Jelly Filter Science: Exploring Color with Gelatin and Color Vision 

written by Rebecca Vieyra and Caroline Hall

This multimedia lesson, Part 3 of the AAPT Color Science trilogy, goes beyond color addition/subtraction concepts to explore the effects of color filters. It includes two activities: 1) A lab that features cups of colored gelatin for use as red, green, and blue "filters", and 2) An interactive PhET simulation to analyze how filters are used to selectively transmit or block particular wavelengths of light to produce a desired effect. Settings in the simulation allow learners to toggle between a single beam of light and scattered light particles, providing an effective way to visualize the particle nature of light.
