PHYSICS – Great job today!! You are on your way to conquering the component method of vector addition. So which do you like better? Give yourself a chance to get used to separating everything into x and y and it will click, I promise!

CHEMISTRY: We’re finally starting what chemistry is all about! Here’s the lecture from Wednesday on the intro to chemistry. 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!
BTW – How are you doing on learning the symbols of the elements? Is that something you’ve had to do in your other classes? Don’t forget to check out quizlet.com – you might find an old one, or you can make one for yourself. It’s a great way to work on memorizing them! 🙂

HON CHEMISTRY: Short classes – you’ve gotta love them!! Here’s the last of the discussion on chemical changes, and….
…so did you see the Law of Conservation of Mass today? Why not? What are you going to do differently in the lab tomorrow, and why do you think it will work? Hmmmm….

HON CHEMISTRY: More review today on states of matter and chemical properties and chemical changes. Can you determine if a chemical change has occurred?

PHYSICS: Awesome introduction to relative motion and vectors! Wow!
Here’s the short vodcast from class today – and below that, the best demonstration of relative motion EVER!! 🙂

PHYSICS – Hey guys, great job today on graphical vector addition, resultants, and the like. How’d you like drawing motion?
We’ll spend tomorrow practicing, so don’t forget your protractor and graph paper!

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 on tomorrow. Don’t forget the applications!
God bless you as you memorize the symbols of the elements (complete list on your syllabus), as well as the atomic numbers and mass numbers for elements 1 – 30. Actively work to memorize them!!
Now it gets interesting!
🙂

CHEMISTRY: How’d you do today with your Excel graph? Once you get the hang of it, I predict you are going to want to always do these kind of graphs instead of hand drawn!
HOMEWORK UPDATE: You must bring a rough draft of BOTH of your graphs to class on Monday. Be sure and email your Excel graph to yourself – or save it some other way so that you can access it from school in case you need to make changes!
Speaking of which – be careful with your hand drawn graphs! 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.
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 a JPEG.
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 Thursday. (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.

PHYSICS: So this is going to be the oddest post. Here is the vodcast today with NO AUDIO for the first – well, more than half! But you wanted it, so here it is! 🙂
