Physics 8-17-17 More Mathematics & Analyzing in Physics

PHYSICS: Hey – did all the info on significant figures and types of proportions and graphs come back to you? Quick word about the order of magnitude problems – some may be easy, a few more challenging. Give them your best shot!

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!

So why can some humans float – or not? Looking forward to hearing your proposal and seeing what you do with the lab tomorrow! 🙂

Chemistry 8-17-17 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!!

Web Post Comments Ideas

Happy Wednesday! 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!

Chemistry 8-16-17 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.
  • I’ll also have the safety symbols and the information they represent on 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 FRIDAY.

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

Chemistry 8-15-17 Measuring Mass & Volume

CHEMISTRY: Did you remember about massing with a balance and measuring volume with a graduated cylinder?

Here are the few notes from today – some specifics on how to read the instruments and how far out you carry your measurements, etc.

Chemistry 8-14-17 Lighting a Bunsen Burner

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!!!

Physics 8-11-17 Measurements in Physics, Pt. 1

PHYSICS – Great job with your whirly gigs! Congrats, Ethan!! BTW – thanks to all of you for being so flexible with our tech issues!

Here’s part 1 of the overview we did on the SI system. 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 when you get back from the senior retreat. Happy, happy!

Chemistry 8-11-17 Lab Safety & Procedures

CHEMISTRY: Wow! Great video, but do you feel like you have information overload!?

Here is the lab safety video we watched in class. It does have a ton of info, and the thing is, you absolutely must know it – and not just for the test, but also throughout the year in lab. It’s a really good idea to watch it again and take notes as you go.

Be sure and check your syllabus to be ready for Monday! Here are some important reminders and an important UPDATE:

  • Be sure you have entered your information in the first day of class form – it’s in the the post I wrote called, “Beginnings” – due this morning (Friday), by 8:00 A.M.
  • The lab safety rules that you are to write tonight for homework are on the first couple of pages of the Safety Packet. They must be handwritten on notebook paper. You only have to write the first part of the rule that is bold. At the end of all the rules, write “I agree to abide by these rules.” Then sign underneath and date it – due Monday in class.
  • I have printed the lab for Monday.Be sure and read Pt. 1, The Bunsen Burner, for Monday!
