This is a computer-based activity intended for a bioinorganic chemistry course composed of upper-level undergraduate students. It is helpful for students to be familiar with concepts of electron transfer, including a surface-level introduction to Marcus theory and the inverted region, and photosynthetic charge separation before beginning this activity. However, this activity can easily be adapted to students with other levels of preparation in a bioinorganic course.

This is a digital "escape room" where students determine point groups of molecules and answer follow-up questions to determine four digits. The four digits can be used to unlock a physical lockbox which is brought to class with small prizes inside.

In this activity, students will collectively build molecular orbitals for homonuclear diatomic molecules using balloons as models for atomic orbitals. This activity gets students up and moving and involved in the building of an MO diagram and allows for 3-D visualization of the core concepts of building molecular orbitals from atomic orbitals.
