In-class small group activities are an integral part of the Paradigm Program. These activities are aimed at challenging the students to think of the physical phenomena they encounter in their daily lives. They are low tech and most experiments are not specified in a step-wise fashion. The primary goal of many of them is to make a conceptual leap, connecting key physics principles, through peer-lead interactions, previously learned physics and observations of natural phenomena. In most cases, the lecture covering the material is then given and finally connected to the activity.
