This activity allows people to spend time modeling the play-doh to create artistic sculptures. It also invites participants to use the material as a purely functional “wire” to conduct the electricity. But when those two combine, people begin to operate in the sweet spot between art, science, and technology.
Teaching Sequence:
Make simplified squishy circuit, such as in the above image
Insert nails into conductive clay pieces, connect to battery pack with clip leads
Insert LEDs into conductive clay- note directionality of LEDs
Review complex examples below, build, and test
Dozens of step-by-step building instructions
