Science In the News Assignment for Tuesday

Here is the Science In the News assignment for Tuesday:

How can chemistry, physics – or any other type of science, technology, engineering, and mathematics (STEM) be important to your everyday life? TONS of ways, and this year we’ll be using Science In the News to research just that!

IMPORTANT guidelines for the assignment:

  • For today, you will have two articles to choose from. After today, you will find your article on websites like or
  • Make sure you pick an article you find interesting and that you understand!!
  • Make sure you pick an article that you can use to answer the questions on the Science In the News sheet. If there are questions you cannot answer with the type of article you have – pick another article!!!
  • The SItN assignment must be handwritten on notebook paper – you may write on the back

IMPORTANT #2: When you are finished today, put your laptop up in the correct slot and plug it in!!

Chemistry 9-6-19 Relationships Among Data & Homework Problems Review

CHEMISTRY – Can you believe it? We’ve finished the chapter! Here’s the lecture from today on direct and inverse proportions AND a look at the density and conversion factor problems from last night’s worksheet.

Homework UPDATE: The thLAB: Building a Balance due date is moved to Tuesday. The Chapter 2 Review Worksheet is due Monday. Be sure and read the instructions carefully for both!

Speaking of tests, have you gone to the TEST Info tab yet? You might find something that will help a lot as you study!!!

Also, don’t forget to check out the Interactive Review Games with your online text and also the review at Great practice with both memorization, concepts and problem solving!

God bless you as you study this week! I’m be praying for you!!

Chemistry 9-4-19 Cobra Venom and Liters of Water

CHEMISTRY: How are you doing with some of the longer conversion factor problems? Remember, you’re not just trying to get an answer. Most importantly, you are learning to express a logical progression of thought – from one unit to another. I think I see you getting way better at it! Keep practicing until you can do it by yourself with no help!!

Here are the ones we did in 3rd period today – #14, cobra venom, and #16, liters of water.

Chemistry 9-3-19 Using Density & Conversion Factors

CHEMISTRY – Hey guys, here’s a pic of some “high density” koi that I saw in Hawaii (at the Dole Pineapple Plantation, of all places!). Great review on density problems today, and more! Remember, in chemistry we use math as a tool, therefore we might work problems a little differently in chemistry than you do in your math class.

When working these problems, don’t forget to follow the problem solving steps we discussed today:

  • Analyze – write down what you’re given and what you’re looking for
  • Plan – write a formula where you isolate the unknown on one side by itself
  • Compute – plug in your data, numbers and units; then cancel the units, and if they cancel correctly, go on to the calculator. Be sure and give your answer what the correct units.
  • Evaluate – does your answer make sense, have you used the correct units, do you have the correct sig figs?

Chemistry 8-30-19 Conversion Factors Homework

CHEMISTRY: Lots of great practice today using conversion factors! How did you do on your homework? Do you need to do it again?

HOMEWORK UPDATE for Friday:Don’t do the homework on the syllabus for Friday. Instead redo Thursday’s homework showing correct work if you haven’t already or if you missed them the first time. Super important that you know how to do these for the rest of the year!!

Chemistry 8-29-19 Conversion Factors

CHEMISTRY: Great job with our start on using conversion factors to work problems! Hopefully this was a review from your earlier academic life. We’ll crank it up a notch tomorrow!! πŸ˜‰

Remember, this isn’t just about getting an answer – some of you can do that in your head. This is about being able to convert from one unit to another using the Q-formula. (And yes, you have to do it that way!)

Make sure you practice using your notes tonight, it’ll help you remember the steps we followed today in class!

If you need more practice on these or other problems, what about the HELP SESSION tomorrow morning? 7:00ish A.M. πŸ™‚

Chemistry 8-28-19 Significant Figures, Pt. 2 & Scientific Notation

CHEMISTRY – I like the way you are catching on to significant figures! Here are the notes on calculating with Sig Figs – knowing how far to carry out your answer.

Remember, the best way to really learn all of the things from this chapter is practice, practice, practice! That’s the reason it’s so important to do your homework! I give it to you so you can practice and put together all we talked about in class ….cuz I love you! πŸ™‚

Also super important – SI quiz tomorrow! Make sure you are actively studying for it, not just looking over it!!

Chemistry 8-27-19 Accuracy & Significant Figures

CHEMISTRY – Here’s our look at expressing accuracy with percent error and uncertainty. Keep that formula handy! We also began looking at significant figures today. Did you remember them? Use them and you will!

Two super important things: Make sure you are actively studying for the SI quiz! Also 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! πŸ™‚

Be sure and check your syllabus!!

Chemistry 8-23-19 Fine Tuning Measurements

CHEMISTRY: Happy Friday! Here’s the last of the info on properly writing 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!!
