During the Ejewels workshops, participants used a combination of basic electronics materials and basic craft materials to create jewelry with lights that glow, flash, and change color. These workshops enabled participants to become simultaneously engaged in a diverse set of investigations into: the nature of materials (for example, how light reflects against and refracts through different objects); the workings of basic electronics (gaining a practical, hands-on experience with serial and parallel circuits, short-circuiting, and the concepts underlying Ohm's law); and issues of personal identity (engaging in discussions of how jewelry reveals aspects of the wearer).
