Chemistry 10-18-17 Conservation of Energy

CHEMISTRY – Happy Day!! We finished the chapter! Now it’s time to go apply what you’ve learned. Have you begun to think about ways you could separate that mixture? And what about a Plan B? πŸ˜‰

So can energy be destroyed? Good job on tracing the energy transformations from one form to another. Applications, applications! Make sure you can apply what you learned today – on the test (and in life!). Did I mention that already?

Hey, have you had a chance to check out the chapter 1 study suggestion sheet? Let me know if there is anything you need help with before the test! (And you’re still learning the symbols of the elements, right?!?) πŸ™‚

Chemistry 10-17-17 Elements & Intro to the Periodic Table

CHEMISTRY – Happy Tuesday! Here’s our overview of the elements and intro to the periodic table. Did you feel like it was mostly review?

How is the element handbook search going? You will be responsible for the information from Handbook Search 1 on the test. Tell enough to show what distinguishes that element as the type that it is – physical and chemical properties, where it can be found, what it’s used for, anything particularly unusual about the element, but don’t go into minute detail – just the main facts. You for sure don’t have to copy information from all the tables in the book.

Here is the link for the video clips on copper, phosphorus, and silicon that you will need to watch for the Element Handbook Search and for the TEST!! www.periodicvideos.com. The information on these video clips will be on the test.

Speaking of the test, have you had a chance to check out the Chapter 1 Stuff to Know sheet? Let me know if there is anything you need help with before the test! (And you’re still learning the symbols of the elements, right?!?)

Chemistry 10-16-17 Classification of Matter

CHEMISTRY: Here’s a mixture that looks like it might be worth investigating – bacon caramel popcorn! I mean, I like bacon and I like caramel popcorn, but bacon caramel popcorn? Hmmmm….

So now that you know about mixtures, could you figure out how to separate one? Keep these notes handy!

Chemistry 10-4-17 Properties & Changes

CHEMISTRY: So how do you know if something is a physical or a chemical change? Applications, applications! Make sure you can apply what you learned today. Ditto on the law of conservation of mass.

Don’t forget that we will do the thLab: Candle Observation in class tomorrow!

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 Β as PDF 2X (this means to Google Drive & Turnitin.com).

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! πŸ™‚
  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 9-26-17 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!!

Chemistry 9-25-17 Making Excel Graphs & Graphing Exercise 1 – 2

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

For Monday and the hand drawn graph, you’ll need to channel all that you learned in the 8th grade about drawing graphs. Might be a good idea to review this handout below, I’m just saying. The rough draft of the hand drawn graph is due tomorrow.

Next, here are the instructions for WEDNESDAY. (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.
