Kinetics and Equilibrium

Introduction to Kinetics and Equilibrium Unit

Friday, March 7, 2014

Today's chemistry class was all about the "It's Friday" spirit. It all started with Ms. Friedmann and Kevin G. balancing on the edge of the counter with one foot. This demonstrated holding an equilibrium…

Instead of taking notes, Mrs. Friedmann thought it would be a good idea to demonstrate some bigs ideas of this unit by doing activities in the old pit. These activities involved the class following directions:

• We tried the have a balance between two groups of people; this was done by having the same number of people on a side, making it symmetrical. 
• We tried having a group of 11 and 8 and had a flow of people traveling from one side to other other. The same number of people walking from one side maintained the balance of 11 and 8 and was not symmetrical.
• We tried having the two balanced groups of people, but everyone was moving in constant motion on each side. After walking in circles for a few moments, we had still maintained a balance.
• We tried having two groups where one group had two people walk over simultaneously with one person from the other group. This switch-up eventually led to one person on one side and the rest of the class on the other. This ended up not maintaining the balance because a different number of people from each side walked during each pass.

Lessons Learned:

• What comes in, must go out
• Equilibrium does not mean symmetrical
• Chemical reactions may appear as if doing nothing but is maintaining equilibrium
• Dynamic Equilibrium always moves, but is also always balanced

Next we went back into the class, so Mrs. Friedmann could bring fire. I left class 5 minutes early, so if anyone wants to recap what happened there in the comments, that'd be great.

Homework:

1. 2 crash course videos that you need to watch and take BIG-IDEA-ONLY notes where this should only take up 2/3 or 1 journal page for both videos

1. Unlike the calendar, Mrs. Friedmann will NOT be having us do a web assign over this weekend, but will be assigned at a later date.

Summary for January 21st

The first day of the new semester!

By: Jordan C.

Mrs. Friedmann started off the class with her unique life-view on choosing next year's classes. She made it evident that the class levels should depend life's balance rather than doing everything possible. However, it is ultimately up to the student. She made a point to say her experience in college was overwhelming in the sense that she took 18 credits the first year on top of other rigorous activities. This led to fatigue by the end of the year. It is important to take into account the balance in classes for the upcoming junior year.

We then led off to the next part of class with some review notes on ionic bonding. The majority, if not all, was review from the first semester. This can be viewed on the Moodle page or using this link below. Her commentary went along with the notes quite nicely.

Notes

The next part of the class was time set aside to start on the homework. The homework is the following:

1) Complete the Intro to Ionic Bonding worksheet -- due tomorrow.
2) Complete the ChemThink tutorial and question set for Ionic Bonding. You have already done this ChemThink, so the program might not recognize that you've completed it for a second time. Don't worry, just complete it to refresh your memory on the fundamentals of ionic bonding.

As a side conversation, the decision has not yet been made on whether we will study nuclear or organic chemistry.
