Students can use the Dropper Popper to plan and conduct an investigation to compare the effects of different strengths or different directions of pushes and pulls on the motion of an object.
Students can use the Dropper Popper to design, test, and refine a device that converts energy from one form to another.
Students can use the Dropper Popper to plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.
Students can use the Dropper Popper to construct, use and present arguments or experiments to support the claim that when the motion energy of an object changes, energy is transferred to or from the object.
Students can use the Dropper Popper to develop a model or experiment to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.
Students can use the Dropper Popper to design, build, and refine a device that works within given constraints to convert one form of energy into another form of energy.
Using a Dropper Popper in combination with a ping pong ball creates a dramatic demonstration of energy transfer—and much more.
