After laying down seemingly miles of copper tape–practicing complicated bends and turns–the fourth graders at Hannah Gibbons were ready to see if their skills could be applied to complete circuits and illuminate tiny LED lights. They masterfully wired a simple circuit, and celebrated 100% success as a class on their first try, each of them rewarded with the soft glow of a single LED light. Eager to master multiple lights, they dove into their parallel circuits with equal success and much enthusiasm.
Next up, we’d really investigate the line as well as our understanding of circuits. [Remember our Essential Questions regarding the line in this semester’s artist book residencies incorporating circuits and LED lights] Students each created a unique drawing of a robot that they invented through a creative writing exercise. With their completed drawings, students identified several areas where lights could enhance their robot illustrations; think eyes, antennas, hearts, and laser hands. The robot drawings were completed on the outside surface of a folded lift-the-flap structure to allow for the creation of parallel circuits beneath the illustrations.
Students plotted out the placement of their lights, and got to work designing and creating their custom parallel circuits. This was a huge challenge, and as a result offered the greatest reward. After weeks of practice, students adapted and translated their understanding of circuits into a line drawing of positive and negative parallel but never touching tracks looping back to the power source to illuminate the lights beneath their illustrations. There was an excitement of challenge, mixed with a little head-scratching, many super tight turns with copper tape, and a few frustrated re-starts.
And then, it was absolute magic. Every student mastered a unique parallel circuit for their book spread, and then folded down their robot drawing to lay flat over the lights. “Oooh”s and “Aaah”s sounded out in a cacophony as students celebrated in both amazement and disbelief of how their robots lit up exactly where they had hoped; their smiles as bright as their lights!
