Chemistry 8-22-19 SI Measurements

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 Thursday, August 29.

Chemistry 8-19-19 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. Be sure and turn it in at the beginning of class tomorrow.

Speaking of that, tomorrow you’ll be using what you know about the scientific method to analyze a myth that was tested on Mythbusters.

On Wednesday, 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 Wednesday!

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

Chemistry 8-15-19 Lab Safety Test

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!

Here’s the review that we went over in class. 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 and evaporating

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 8-13-19 Measuring Mass & Volume

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.

If you 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 8-13-19 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. Be sure and 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!!!

Chemistry 8-12-19 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.

Make sure and check your syllabus to be ready for tomorrow! Here are some important reminders:

  • Be sure you have entered your information in the first day of class form – it’s in the the post I wrote called, “Beginnings” – it’s due TODAY!!
  • Don’t forget the QUIZ tomorrow – Lab Equipment from the slide show on Lab Equipment post. Just the equipment, not the use.
  • Be sure and read and highlight Pt. 1, The Bunsen Burner, for tomorrow. If you didn’t get a copy in class, you can find it and print it from the Lab tab here on the website.

Chemistry 8-9-19 Lab Equipment

CHEMISTRY – Hey guys! There’s lots of useful equipment for chemistry this year! Below is a slide show with an overview of the apparatus that you’ll use in the chemistry lab. Click on the black arrow to start the slideshow. For all of the equipment:

  • Know the name of each item.
  • Explain the use of each item (it’s written in white on the slide)

The second slide show is a great tour of our lab. It’s very important information about where stuff is and what it’s used for. I think you’ll find it very helpful. Both of these would be a great way to study equipment for the test! (Hint, hint!) 🙂

HOMEWORK: First though, lets talk about homework.(Don’t forget to also check your syllabus!!)

1) Lab Equipment – Study the lab equipment in the slide show below and then practice identifying the equipment in the Lab Apparatus Review on Power School. It’s due on Monday by class time. If I counted right, there are 33 of them. By the way, pictures of most of these are also in the back of the Safety Packet.

2) Lab Safety ContractSince we’ll be in lab so much, it’s important that you write your own lab safety contract. Here’s how you do it::

  • From the first couple of pages of the Safety Packet that you got in class (or it’s also here under the Lab tab), write the lab safety statements as your contract.
  • They may be handwritten on notebook paper or typed (must be printed). You only have to write the first part of the rule that is bold. There are 29 in all and they almost all start with “I will…”.
  • At the end of your contract – after the last statement, hand write “I agree to abide by these rules.” Then sign underneath and date it. Even if you type the safety rules, you’ll need to hand write this last part.
  • Due Monday!

Beginnings

What a great first day! You’re off to a great start on a truly tremendous adventure. I’m so glad you’re in my class and that I’ll be able to share this adventure with you! Here is your assignment for tomorrow and for the next few days.

  • TODAY – Sign up for Remind. Follow the instructions on the Technology Overview sheet you got in class today. This sheet is also here on the website under the “Worksheets/Handouts” tab. (Your parents can sign up for this also.)
  • Read the class info sheet front & back – sign it and ask your parents to sign it (front & back!!!). The Class info sheet is due by MONDAY in class. The Class Info sheet is also here on the website under the “Class Procedures” tab on the top left of this page, if you didn’t get one in class.
  • Enter your information in the form below. You may need to use the scroll bar on the right side of the form to get to the bottom of it. The form must be completed by 8:00 A.M., THIS Monday morning, but I encourage you to do it before then!
  • Check your syllabus daily to see what we are going to be doing in class this week, for homework, and for the due dates for class supplies!!

ExploreZone 2019


So I’m going back through photos this summer and I’m once again blown away by the phenomenal experience that our NCS high school science students provided for their elementary friends at ExploreZone 2019! It was an incredible day of science adventure and fun – for all!

NCS elementary students explored an awesome glow wall, shooting flames, liquid sand, virtual reality, Bernoulli’s Principle, gooey worms, exploding art, and many, many other exciting physical science and life science exhibits – and our big kids made it possible. I am forever thankful!!

Click to see hundreds more photos and videos from ExploreZone 2019. Yeah – we took a lot of pictures!
