Pixel Tube

In this STEAM activity, learners create a "pixel tube" to explore reflections of light and color mixing. This device, made of rolled up shiny materials inside of a carboard tube, allows learners to see shifting shapes and patterns that are the result of reflected light mixing and mingling in interesting ways. Activity includes step-by-step instructions with pictures, an explanation of the science behind the activity, suggested extensions, and teacher tips.
