Chemistry 10-17-18 Energy (And Updated Syllabus)

CHEMISTRY – Happy Day!! You just took the last notes from the chapter, now it’s time to go apply what you know!!

UPDATED SYLLABUS – Have you printed and checked it? Super important for new info.

Great review today! 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 10-2-18 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. Make sure you have a printed copy!

Chemistry 10-1-18 Intro to Chemistry

CHEMISTRY: We’re finally starting what chemistry is all about! Here’s the lesson from Monday. Can you apply the branches of chemistry and types of scientific work? As you go through the chapter, make sure you have the vocab down, and be sure you’re able to apply what you learned each day!

Now….how would you describe this copper ore? Let’s talk about that tomorrow!

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

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! πŸ™‚
  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: β°ΒΉΒ²Β³β΄β΅βΆβ·βΈβΉβ‚€β‚β‚‚β‚ƒβ‚„β‚…β‚†β‚‡β‚ˆβ‚‰
  5. Now go forth and conquer graphs!!

Chemistry 9-25-18 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 – you’ll bring your physical copy of the graph tomorrow.

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, 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!!

Chemistry 9-12-18 Chapter 2 Test Practice & Help Session

CHEMISTRY – Wow! Is your mind blown when you think about all that you’ve learned to do in chapter 2?

Here’s practice on some of the problems from this chapter. Here’s the vodcast from the “day before the test practice”,and I also posted below that a help session that will have some extra practice, BUT the batteries died about 13 minutes in, so no audio after that, but you can watch how we worked problems.

Remember, don’t just read your notes – practice your notes, practice the problems, practice the memorization!! If you haven’t done so already, make sure to check out the Chapter 2 Stuff to Know sheets under the Test Info tab. Great info!!! And continue to practice with these online games and quizzes:

Online Textbook: There are wonderful Interactive Review Games with your online text. First open chapter 2. Then click on the the Student Premium tab, then Interactive Review Games.

sciencegeek.net has great interactive quizzes with questions like I’ll ask on the test. Find the unit that corresponds to the topics we’ve been studying and begin to quiz yourself. There are answers, too!

God bless you as you study! I’m praying for you!!

Chemistry 9-10-18 Relationships Among Data

CHEMISTRY – Can you believe it? We’ve finished the chapter! Here’s the lecture from today on direct and inverse proportions AND a look at one of the conversion factor problems from last night’s worksheet.

Speaking of tests, have you gone to the TEST Info tab yet? You might find something that will help a lot as you study!!!

Also, don’t forget to check out the Interactive Review Games with your online text and also the review at sciencegeek.net. Great practice with both memorization, concepts and problem solving!

God bless you as you study this week! I’m be praying for you!!

Chemistry 9-5-18 Homework Conversion Factor & Density Problems

CHEMISTRY: Here is our discussion from today of some of the conversion factor problems from the homework. Are you getting an answer, or are you showing proper work that shows that you understand the process? Are you practicing them the correct way? You want to get great at working these yourself, not just get great at watching me work them!

What about the test coming up – have you started preparing? Be sure and check out the Test Info tab here on the website!

Chemistry (and Honors) 9-4-18 Using Density

CHEMISTRY – Hey guys, here’s a pic of some “high density” koi that I saw in Hawaii (at the Dole Pineapple Plantation, of all places!). Great review on density problems today, and more! Remember, in chemistry we use math as a tool, therefore we might work problems a little differently in chemistry than you do in your math class.

When working these problems, don’t forget to follow the problem solving steps we discussed today:

  • 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?

Need more practice? Help session TOMORROW morning, 7:30ish A.M.

Chemistry 8-30-18 Conversion Factors

CHEMISTRY: Great job with our start on using conversion factors to work problems! Hopefully this was a review from your earlier academic life. We’ll crank it up a notch tomorrow!! πŸ˜‰

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, what about a HELP SESSION?
