The Squishy Circuits team developed this activity so that young children (including my own daughters) would have a playful way to explore circuits. Squishy Circuits use two different types of dough as circuit-building materials—one that conducts electricity well, and one that does not. Both doughs are made with readily available ingredients such as flour and salt, and they can be prepared in a pot on the stove. Because of the playful nature of the dough, this activity is suitable for children of all ages.
About Squishy Circuits
The Squishy Circuits project is part of work done by the undergraduate research students in Dr. Thomas’ Playful Learning Lab at the University of St. Thomas School of Engineering. This lab, staffed by undergraduate research assistants, looks at ways in which engineering concepts can be explored through play. In particular, former students Samuel Johnson and Matthew Schmidtbauer were integral to the development of the Squishy Circuits project.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
