Universal Specialties Ultraviolet Detecting Solar Beads with Lesson Plan, Pack of 250

Exclusive Universal Specialties lesson Plan Included! Watch white beads change to colored when taken outside the building! When returned they turn back to white. What causes the change? The beads contain pigments which react with ultraviolet light from the sun, even on a cloudy day. They also change with most classroom UV light sources. Students can make their own UV light detecting bracelet by stringing the beads on a pipe stem or on a strip of rawhide. Great for teaching UV awareness! Use the beads to test the UV blocking effectiveness of sunblock, sunglasses, windows, etc. Lesson activities are included. All beads are pale, off-white in the absence of UV light.
