A dedicated Physics Van driver accompanies each of the van activities, brings the equipment to the school, and helps the teacher prepare the classroom and conduct the activity. The van driver is a retired CPS science teacher who has experience working with a diverse group of students. Teachers choose to involve the van driver at different levels depending on the particular activity, the class size, and the level of comfort they have with the activities.

Some teachers conducting activities for the first time typically depend on the van driver to assist them in serving as facilitators. More experienced teachers often elect to have the van driver do drop-offs, in which the driver simply brings the equipment to the teacher and returns at a later time or day to pick up the equipment. Typically, drop-offs will occur after teachers have done the activity one or two times and are comfortable with the various aspects of the activity such as the physics involved and the equipment in the activity. As more and more participants become experienced with the activities, the number of drop-offs increases and the van driver is then available to serve more and more teachers and schools. This allows for the program to continue to grow even if the level of funding remains relatively constant.
