Create a UV Bracelet Activity

In this activity, learners create their own ultraviolet light detecting bracelet. UV beads contain a special material called a photochromic dye that change color when exposed to ultraviolet light. The activity is curated by the University of Alaska Museum of the North and allows learners to explore the electromagnetic spectrum, which consists of light energy travelling in waves, from very short waves like gamma rays to very long waves like radio waves. Ultraviolet, or UV light, has shorter waves than visible light.
