Kids are drawn to dolls and dump trucks, and crashing the two together might just be a child's favorite pastime. Who knew such a simple pleasure could serve as an accessible, compelling phenomenon for instigating investigations of force and motion. With a few inexpensive materials straight out of the toy box (literally, a doll, a dump truck, a ramp, and some weights), teachers can set up and facilitate a whole suite of Crash Test Physics investigations that are easily adaptable, and that have been effectively piloted in classrooms, festivals, and outreach events alike with student populations that range from preschool to pre-service elementary teachers.
