Circuits in Motion
What Will You Learn?
Let’s jump in and put some circuits to work. We’ll explore circuits and make a moving race car with a vibrating offset motor. For this project, we’re using the Lectrify Shake It Board which includes the motor, the battery pack, and a switch all in one piece.
This project is a sample from our Circuit Scouts Kit, available in the Maker Shed with all the materials you need, a guidebook and educator’s curriculum.
Make a Racer
Build your paper racer model.
Color your race car template as desired. (Note: Print at actual size. Do not “fit to page”. If desired, a template sized to 8.5″ x 11″ paper with two racers is available. An SVG for digital cutting is also available. Note that the length of the racer should be 7.125″ for the ShakeIt Board to fit properly.)
Assemble the paper template. (Figure 1a)
Cut along the solid lines.
Fold along the dotted lines.
Glue or tape the tabs into place.
Let’s add the motor and switch.
Slip the Shake It Board into the body of the racer.
Turn on the switch. (Figures 1b, 1c) What happens? Why?
Time to customize!
Gather materials such as drinking straws, pipe cleaners, paperclips, buttons, etc. Try making wheels or blades for your racer. How can you reduce friction so that the car moves more quickly? (Figure 1c)
Try adding weight to different parts of the car to see how it affects the motion. Does the weight of the car affect the motion? How? Why?
