able to apply what you learned about sig figs?

Today we also talked about how to write uncertainty. Measuring to the correct number of sig figs and writing uncertainty will be SUPER important tomorrow when you do the lab tomorrow!

# Chemistry 8-23-21 Accuracy & Precision & Significant Figures

CHEMISTRY: I LOVE the way you are remembering and catching on to accuracy & significant figures! And how will you really unlock the puzzle of sig figs? Practice!!

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! ðŸ™‚

What about that SI Quiz Thursday? Make sure you are actively studying these things:
Everything in the SI Prefixes chart: symbol, exponent, meaning, and how many in one of a larger one. For example, 1 L is how many cL?
SI fundamental and derived quantities and their symbols
SI fundamental and derived units, their symbols, and the quantity they measure
SI standard unit for all the quantities

# Physics 8-20-21 Ch 1 Homework Review

PHYSICS: Great review of the homework from this chapter. May seem trivial now, but oh my how you’ll apply all of this for the rest of the year!

Speaking of applying – how high do you reckon that golf ball will bounce?

# Chemistry 8-20-21 Derived Units & SI Measurements, Pt 2

CHEMISTRY: Great job with derived units and fine tuning how to properly write measurements so they’ll be easily read and understood! Now on to using what you know!!

BTW – How are you doing with getting ready for the QUIZ on SI prefixes, Quantities & Units? It’s a ton of important info to know for the rest of the year. Practice, practice, practice it and don’t wait until the last minute!!

If you’re unsure of what’s going to be on the quiz or how I’ll ask the questions, go back and watch the end of this vodcast. Great overview today! Here are the topics for the SI Quiz:

Everything in the SI Prefixes chart: symbol, exponent, meaning, and how many in one of a larger one. For example, 1 L is how many cL?
SI fundamental and derived quantities and their symbols
SI fundamental and derived units, their symbols, and the quantity they measure
SI standard unit for all the quantities

# Hon Chemistry 8-20-21 Accuracy/Precision & Significant Figures

HON CHEMISTRY: Great week! And great job today remembering significant figures! Now can you go forth and apply the rules?

Speaking of remembering – how about that SI Quiz? Make sure you are actively studying these things:

# Hon Chemistry 8-19-21 SI Measurements

HON CHEMISTRY – Great job today! So is all the info on SI measurements starting to come back to you? Here’s the lecture from today – our discussion of fundamental and derived units. 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 and units? Start work on memorizing them NOW – SI quantities, units, and SI prefixes. For the prefixes, also make sure that you can tell me how many of something in the larger one. (That’s what I explained in class.)

# Chemistry 8-19-21 SI Measurements, Pt. 1

CHEMISTRY – Hey guys, so is all the info on SI measurements starting to come back to you? Here’s the lecture from today – our beginning discussion of fundamental units. 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!

HOMEWORK UPDATE: I gave you incorrect codes for The Physics classroom. Here are the correct codes below. If you already signed up, I removed you so you can sign up again:
C1 – ncschemistry12021
C2 – ncschemistry22021
C3 – ncschemistry32021
C4 – ncschemistry42021

Did you remember the prefixes and units? Start work on memorizing them NOW – SI quantities, units, and SI prefixes. For the prefixes, also make sure that you can tell me how many of something in the larger one. (That’s what I explained in class.) The quiz on them will be Thursday, August 26.

# Physics 8-18-21 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. Don’t forget to show all your work!

# Chemistry 8-17-21 Using the Scientific Method

CHEMISTRY: Great review today of the scientific method! I know you’ve heard it for umpteen years, but it is super important that you can APPLY what you’ve learned about the scientific method.

Any questions about homework? The work from the textbook can be done with the online textbook. Follow the notes I gave you in class. Do it on notebook paper, and you can use the back of the paper. Just make sure you number listing down and not across – especially if there are a, b, etc., parts – list those down on separate lines, not across the same line. Also, skip a line between each question.

Tomorrow we’ll solve the mystery of Oobleck – using the scientific method! Fun times!! ðŸ™‚

So do animals use the scientific method? Hmmm…..
