3D Sym Op

None

Description: 

This is a great app that helps students see the symmetry in molecules. It allows you to choose a molecule (by name, structure, or point group) and display a 3D rendition of it. You can then have it display the symmetry elements, and/or apply all the symmetry operations. 

It is available for both android and apple phones: (probably easier to just search for it)

Topics Covered: 
Prerequisites: 
Learning Goals: 

A student should be able to find symmetry elements in molecules. 

Corequisites: 
Implementation Notes: 

In class I project my phone screen so they can see it, and I encourage the students to work along with their phones. I prefer this to models, as it is hard to remember what things looked like before you did the transformation, and moreover, my students have a hard time finding the symmetry elements. 

 

I encourage the students to play with it anytime they have a few spare moments- waiting for the bus, in line for food, etc.
