Physics 9-21-12 Component Method of Vector Addition

PHYSICS – Great job today!! You conquered the graphical method of vector addition, you are also going to do a great job with the component method. Give yourself a chance to get used to it and it will click, I promise! Here’s the lecture from Friday.

Hon Chemistry 9-21-12 Elements & Intro to the Periodic Table

HON CHEMISTRY -Okay this is weird. Somehow I saved the physics lesson on vectors as our class from Friday, soooooooo… I’m posting a lesson from the past on the same subject. 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? Let me know how the element handbook search is going. Both 1 and 2 are due Monday. Watch the end of the vodcast if you have any questions about how much info to include. Tell enough, but don’t go into minute detail – just the main facts.

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 9-20-12 Classification of Matter

HON CHEMISTRY: Wow – you were busy today! Good job in lab. How much error did you have? Any questions about the lab report? Make sure to show your calculations after the observations/data table. Also, be sure and give a reason in your conclusion for any error you might have had.

Here’s the lecture on the classification of matter – we’ll finish up tomorrow with the characteristics of pure substances. How are you doing on the examples of homogeneous and heterogeneous matter? Here’s a question to think about, can you tell me three different types of homogeneous matter?

Chemistry 9-20-12 Intro to Chemistry

CHEMISTRY: We’re finally starting what chemistry is all about! Here’s the lecture from Thursday on the intro to chemistry. Tomorrow let’s talk about making applications with 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 – Have you started learning the symbols of the elements? Is that something you’ve had to do in your other classes? Don’t forget to check out the earlier webpost on It’s a great way to begin memorizing them! πŸ™‚

Physics 9-19-12 Intro to Vectors

PHYSICS – Hey guys, great job today on the intro to vectors – graphical vector addition, resultants, and the like. Have you done anything like this before? We’ll spend tomorrow practicing adding vectors graphically. Great start today – and thanks for letting me play with the cute little applet! Don’t forget your protractor and graph paper tomorrow!

Hon Chemistry 9-18-12 Energy

HON CHEMISTRY – Happy Wednesday! Great job on the first part of the conservation of mass lab! Are you ready for part 2? Don’t forget your goal – no error!

Here’s the lecture from yesterday on energy – the law of conservation of energy, endothermic/exothermic, and potential and kinetic energy. BTW – Can you follow the conservation of energy in bungee jumping?

Element Symbols Practice Quiz

Hey guys, how are you doing on memorizing the symbols of the elements? Here’s a great study aid from 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 (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 – Allison just told me there’s an app for that! Quizlet has an app, 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 actual elements you have to know are the elements with these atomic numbers: 1 – 58, 60, 61, 74, 76 – 95.


Hon Chemistry 9-17-12 Matter and Its Properties

HON CHEMISTRY – Hey guys, here’s the lecture from Monday. I think most of this was review for you?? Make sure you have the vocab down, and for sure, be able to apply what you learned today. Can you tell the difference between quantitative and qualitative properties, intensive and extensive properties, physical and chemical changes, etc.? Let’s finish talking about energy tomorrow, and then we’ll play with the conservation of mass!

Good luck studying for the symbols quiz tomorrow! Have you tried

UPDATE – Change in plans! Let’s do the quiz tomorrow and finish energy. We’ll do the conservation of mass labs Wednesday and Thursday. We’ll be off a day – go figure! I want to make sure you have enough time for the lab. See you tomorrow!

Hon Chemistry 9-13-12 Intro to Chemistry

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 Monday. Don’t forget to check your syllabus for homework. You might want to go ahead as soon as you can and begin memorizing the symbols of the elements, as well as the atomic numbers and mass numbers for elements 1 – 30. Is that something you’ve had to do in your other classes?

Now it gets interesting!
