When I do this correctly, the students don't accidentally see something which may make immature students giggle.
I have had multiple colleagues tell me that this technique worked for them and saved them from repeating an embarassing classroom event.
The instructor will draw the bonding MO of dihydrogen without accidentally causing laughter in the class or self embarassment.

I have come close to accidentally drawing the incorrect version of this diagram and I am able to stop myself quickly as illustrated in the instructions.
During our first fellows workshop, the first cohort of VIPEr fellows pulled together learning objects that they've used and liked or want to try the next time they teach their inorganic courses.
This presentation is meant to be a review of constructing and utilizing an MO diagram, in this case O2. It's designed to be viewed as a powerpoint and printed out to keep for the student's notebook.
It can be used at multiple levels: as a review immediately after learning MO theory in general chemistry, or as a refresher before starting upper level inorganic chemistry. The instructure could add text or voice over the slides to add more detail or leave the presentation as is for students.
If you'd like .psd or .pdf files of the drawings in these presentation, please contact me directly.
After reviewing this material students should be able to:
Recall the shape, size and appropriate nodes of atomic orbitals.
Note the appropriate electron configuration of a given atom.
Draw molecular orbitals with the appropriate sign and node position.
Apply the Aufbau Principle to molecular orbitals to determine the ultimate spin state of a molecule.
Determine the bond order of a molecule from a completed MO diagram.
Manipulate the bond order of a molecule with Reduction/Oxidation.
I plan on uploading this flash review (along with others) to my class site before students arrive to my upper level inorganic course. I will voice over the slides, explaining the concepts, so they're ready to apply molecular orbital theory on the first day of class.
