Brain-Powered Lightbulb: Knowledge Transmission?by: Thomas O'Brien

Book ChapterDigital resources are stored online in your NSTA Library.

This activity explores the closed, battery-powered circuits that convert chemical potential energy to electrical energy to light energy. Since Edison’s invention of the lightbulb, it has been commonly used as a visual symbol of intelligence, ingenuity, and “bright ideas,” expanding on an ancient association of light with knowledge and understanding. As a visual participatory analogy, the message is that the teacher’s “light” cannot simply be given to students but rather serves as a spark to activate students’ attention and catalyze cognitive processing.

The old Adams Family light bulb is a great attention-getter for classes. Using that, you can springboard into the concept of light and electricity even further.
