This is a complex activity that may encourage students to wonder why, but It builds on a more complex set of content ideas than I would use. The everyday background know may not spring directly from everyday experience and as such, the content may hinder rather than enlighten understanding.I would use this offering more as a deeper hands-on inquiry rather than as a demonstration. To me, discrepant events challenge student thinking, as this one may, but the event is simple and builds more on what students experience in their daily world and need to explain. Discrepant events are most effective when they are simple and relatively straight forward, stemming more from everyday experiences. They are great when the confound students but easily lead up to those little 'ahas' that ladder understanding in science.
