In Science Education in the Elementary Classroom, I was able to complete a discrepant event. A discrepant event is an unexpected turn of events. It causes the observer to wonder why the event occurred as it did. It leaves the observer at a momentary, or longer, loss to explain what has taken place.
Attached is the form for students to complete (during the event), an explanation of why it works, and a take-home sheet to explain to parents what was demonstrated during the discrepant event.
This discrepant event is related to Science SOLs: k.5c and 1. 3c
