Hon Chemistry 10-13-17 Elements & Intro to the Periodic Table

HON CHEMISTRY – Wow! Do you realize what we just did?!? We finished the chapter!!! Here’s the last lecture from chapter 1 – an overview of the elements and intro to the periodic table. Did you feel like it was mostly review?

Now for the element handbook search! You will be responsible for that information – both search 1 & 2, on the test. On the first part, tell enough to show what distinguishes that element as the type that it is, and also anything particularly unusual about the element, but don’t go into minute detail – just the main facts.

Another great resource for the Element Handbook Search (and for the TEST!!) are these video clips on copper, phosphorus, and silicon that a group of chemistry researchers have put together at www.periodicvideos.com. Watch these as you do the element handbook search. The information on these video clips will be on the test.

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?!?)

Hon Chemistry 10-4-17 Classification of Matter

HON CHEMISTRY: Happy Wednesday! Great job today on asking questions to classify matter! How are you doing on the examples of homogeneous and heterogeneous matter? Here’s a question to think about again, can you tell me three different types of homogeneous matter?

And no, this isn’t part of a moonshine still, but it is copper and I thought it looked kind of cool! Speaking of….why do you think they use copper coil in stills??

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!

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! πŸ™‚

Hon Chemistry 9-20-17 Making Excel Graphs AND Graphing Exercise 1 – 2

HON 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 Wednesday. (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 two graphs first – printed rough drafts of both are due Friday in class. And then, you will do the online graphing worksheet last – it must be submitted by this coming Monday, 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, 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! 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!!

Hon Chemistry 9-19-17 Fundamental Science Skills Graphing Activity

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 Tuesday.

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. Check the syllabus for the due date!

Holler if you have any questions!

Hon Chemistry 9-11-17 Relationships Between Data & Test Info

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! The recording today had no audio, BUT here’s an overivew of direct and inverse proportions from last year. Just brief info for the test for now, and we’ll put it to practice in a couple of activities after the test.

By the way, speaking of tests and putting thing together, how’re you doing on these last problems? Are you able to pull together all we’ve done in this chapter?

I found an old recording of a help session from last year and I posted that below as well. Conversation factor problems and maybe a density one or two? CAUTION: The first ten minutes or so are a bit scratchy – I think the mic kept getting caught on my shirt!

As you study, remember, don’t just read your notes – practice your notes, practice the problems, practice the memorization!! Be sure and check out the Chapter 2 Stuff to Know sheet and the chapter 2 study suggestions sheet. They are under the Test Info tab. God bless you! I’ll be praying for you!!

Hon Chemistry 9-8-17 Chapter 2 Test Info

HON CHEMISTRY: I miss you today! Are you spending time on this long weekend studying for your test? Have you begun to organize everything you need to study? Do you have a plan?

By the way, speaking of tests, how’re you doing on these last problems? Are you able to pull together all we’ve done in this chapter?

As you study, remember, don’t just read your notes – practice your notes, practice the problems, practice the memorization!! Here are a couple of resources that might help you as you prepare!

Chapter 2 Formulas & Stuff to Know

Chapter 2 Study Suggestions

Reg & Hon Chemistry 9-6-17 Homework & Conversion Factor Problems, Etc.

REG & HON CHEMISTRY: Short class, but great job with our start on using conversion factors to work advanced problems! 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 9-5-17 Conversion Factors

HON CHEMISTRY: So now you can figure out how fast you can drive in at least one parking lot in Guatemala! 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!)

Make sure you practice using your notes tonight, it’ll help you remember the steps we followed today in class!

If you need more practice on these or other problems – HELP SESSION tomorrow, Wednesday, morning, 7:20ish A.M.
