Based on the recommendation of a student, I showed the class this excellent video on fields produced by Minute Physics:
It introduces the concept of fields and the historical background of the discovery of that model, even introducing the concept of scalar and vector fields. I love the particles of cheesecake passing through space field! It also serves to introduce the class to Minute Physics if they are not already familiar. (Although I hope by now that they all are!)
Students completed a practice quiz on the concepts of electric forces and fields. I need to follow up with a handful of students who struggled on the quiz and ask if they are struggling to understand the concept of an electric field or if they didn’t carefully read one of the questions and thought they were to be solving for the electric force instead of field.
