Science Buddies: Sliding Light: How to Make a Dimmer Switch With a Pencil

Curated by ACT

In this electronics science fair project, students will make a simple dimmer switch and investigate the relationship between the resistance in the circuit and the amount of light produced. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction, followed by a section on terms, concepts, and questions, bibliography, list of materials and equipment, experimental procedure, suggestions on how to vary the experiment, plus a focus on the sort of careers this experiment might relate to.
