homework is another video!

same thing...leave a comment after you've watched the video.
I really enjoyed this video a lot.

When Chemicals Meet Water 

Really fine job on the show yesterday! Bravo!

Tomorrow, the Show

Homework is simply to be prepared for tomorrow's science show.  Please be on time, 9:10, so we can set up the room and ourselves and work out any problems.  Show starts at 10. Call me today if you have questions or supply needs.  We will just do our best, enjoy ourselves, and let the show go on!

Connor, I am supposed to bring you two things, could you remind me what they are? the thiosulfate and something else?

Ian, you still have time to come up with something, how about what we did with the steam and the  crunching pop can?  That would be impressive!  http://www.stevespanglerscience.com/lab/experiments/incredible-can-crusher

AVOID WEEKEND HOMEWORK...
WATCH TWO VIDEOS...
ONE ON TUESDAY,
AND ONE ON WEDNESDAY

or you can do it the regular way,
one before Thursday
and one before the next class (next Tuesday)

Same routine, watch video + leave a comment
                       watch the other video + leave a comment for that.


#1:  Unit 6: Quantifying Chemical Reactions—Stoichiometry and Moles

#2  Unit 7: The Energy in Chemical Reactions—Thermodynamics and Enthalpy

Today' homework (Friday) is another review/preview video. As before, leave a comment describing a section of the video in the comments below:
Unit 5: Making Molecules—Lewis Structures and Molecular Geometries

And here's my comment: At around 20 minutes in the video, the MIT chemist talks about what made her want to switch from becoming a doctor to becoming a chemist, and her words were these:

So, when I first studied penicillin, I was amazed, I said ‘Wow, like, so this, thinking about the structure right here is how we can actually understand how it works in the body. And this is the point for me where I started that switchover from thinking I want to help people by becoming a doctor to I want help people by studying and understanding how things work on a molecular level.

What stood out to me is her choosing a career based on how "I want to help people," not just what I like doing or what makes a lot of money or brings me fame, but how I can help...How great is that!



note: last period I received comments from Laura, Niles, Abigail, Connor and Zach.  Good job, to them, but I expect ALL of you to watch and make a significant comment.

Monday we will practice the chem show.  Bring in any extra items you will need.

Here's the video; after you watch, jot down a little bit about a section from the video, and leave it in the comments below, along with your REAL NAME:) Unit 4: Organizing Atoms and Electrons—The Periodic Table

Homework Today (Friday) is to watch another of these excellent REview/PREview videos; this one is on the electron and the atomic model.  One thing I did not cover in class is the relationship between electrons and light, which would be particularly useful to understand Mabel and Abigail's chemagic demonstrations.  Like last period, so that I know you have done your homework, write one sentence stating an important point from the video, and leave that, along with your name, in the COMMENTS below. I noticed only 4 people left comments last homework.

Unit 3: Atoms and Light—Exploring Atomic and Electronic Structure

For homework this period, we will continue the chemistry video series we began last week.  This series of videos is a REview/PREview; it recaps the major points we have studied (the first 15 minutes) and then it goes beyond that in interesting ways.  So the beginning of each video should be familiar, and the end might be a little complicated, but worthwhile.

So, lesson 2, Unit 2: The Behavior of Atoms—Phases of Matter and the Properties of Gases
When you have finished watching the video, please leave a comment stating one thing mentioned in the video, along with your name.

#2. Work on the dialogue (what you will say) to go along with your chemagic demonstration.




Please be at the Copperman's by 9:15 on Thursday.  HAVE YOU LEFT A COMMENT?

Three things:.

2. The CheMagic Show -- On Monday we will work on this in small groups, I will bring the supplies, as much as I know of, and you MUST bring a printout of directions for your act, and any props you need. Class still starts at 9:10, even if we start with 4square.  Don't be late.
3. ...and the homework, a video review of  first principles: http://www.learner.org/courses/chemistry/video/vidbyunit_1.html
30 minutes
4.  and also review-read chapter 25, sections 1&2, and read section 3 (no notes, but highlight/underline what you think you might want to  remember for a quiz)
