Now it is your turn to use the information you have gathered throughout this unit. Working by yourself or with a team, design a device powered by a battery. Use your imagination and what you've learned about electricity. Your device must use electricity to accomplish a task.

You will also:
Create a design log: Explain how your device will be used and how you figured out your design. Describe what worked best. What went wrong? What did you learn?

Draw a diagram of your device. Better yet, build a working model.
