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.

Have a nice weekend and don’t forget to do the ChemThink and
worksheets from class!
The next scribe is, as requested, Daniel W!
