Static Electricity Discrepant Event

Discrepant Event Handouts

Discrepant events are scientific demonstrations that are used to engage young learners through the presentation of unexpected outcomes. This Static Electricity discrepant event was demonstrated in my fourth grade Practicum B experience during the Science block. The above link includes a handout for the teacher about how to conduct the demonstration, including needed materials, detailed steps, and safety considerations. The student handouts provide students with the opportunity to make a prediction about what will occur, as well as write about what actually occurred during the demonstration. For this demonstration, the students were able to understand that both a balloon and a comb could pick up, or attract, the positively-charged pieces of tissue paper because both items become negatively-charged when rubbed against someone’s hair to create static electricity.
