Program One: Because electricity is virtually unseen, it is often difficult to understand just where it comes from and how it works. Program Two: Magnets can be found in many objects that are used everyday. Not only are they located in man-made objects, but magnetic materials can be found in nature as well. In fact, the mineral, magnetite, was found to have magnetic properties long before humans learned how to make magnets on their own.
