Today, in Honors Physics, we left behind mechanics (oscillating particle model) and made the huge shift to start the charged particle model (CPM). We started our exploration of electrostatics with the classic sticky tape lab. The students made careful observations and readily proposed a reasonable hypothesis for most of the observed behaviors. However, when I asked why the paper strip was attached to both the top and bottom tape, they were stumped. So, devising an explanation for that behavior became homework.
