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? Let’s play with a chemical change tomorrow!

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! 🙂

HON 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 Thursday – the last graph for Exercise 1. (Are you dreaming about graphs yet?!?)

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 Monday, September 23, 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. 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! 🙂
2. 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.
   • If you need a sample set of data to play around with, click here: Sample Data for Graphing Practice
3. 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
4. Now go forth and conquer graphs!!

HON CHEMISTRY: Today you began reviewing how to make your own hand drawn graphs using Graphing Exercise 1. Did you remember what you learned from a long time ago? Any questions about Graphing Exercises 1 & 2? (You are going to be dreaming about graphs before it’s all over!)

Under the worksheet tab, open these three graphing handouts. Use these handouts to make sure you are doing the hand drawn graph correctly!

• • How To Construct a Line Graph On Paper
  • Graphing Exercises 1 & 2

Need a refresher? Watch this vodcast for good and bad examples. Carefully review the instructions on how to draw them. Common mistakes – switching independent and dependent variables, the scale on an axis not consistent along the axis, graph too small, line not a best fit, forgetting to label the axis, etc.

And finally – NEATNESS is very important!! Rough draft of all your graphs are due Friday – but I’ll be glad to check them early!

Welcome to Graphing 101 – or what I like to call, “A Quick Review of Everything You Learned About Graphing in the 8th Grade.” 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 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.
   • 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.
   • IMPORTANT: Your answers and the format of it all must match exactly to receive credit. (Sometimes being exactly correct is extremely important!)
4. The Graphing Data Points assignment is due by the end of the class period.
5. Next, go to the Ring Challenge and complete it. You will need headphones or earbuds. If you don’t finish in class, bring the completed sheet to me to check off. It is due by the end of the school day on Friday.

Holler if you have any questions!

HONORS CHEMISTRY – Happy use your brain day!! Can you now use what you’ve learned about density? Who is going to be your spokesperson? When is your lab going to be due? Do you need two due dates???

Can’t wait to “watch” you work!

HON CHEMISTRY: Great job using conversion factors to work more advanced conversions! It’s good to able to convert from one unit to another, but can you use that info to solve a real world problem?

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!). Now go forth and conquer!

HON CHEMISTRY – You’ve learned to gather the “pieces of the puzzle”, now it’s time to put them together so they can have meaning! Here’s our look again at density, and then our overivew of direct and inverse proportions. Just brief info for the test for now, and we’ll put it to practice in a couple of activities after the test.

How’re you doing on these last problems? Are you able to pull together all we’ve done in this chapter? When working problems, don’t forget to follow these problem solving steps:

• 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?

As you study, remember, don’t just read your notes – practice your notes, practice the problems, practice the memorization!! By the way have you had a chance to check out the Chapter 2 Stuff to Know sheet and the chapter 2 study suggestions sheet? They are under the Test Info tab.

HON CHEMISTRY: Can estimate out how fast you can drive in at least one parking lot in Guatemala – and can you show me how you solved the problem? Even better, can I trust the validity of your work?

Good job on remembering how to use conversion factors! 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!)
