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™‚

Hon Chemistry 10-10 & 11-18 Elements & Intro to the Periodic Table

HON CHEMISTRY – Wow! Do you realize what we just did?!? We finished the chapter!!! Did you feel like today was mostly review?

Now to finish 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?!?)

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!

Physics 9-27-18 Chapter 3 Test Overview & Problems Practice

PHYSICS – Great review today with conceptual info from this chapter! And that led to some great work on the monkey-hunter problem and stone thrown from the top of the building problem! One last help session – Monday morning, 7:20ish A.M.

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

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

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!!

Hon Chemistry 9-25-18 Physical & Chemical Changes and 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? Let’s play with a chemical change tomorrow!
