PHYSICS – So we are finally putting it all together – angular projectile motion! Here’s the lesson from today – well, a lot of homework discussion and then angular projectile motion.
The number one thing to remember – Never use the resultant velocity to do more than find the vertical and horizontal components! And vertical is vertical, horizontal is horizontal and don’t ever mix the two!

PHYSICS – Great job today, and applying stuff from the last chapter no less! Too bad I forgot to turn on the mic(!), BUT here’s the lecture from last year that will get the job done if you need a review. This one actually has an extra problem to practice!
Just go slow and easy – talk yourself through what you are doing and ask if the formulas you are using are legit. You’ll master it in no time flat. Watch out for squirrels throwing nuts!

HON CHEMISTRY: Happy Monday! 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??

PHYSICS: I do believe you are well on your way to conquering the component method of vector addition. Good job! Pay careful attention to the smallest details – it can make a huge difference.
Here’s the overview of the conceptual questions from the homework – super short!

HON CHEMISTRY: Happy Friday! Great job tracing energy changes through physical and chemical changes.
So…. the law of conservation of energy, endothermic/exothermic, and potential and kinetic energy . . . How much of it can you find in bungee jumping?
And who knew there were so many questions you could ask about matter?
🙂

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.
Speaking of the law of conservation of mass – lab Monday. Come prepared – be sure to read so that you’ll know what you are doing! You’ll only have about 12 minutes for Part 1 then you’ll finish Part 2 in class on Monday!!
Good job on the Mass without a Balance Lab!! Lab report is due Saturday midnight, submitted to Google Drive and Turnitin.com as a PDF.
The thLab: Candle Observation will be a great way to review properties and changes. You’ll write that one on notebook paper and turn it in in class. Have fun and don’t burn anything down!!

Hey guys, how are you doing on memorizing the symbols of the elements? Here’s a great study aid from quizlet.com. In the bottom right corner, click on “Choose a Study Mode” and you can change the layout and study different ways. If you already know them, try “Learn.” If you are just beginning to learn the symbols, I’d try “Scatter,” then go to quizlet.com (or click on the bottom left where it says “Study these flash cards”) and try “Space and Race.” I LOVE that game. It really puts your brain in gear and is great practice!
BTW – There’s an app for that! Quizlet has an app, also Oresome Elements and Mahjong Chem are good apps for learning the symbols of the elements. And I’ll bet if you look, you can also find other apps to help you learn the elements.
Good luck learning them – and don’t forget, the elements you have to know are the elements with these atomic numbers: 1 – 58, 60, 61, 74, 76 – 95.

CHEMISTRY: We’re finally starting what chemistry is all about! Here’s the lecture from Friday 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! 🙂

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 it and it will click, I promise!
