Lars Petersen believes in a hands on approach to teaching. The Biology instructor used the 3D printers in the Maker Studio to create two DNA models that help his students to understand genetics. One model is used as a teaching aid during his class lectures and the other breaks off into magnetized detachable pieces students use to work in groups and determine how to build the DNA helix. Petersen has said that even his own understanding of the appearance and functionality of DNA has been enhanced by playing with the models that took almost 6 months to complete.
