Chemistry 9-30-13 Classification of Matter

CHEMISTRY: Here’s a mixture that looks like it might be worth investigating. I mean, 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 9-30-13 Chapter 1 Test

HON CHEMISTRY: God bless you as you are studying for the chapter 1 test! Here’s our overview on chapter 1 from today. And don’t forget, if you are getting lost with everything you need to know, or if you’re not sure how to study, the Chapter 1 Study Suggestion Sheet on Edline (under the Tests tab) would be very helpfull!

Also, don’t forget about the copper, phosphorus, and silicon videos. You can find them at

You can do this – I believe in you! I’m praying for you!!

Chemistry 9-27-13 Law of Conservation of Mass Lab

CHEMISTRY – Great job on the lab this week! So did you “see” the Law of Conservation of Mass the first time you did it? The second time? What was the difference? Be sure and tell me about that in your conclusions.

Any questions about writing the lab report for Monday? Make sure you save it as a PDF to your Google Dropbox folder. I’m thinking it also might be a good idea to review the Digital Lab Report manuscript form.

Be sure and give me details in your procedure. What did you do differently in the second lab and why do you think it worked? Here’s the the format for Part 1 and 2 of the lab write up, just in case you didn’t get it in class: Conservation of Mass Lab Report Notes – UPDATED

Hon Chemistry 9-27-13 Mixture Separation Lab

HON CHEMISTRY: Pretty intense couple of days this week, huh? You know, I’m really proud of you! It’s one thing to be able to follow a set of directions, but it’s a whole other thing to be able to come up with the directions on your own! That’s a difficult thing to learn how to do, and you are doing a great job developing that skill.

Any questions about writing the lab report for Monday? Be sure to save it as a PDF to your Google Dropbox folder. It might be a good idea to review the Digital Lab Report manuscript form.

Be careful that you give me pertinent details on your procedure. Don’t be too general, give details. Also, if your plans changed, tell me that too. And then, after you write your own conclusion, don’t forget to include all Analysis & Conclusion questions after your own Conclusion – No Extension questions.

Physics 9-27-13 Relative Motion

PHYSICS – Happy Homecoming!! Wow, we finally made it to the end of chapter 3! I know your brain was mostly fried from all of your early morning homecoming activities, but did you catch on to relative motion?

You know, we’ve done most of 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.

In case you didn’t get them in class today, here are the answer to tonight’s problems. Help session Tuesday morning??

36) 4.11 m
37) 80 m; 210 m
43a) 10.1 m/s at 8.53° east of north; b) 48.8 m
44a) 14.1° north of west; b) 199 km/h
45) 7.5 min
46a) 23.2° upstream from straight across; b) 8.72 m/s across the river

Physics 9-26-13 Rocket Plans & Rocket Problems – #62

PHYSICS: So did ya have fun shooting rockets? Make sure you have your plans and a back up plan for next Monday. Let’s see if you can hit the soccer net!

Here’s the solution to #62. Wow! But, you know, I don’t think is super hard any more so than it just has a ton of little steps that all finally come together. Are you using the formulas or are you letting them use you? Use your formulas to tell a story. And make sure it makes sense!!

Physics 9-25-13 Golfball Problem Update!

PHYSICS: So were we right or was the book right? Yay! You figured it out!

Here is the solution to the golf ball problem conundrum. I love the way you were able to go back through the problem and analyze each step to see if it was actually legit. Good job – learn from that!

Hon Chemistry 9-24-13 Elements & Intro to the Periodic Table

(Okay this is weird! The post from yesterday evaporated!! So here goes again….)

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.

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?!?)

Chemistry 9-24-13 Chemical Changes & Energy

CHEMISTRY – Happy Homecoming! So how do you know if something is a chemical and change? Applications, applications! Make sure you can apply what you learned today. Ditto on the laws of conservation of mass and energy.

Good job on tracing the energy transformations from one form to another. Make sure you can apply all this on the test (and in life!). Did I mention that already?

Speaking of the law of conservation of mass – lab tomorrow! Come prepared!!

Physics 9-24-13 Angular Projectile Problems

PHYSICS – Great job today working through the monkey-hunter problem! So what happened with the last one that we worked? Was the book wrong or were we wrong? Why? Watch our discussion again and see what you can come up with. Bring me an answer tomorrow!

Don’t give up on them tonight! They are tough, but you can do it!
