CHEMISTRY – Here’s our really short second look at percent error problems, and also uncertainty. Keep that formula handy!
Hey are you studying for the SI quiz?!! Super important – you’ll use that stuff all year long!
Also, how’s the Scavenger hunt going? Did you notice the deadline? Make double sure you give yourself plenty of time!!
PHYSICS – What “moving” lessons from yesterday and today! Get it? “Moving”? Okay, okay, I’ll stop.
You did a great job with your own “intro to motion” – great job and great beginning to kinematics today!
Let’s crank it up on the problems tomorrow!
Part 1 (From Wednesday)
Part 2: (From Thursday)

CHEMISTRY – So you think Goodman Road is getting crowded? How’s this for a “high density” city? Great work with derived units today. Now on to accuracy and precision. Can you apply what you’ve learned? Hmmmmm………
CHEMISTRY – Hey guys, so is all the info on SI measurements starting to come back to you? Here’s the lecture from today. 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.) The quiz on them will be next Wednesday, August 29.
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.
Speaking of that, you’ll have a great chance to practice using the scientific method tomorrow with Ooblek! Make sure you print and read the Oobleck lab sheet and bring it to class tomorrow!
And speaking of homework – the work from the textbook can be done with the online textbook. 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. Be sure and turn it in at the beginning of class tomorrow.
So do animals use the scientific method? Hmmm…..

PHYSICS: Are you? A hoarder, I mean? I soooooo don’t want you to be that person that has a million facts crammed in their head, none of which are useful for anything because you can’t apply what you know. Let’s tackle that this year!
Here the last of the review from your old chemistry days – a short look at analyzing data. Speaking of that, how are your “Excel” graphs coming along? Any questions?
Happy Thursday! Are you having a knowing where to post your web post comment or understanding what a good web post comment is? In the future, you will probably be taking online classes where you will have to be part of online class discussion groups, and you’ll be graded on your comments and how you participate.
Here is a plan that will help you! Your goal is to have STAR Web Post Comments. Hokey title, but maybe it will stick! Click here on the STAR Web Post Comments Idea Sheet under the Worksheets/Handouts tab for ideas for good comments that will receive credit.
Here are some hints:
IMPORTANT: Make double dog sure you write your name in your web post the correct way. If your name/heading is not written correctly, you will not receive any credit for making the web post. Check an earlier syllabus for instructions on how to write your name.
Here’s what you do to post a web post comment:
CHEMISTRY: Great job with filtering and evaporating today, and great job in lab this week! Wow – you’ve learned a lot!! God bless you as you finish up studying for tomorrow’s test!
Did you read the review post earlier? Here’s the info again. In addition to the lab safety packets and the lab safety video, this is some VERY IMPORTANT information to study
HUGE HINT: Go back and view the earlier posts/slide shows on Lab Apparatus, Lab Tour, Lighting a Bunsen burner, Measuring Mass and Volume, etc. All of these are VERY helpful for the test!!
Also, don’t forget that the entire Exp: Lab Procedures & Techniques packet (including observations for ALL of the procedures you did as well as ALL of the questions on pages 13 – 18) is due TOMORROW.
God bless you as you study! It’s a ton of information, but you can do it!! I’ll be praying for you!!

CHEMISTRY: Did you remember about massing with a balance and measuring volume with a graduated cylinder?
If you need a quick tutorial, here are some of the tips from today – some reminders on how to read the instruments and how far out you carry your measurements, etc.
Both the mass and volume measurements are due by Friday. I’ll be at school by 7:45 if, you’d need to come finish up. Also, don’t forget the tons of questions at the end of the packet!

CHEMISTRY – Great job lighting Bunsen burners today! By the way, did you happen to see a green flame when you put the copper wire in the flame? The electrons in the copper atoms were being excited and they gave off a green flame. Cool!!
Here’s something you will find useful in the future…everything you wanted to know about a Bunsen burner and how to light it. View the slide show BEFORE you take turn in your lab sheets and take the test.
Tomorrow we’ll continue with Parts 4 & 5. Be sure and read ahead before you come to class! Also, make double dog sure you are keeping up with the observations and answering ALL of the questions at the end of the lab on pg. 13 – 18. There are a TON of them!!!
