Chemistry 10-3-17 Intro to Chemistry

CHEMISTRY: We’re finally starting what chemistry is all about! Here’s the lesson from Tuesday. Can you apply the branches of chemistry and types of scientific work? As you go through the chapter, make sure you have the vocab down, and be sure you’re able to apply what you learned each day!

Now….how would you describe this copper ore? Let’s talk about that tomorrow!

Physics 10-2-17 Angular Projectile Motion

PHYSICS – So we are finally putting it all together – angular projectile motion! Here’s the lesson – some homework discussion and then angular projectile motion.

The number one thing to remember – Never use the resultant velocity to do more than find the vertical and horizontal components! And vertical is vertical, horizontal is horizontal and don’t ever mix the two!

Physics 9-28-17 Horizontal Projectile Motion

PHYSICS: Great job today – and applying stuff from the last chapter no less!

Just go slow and easy, talk yourself through what you are doing and ask if the formulas you are using are legit. You’ll master it in no time flat. Watch out for squirrels throwing nuts!

Chemistry 9-28-17 Making Excel Graphs

CHEMISTRY: Today you are going to learn how to make graphs on Excel by watching the video below at your own pace.

Here are the instructions for Thursday. (You are going to be dreaming about graphs before it’s all over!)

IMPORTANT: The video you will watch has the assignments backwards – Ex 1 is now Ex 2, and Ex 2 is now Ex 1. What this basically means is that you will make the graphs first – the printed rough draft of the Excel graph is due Monday in class. You’ve already finished the hand graph and the questions! The entire assignment – all three pages of it, are due by Tuesday, Oct. 4, by 8:00 A.M – submitted  as PDF 2X (this means to Google Drive &

You can do this assignment at school or at home with your own computer. If you use any device other than a PC or any graphing tool other than Excel, you may need to modify the instructions to fit your device.

  1. Under the worksheet tab, open these two graphing handouts:
  2. Watch the vodcast below for further instructions on the assignment AND for a tutorial on how to make graphs in Excel. Start the vodcast at 6:00 minutes.
    • When you get to the part of the video where I tell you that you can stop watching the tutorial, if you want to stop and work on your own, be sure and FIRST scroll to the end of the vodcast (at about minute 28:40) for hints on competing Exercise 2.
    • My advice is to use a split screen view on the laptop with the video on one side and Excel open on the other side of your laptop screen. Watch the video and at the same time pause it as you follow along with the steps in Excel. Holler if you need me to show you how to do a split screen view. Or Google it! 🙂
  3. When you begin working on the Graphing Exercise 2 assignment, pay very close attention to the instructions. (Watching the video will help.) Also, pay close attention to the sheet on How to Construct a Line Graph, and How to Make a Best Fit (Scatter Plot) Line Graph in Excel 2010 – UPDATED.
  4. Now go forth and conquer graphs!!

Hon Chemistry 9-27-17 Chemical Changes & Conservation of Mass

HON CHEMISTRY: More review today on chemical properties and chemical changes. Can you determine if a chemical change has occurred? And what about energy? How is that important in chemical changes?

How’s the Graphing Exercise 1 coming along? Are you setting good deadlines for yourself? Would you like me to take a look at your graphs?? Holler if you need some advice!

Physics 9-27-17 Review of Component Vector Addition

PHYSICS: So what do you this is the resultant of these “vectors”?!?

Great job with the component method of vector addition! My main take away from today – make sure you show all your work in a very orderly fashion! Here’s the review from today.

Chemistry 9-26-17 A Look at Hand Drawn Graphs

CHEMISTRY: Were you happy with your hand drawn graph? Here’s the very short review today of good and some not so good graphs.

HOMEWORK INFO: For tonight (Tuesday), make your final copy of your hand drawn graph. Also, answer questions A – I in a Word or Google doc. (You were going to have time in class tomorrow, BUT we’re going to probably spend most of the time working on the test.)

Speaking of the first graph – be careful with your hand drawn graph! Watch this vodcast for good and bad examples. Carefully review the instructions on how to draw them. Common mistakes – switching independent and dependent variables, line not a best fit curve, graph too small, forgetting to label the axis, the scale on an axis not consistent.

Super important – when you scan your hand drawn graph to insert it into your Word or Google doc, remember that you have to scan it as an JPEG image and NOT a PDF this time! If you are using an app to scan, you’ll probably need to change the settings to scan as an image.

And finally – NEATNESS is very important all the way through this assignment!!

Hon Chemistry 9-26-17 Intro to Chemistry

HON CHEMISTRY: So now that you know how to use all the tools we’ll need in chemistry, it’s time to start talking about ….chemistry!!

Were you able to able to make applications with the branches of chemistry and categories of scientific work? We’ll finish talking about the properties of matter tomorrow. Don’t forget the applications!

Now it gets interesting! 🙂
