<p>This is an in-class activity I made for my students in a Junior/Senior-level one-quarter inorganic course. </p><p>Unfortunately it was waaay too long for the 1.5 h class (i gave them about 45 min). I recommend taking this and adapting it to a take-home exercise or homework set, which is probably what I will do this coming year. </p><p>Students used Otterbein to look at various structures, starting with low symmetry, working up to very high symmetry structures. I had them go through the "challenge" so they couldn't see the keys at first, but then go back to check their answers. </p><p>Before class, I had students watch a TED-talk video on symmetry (see web resources) and lectured for about 45 minutes on point groups and symmetry elements. They were also expected to read the chapter on symmetry from MFT. </p>
- Students will be able to visualize chemical species as 3-dimensional objects
- Students will practice identifying symmetry elements of chemical species
- Students will practice determining point groups of chemical species
- Students will practice recognizing molecules of low and high symmetry
I ran this activity in a computer lab. You need internet connection and computers with the proper specs to use Otterbein. Students could bring their own laptops to do the exercise.
Give your students plenty of time, or make this a take-home assignmnet/homework assignment. Stuedents did enjoy this and found it very useful compared to just work on a flat surace.
