Chemistry 8-25-16 Using the Scientific Method, Pt. 2

CHEMISTRY – Great fun with Oobleck today! Were you successful in using the scientific method? Here is the rest of lecture from today on using the scientific method.

CAUTION: Be sure and read the questions on the Oobleck sheet VERY carefully as you answer! Lab sheets are due tomorrow in class.

Physics 8-25-16 Motion and Displacement

PHYSICS – What “moving” lessons yesterday and today! Get it? “Moving”? Okay, okay, I’ll stop.

You did a great job with your own “intro to motion” yesterday – great job and great beginning to kinematics today! I gave you the wrong word in class – did you notice!? I said them opposite! Kinematics, not dynamics is the study of motion without consideration of its cause.

Let’s crank it up on the problems tomorrow!

Physics – Human Density Lab

PHYSICS: Just another day in the life of a physics student! Who knew water displacement could be so much fun! :) Thanks Hannah!! Good job moppers, and fillers, and counters, and recorders! Now for the lab report. Remember to include that final question in your conclusion – “So why can or can’t some humans float?” And don’t forget – I’m very, very interested in your experimental design, i. e., how’d you gather your data, how are you presenting your data, sig figs, calculations, etc.

Speaking of labs – I’m looking forward to seeing how close you came to predicting the height of the bouncing ball! Can I trust the validity of your prediction?

Water, water, everywhere! I’ve posted some pics on flickr – click here or below for the link.

Chemistry 8-24-16 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.

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!

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. Just make sure you number going down and not across, and 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…..

Chemistry 8-18-16 Lab Safety Test

CHEMISTRY: Great job with 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

  • All the lab apparatus at your lab station and in the slide show – be able to identify it all and know what all the apparatus is used for.
  • Know the parts of the Bunsen burner and how to light one.
  • Know the parts of the balance and be able to measure mass with a balance AND volume with a graduated cylinder.
  • I’ll ask you about safety control equipment and where it’s found in the lab.
  • I’ll also have the safety symbols and the information they represent on the test
  • Make sure you can both set up or draw and label diagrams for filtering, boiling, evaporating, and heating intensely.

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 A-1 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!!

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!

So why can some humans float – or not? Looking forward to seeing what you do with the lab tomorrow! :)

Web Post Comments Ideas

Happy Thursday! Are you having a difficult time 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 for ideas for good comments that will receive credit.

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.

Still don’t know what to do?

  1. Click on the title of any web post from the week that I have made for your class.
  2. Scroll to the very bottom of it where it says “Leave a Reply” – you may have to scroll past comments from other people, but you can reply to those also!
  3. Enter your name correctly and your email.
  4. Type in your comment (see the info above.)
  5. Type in the Anti Spam characters in the space provided.
  6. Click Post Comment and you are done!

Hope you have a great weekend!!

Physics 8-17-16 Measurements in Physics, Pt. 1

PHYSICS – Hey guys, here’s part 1 of the overview we did on the SI system. No sound on the vodcast from today, so I’m including the lecture from last year. :)

You remembered a lot! Were you surprised at yourself? The hardest part, I think, will be getting back in the habit of showing all your work, using conversion factors, units, dimensional analysis, sig figs, etc. We’ll finish reviewing sig figs on tomorrow. Happy, happy!

Chemistry 8-17-16 Filtering

CHEMISTRY: So how do you separate salt and sand? Did you conquer filtering? Make double sure of two things before tomorrow: 1) read the lab before you come to class to do it, and 2) get a head start on the questions at the end of the experiment packet.

Your test is coming up VERY SOON! Have you started studying? In addition to the lab safety packets and the lab safety video, here is some VERY IMPORTANT information to study

  • All the lab apparatus – be able to identify it all and know what all the apparatus is used for.
  • Know the parts of the Bunsen burner and how to light one.
  • Know the parts of the balance and be able to measure mass with a balance AND volume with a graduated cylinder.
  • I’ll ask you about safety control equipment and where it’s found in the lab.

Also, don’t forget that the entire Exp A-1 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 FRIDAY.

God bless you as you study! It’s a ton of information, but you can do it!! I’ll be praying for you!!
