Conduction Countdown

In this quick SciGirls activity (page 1 of the PDF), learners will be introduced to the concept of thermal conductivity. A metal knife and a plastic knife are each poked into slices of cold butter then placed handle-first into a glass of warm water. Learners predict which butter slice will fall first and watch carefully for the result. Relates to the linked video, DragonflyTV GPS: Doghouse Design.
