I created this activity as a way to get the class involved in creating new, fun ways to teach course concepts (selfishly- that part is for me) and for students to review concepts prior to the final exam (for them).  Students use a template to create a 15-20 min activity that can be used in groups during class to teach a concept we have learned during the semester.  We then randomly assign the activities and students work in groups to complete them and provide feedback.

The benefits are twofold:

This activity is designed to be done in the middle of the typical first quarter/first semester general chemistry electronic structure unit. Students will be expected to have learned the following concepts prior to completing this activity:

a) how the four quantum numbers are determined (principal quantum number, angular momentum quantum number, magnetic quantum number, and electron spin quantum number);

b) the basic concept of electron spin, and how atomic orbitals that possess two electrons will result in the spin-paring of electrons;

This is a flipped classroom module that covers the concepts of quantum numbers, and radial and angular nodes. This activity is designed to be done at the beginning of the typical first quarter/first semester general chemistry course (for an atoms first approach; if instructors use a traditional course structure this unit is likely done towards the middle/end of the first quarter/semester). Students will be expected to have learned the following concepts prior to completing this activity:

a) quantization of energy in the atom and the Bohr model of the atom;
