Our First Chem Day

Don't worry if you weren't in class today because you didn't miss much. We went to the auditorium and watched an episode of the Discovery Channel show Mythbusters. The episode, from the fourth season of the show, was called "Crimes and Myth-demeanors". We filled out a worksheet for it, but I  imagine that it wouldn't hurt your grade if you weren't here.

While Mythbusters is a good show, we missed you Ms. Friemann!

If you didn't finish your homework this weekend, you do have utnil tomorrow to get it done.

Balancing Equations in a Musical Fifth Period

Beginning of class

Mrs. Friedmann showed us a video of Mr. Lieberman singing “Friday” originally recorded by Rebecca Black as we walked into class, and comments about it lead to people talking about their favorite musicians. We went down the columns of desks for the first twenty minutes of class telling Ms. Friedmann (who took notes) about our favorite artists and songs.

If you weren't able to fully appreciate this wonderful rendition of the then thirteen year old one hit wonder's viral song, it can be enjoyed here:

Law of Conservation of Mass

After that, we took notes on the law of conservation of mass. Ms. Freidmann’s notes can be found here: http://gbs-moodle.glenbrook225.org/moodle/file.php/12015/1314_Unit_3/Unit_3_Notes/10.4_Notes_on_Balancing.pdf

I originally planned to write my notes from class here, but since the ones on moodle are superior, I think it would be unnecessary and redundant. It’s important to remember that atoms in a chemical reaction are neither created nor destroyed, only rearranged (and therefor “conserved”). In other words, the atoms in the reactants must match those in the products.

End of Class

After practicing a few balancing problems from the homework, we watched a video on German and the music video for the Ylvis song “The Fox (What does the Fox say?”. If you’d like to see either one again, I’ve posted the links below.
