I use VSEPR theory and teach them the bonding angles, then have them construct
models with clay and toothpicks. I like clay and toothpicks because there are
no predrilled holes.... the studdents have to think about where the
toothpicks (repreenting bonds) go....
Do you use the ABE (or AXE) formula? I use that for non-AP college-bound
students.
Write if you need more infor

Subject: [Teacher-talkchemistry] Hello!
Hi,
I am new to the teacher-talk list so forgive me if I am miss-using this
learning vehicle. I am a 2nd year high school science teacher from WI. I
am working on getting licensed in Chemistry, therefore I am taking the
course: "Reactions in Chemistry." I am taking the workshop/course
individually so I would like some input from others on some of the
coursework for the workshop.
I have viewed Workshop 1: Atoms and Molecules. I am now trying to work on
some of the homework assignments before viewing session 2. I thought there
was some useful information in Workshop 1. I agreed with the forum of
teachers in that students must understand atomic structure before they can
fully understand more complicated concepts in chemistry. Without this
foundations students will have a hard time understanding why particular
events in the chemical world occur. I thought there were some good
activities discussed to develop this understanding of atomic structure and
the periodic table. One area I would like to learn more about is teaching
students how to build molecules correctly and understand the geometery of
molecules. This is difficult for students to visualize because the
three-dimensional molecules are usually represented in two dimensions. I
think activities such as the balloon molecular structure or computer
simulations can provide excellent visualizations for this topic.
Please feel free to comment or ask me any questions. :)
Josh
