In your home, electricity runs the lights, television, toaster, and more. It's hard to even imagine what your life would be like without it.
Electricity is a form of energy.
Atoms are tiny particles that are too small to see. Atoms make up everything around us. The center of the atom has at least one proton and one neutron. At least one electron travels around the center of the atom at very great speed. An outside force, called voltage, can push electrons from atom to atom.
