Chemistry 10-18-17 Conservation of Energy

CHEMISTRY – Happy Day!! We finished the chapter! Now it’s time to go apply what you’ve learned. Have you begun to think about ways you could separate that mixture? And what about a Plan B? πŸ˜‰

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™‚

Physics 10-18-17 Newton’s Law of Inertia

PHYSICS: Remind me again why didn’t that pen go flying across the room instead of dropping into the bottle? Hmmm…..

So what do you reckon is the inertia of this car? Great start today relating mass to inertia! Now go forth and apply what you know to find the mass of that spool of copper wire! Wait, did a say copper wire, I meant the mass of that unknown substance!

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

CHEMISTRY – Happy Tuesday! Here’s our overview of the elements and intro to the periodic table. Did you feel like it was mostly review?

How is the element handbook search going? You will be responsible for the information from Handbook Search 1 on the test. Tell enough to show what distinguishes that element as the type that it is – physical and chemical properties, where it can be found, what it’s used for, anything particularly unusual about the element, but don’t go into minute detail – just the main facts. You for sure don’t have to copy information from all the tables in the book.

Here is the link for the video clips on copper, phosphorus, and silicon that you will need to watch for the Element Handbook Search and for the TEST!! www.periodicvideos.com. The information on these video clips will be on the test.

Speaking of the test, have you had a chance to check out the Chapter 1 Stuff to Know 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 10-16-17 Classification of Matter

CHEMISTRY: Here’s a mixture that looks like it might be worth investigating – bacon caramel popcorn! I mean, I like bacon and I like caramel popcorn, but bacon caramel popcorn? Hmmmm….

So now that you know about mixtures, could you figure out how to separate one? Keep these notes handy!

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?!?)

Physics 10-4-17 Motion Down a River and Kid on a Slide with a Water Gun – Relative Motion Revisited

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.

Need extra help? Help session tomorrow morning, Thursday, 7:20ish.

Chemistry 10-4-17 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!

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??

Physics 10-3-17 Angular Projectile Problems

PHYSICS – Great job today working through the monkey-hunter problem, and great start on the rocket problem – I think you’ve got it figured out? Maybe? I found an old vodcast that has more of that problem worked – might help. πŸ™‚

Do the problems make more sense now? Don’t give up on the next set! They are tough, but you can do it!
