Physics 9-26-16 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.

Hon Chemistry 9-23-16 Chemical Changes & Conservation of Mass

HON CHEMISTRY: More review today on states of matter and 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?

God bless you as you memorize the symbols of the elements (complete list on your syllabus), as well as the atomic numbers and mass numbers for elements 1 – 30. Actively work to memorize them!!

Physics 9-23-16 Component Method of Vector Addition

PHYSICS – Great job today!! You are on your way to conquering the component method of vector addition. So which do you like better? Give yourself a chance to get used to separating everything into x and y and it will click, I promise!

Hon Chemistry 9-22-16 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! :)

Physics 9-21-16 Intro to Vectors & Relative Motion

PHYSICS: Awesome introduction to relative motion and vectors! Wow!

Here’s the a vodcast from a couple of years ago on the intro to vectors – and below that, a MOST AWESOME demonstration of the addition of two vectors with (almost) equal magnitude and opposite direction. Did you guess what the ball would do?

Chemistry 9-21-16 Graphing Exercise Recap

CHEMISTRY: How’d you do today with your Excel graph? Once you get the hang of it, I predict you are going to want to always do these kind of graphs instead of hand drawn!

HOMEWORK INFO: You must bring a printed rough draft of BOTH of your graphs to class tomorrow – Thursday. Be sure and email your Excel graph to yourself – or save it some other way so that you can access it from school in case you need to make changes!

HOMEWORK UPDATE: Double check the Exercise 1 that you did. If you did the physics Exercise 1 (graphs had questions about motion) then you can redo it if you want to – you don’t have to redo it, but it will be graded for accuracy. Here’s the link the the CORRECT Graphing Exercise 1

Speaking of which – be careful with your hand drawn graphs! 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.

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 a JPEG.

Chemistry 9-20-16 Making Excel Graphs & Graphing Exercise 1 – 2

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

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

IMPORTANT: 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 three graphing handouts:
  2. Watch the vodcast below for further instructions on the assignment AND for a tutorial on how to make graphs in Excel.
    • 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!!

Chemistry 9-19-16 Fundamental Science Skills Graphing Activity

Quick – list 20 things you remember from the 8th grade about interpreting and reading graphs! Not to worry – today you’re going to begin reviewing those important concepts and techniques. Here is your assignment for Monday:

IMPORTANT: Today’s assignment is one that you will have to complete at school. The program is on the school laptops in our room and on the computers in the computer lab.

  1. Find the “Fundamental Science Skills” program on your computer.
  2. In the Graphing Skills section, click on “Graphing Data Points.” Read through and practice in each section VERY CAREFULLY!
  3. After you have completed each review section, go to the exam and complete it.
    • You must enter your name in the exact format you do when you title a lab – including the title of the activity.
    • IMPORTANT: Your answers and the format of it all must match exactly with the correct answer to receive credit. (Sometimes being exactly correct is extremely important!)
    • Click on “Check Your Answers.” When you have 100% accuracy, bring your lap top to me to check your Check Answers Results Sheet. If you are doing the assignment outside of our class period, print off your exam results sheet and bring it to me to check.
  4. The Graphing Data Points assignment is due Tuesday, by 3:30 P.M.
  5. Next, if you have time, go to the Worksheet Tab and read Graphing Exercises 1 & 2. We’ll start that tomorrow!

Holler if you have any questions!
