In science we are learning about electricity.
Electricity is one of the most important forms of energy in our world today.
Without electricity we would not have TV, Nintendo, or Sega, not to mention the necessities like heat and light. The basic unit of electricity is the circuit. We have also learned that if there is not a complete pathway the energy will not be transferred. An example might be if the wire is not connected to the positive and negative side of the battery then the circuit is open and the light bulb will not light. If there is a complete pathway the wire will be touching the positive and the negative sides of the battery, and the bottom and side of the light bulb.
