p.08 Build a Simple Electric Motor [Place your name here] Score /100 Purpose To construct a device that transforms electrical energy into mechanical energy and to investigate the relationship between electricity and magnetism in an electric motor. Materials Build a simple electric motor. I have shared a couple of websites with instructions. There are other websites with instructions out there if you would rather use those instead. The science teacher at your school may be willing to borrow you some of the supplies if you do not have them available at home. https://www.youtube.com/watch?v=it_27NdKgmy https://www.exploratorium.edu/snacks/stripped-down-motor?activity=138&display=further https:/ationalmaglab.org/education/magnet-academy/plan-a-lesson/electric-motors https:/ationalmaglab.org/education/magnet-academy/watch-play/interactive/dc-motor https:/ationalmaglab.org/education/magnet-academy/watch-play/see-thru-science/how-dcmot ors-work Video Share a short video of your motor working. Make sure that you appear in the video (at least briefly). (50 points) Experiment Design an experiment using your electric motor. Describe your procedure. (10 points) Modify a single experimental variable (make something different about your setup) and monitor its effect on the motor. Label and record your data. (10 points) Generate a conclusion. (6 points) If you were not able to get your motor to work here is a DC Motor Simulation from oPhysics that you can use to design your experiment. Discussion and Analysis 1. Explain why the coil rotates in an electric motor. (3 points) 2. What effect does removing half of the insulation from one tail have? (2 points) 3. What are some main factors that are important in getting the motor to spin? (6 points)4. Why is a magnet needed?

Would plastic coated paper clips work in this experiment? Why or why not? (1 point) 6. Why would it be ineffective to use plain copper wire instead of magnet wire to build the coil? (2 points) 7. What are three variables that you could adjust to increase the speed or power of your simple electric motor? Explain how you would adjust them.
