  Question 7: Open-Response  
The picture below shows a battery-powered electric car. The chemical energy in the battery is changed into electrical energy when the car is being driven. The electrical energy is then changed into other forms of energy in the car.
Front view of a car. An antenna, windshield, windshield wipers, windows, mirror, door, tires, headlights, hood, and front fender are visible.
  1. Identify three parts of the car that use electrical energy.
  2. Describe how electrical energy changes into another form of energy in each part of the car you identified in part (a).
