Physics 9-26-18 Relative Motion Revisited – Motion Down a River and Kid on a Slide with a Water Gun

Posted on by

PHYSICS – Wow, we finally made it to the official end of chapter 3! Do you realize how much you’ve accomplished? Awesome!

How’d you do with relative motion “revisited”? You know, you’ve done this already. The only new part is the motion of objects in the same direction and opposite directions, relative to each other. Don’t forget, you’ll use what you learned about vector addition to work those “boat goes across a river” and “plane experiences a head wind” types of problems.

Here’s another look at relative motion – and a heads up on the kid on a slide with a water gun problem.

Need extra help? Help session tomorrow morning, Thursday, 7:20ish. UPDATE – test rescheduled for Monday!

Chemistry 9-26-18 Making Excel & Google Sheets Graphs AND Graphing Exercise 1 – 2

Posted on by

CHEMISTRY: Today you are going to learn (or review) how to make graphs on Excel (or other data analysis software) by watching the video below at your own pace.

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

IMPORTANT: Don’t let the assignment confuse you! What it basically means is that you will make two graphs – one hand drawn and one Excel. And then, you will answer some questions about the graphs and turn in the whole assignment as a PDF – it must be submitted by this coming Tuesday, October 2, 8:00 A.M.

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 or Google Sheets, you may need to modify the instructions to fit your device.

  1. Under the worksheet tab, open these three graphing handouts – note, there is no handout for Google Sheets:
  2. Watch one of the vodcasts below for a tutorial on how to make graphs in Excel or Google Sheets.
    • 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 1 assignment, pay very close attention to the instructions. 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 to make sure you have all the parts of the graph covered.
  4. Google Sheets only: If you ever need to add subscript or superscripts to the axis labels in Google sheets, try copying and pasting whatever number you need from this set in to the axis title in Google sheets: ⁰¹²³⁴⁵⁶⁷⁸⁹₀₁₂₃₄₅₆₇₈₉
  5. Now go forth and conquer graphs!!
