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

Posted on by

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

Posted on by

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
