It was a teacher workshop session filled with surprises, including trips to the darkness of the women’s (rebranded unisex) bathroom to see our lighted projects working. The workshop I gave last Friday for teachers in the Charlotteville, Virginia, city school system was a successful attempt to combine a basic electric light circuit with a pop-up card. We began working through a series of pop-up structures, then built a circuit made of a lithium battery, copper tape, an LED sticker light, and a sliding paper switch to turn the light on and off as the card opened and closed. With the addition of a pop-up, we achieved lighted campfires, buildings, and creatures. The challenge for the teachers now is to work this into a lesson on paper engineering and electronics for their summer school students. Thanks to the Noyce Foundation for funding this project and to all who participated!
