Students can use the Energy Ball to apply scientific ideas to design, test, and refine a device that converts energy from one form to another.
Different proposals for solutions can be compared on the basis of how well each one meets the specified criteria.
A solution needs to tested, and then modified on the basis of the test results in order to improve it.
The Energy Ball can be used to develop and model how two objects interacting through electric fields, illustrates the forces between objects and the changes in energy of the objects due to the interaction.
Energy may take different forms.
Use the Energy Ball to test open and closed circuits or test conductors and insulators.
