Hon Chemistry 9-30-16 Elements & Intro to the Periodic Table

Posted on by

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?

How is the element handbook search going? 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. We’ll watch them in class on Monday, but feel free to go ahead and watch them if you’d like to get a head start! 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 9-30-16 Angular Projectile Problems

Posted on by

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?

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

Physics 9-29-16 Angular Projectile Motion

Posted on by

PHYSICS – So we are finally putting it all together – angular projectile motion! Here’s the lesson – some 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 9-28-16 Horizontal Projectile Motion

Posted on by

PHYSICS – Great job today – and applying stuff from the last chapter no less!

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!

Chemistry 9-28-16 Properties & Changes

Posted on by

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 9-28-16 Classification of Matter

Posted on by

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??

Chemistry 9-27-16 Intro to Chemistry

Posted on by

CHEMISTRY: We’re finally starting what chemistry is all about! Here’s the lesson from Tuesday. 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! 🙂

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

Physics 9-26-16 Review of Component Vector Addition

Posted on by

PHYSICS: So what do you this is the resultant of these “vectors”?!?

Great job with the component method of vector addition! My main take away from today – make sure you show all your work in a very orderly fashion! Here’s the review from today.

Hon Chemistry 9-23-16 Chemical Changes & Conservation of Mass

Posted on by

HON CHEMISTRY: More review today on states of matter and 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?

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!!

Physics 9-23-16 Component Method of Vector Addition

Posted on by

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!
