In this activity, students make an Ultra-Violet (UV) light detector. One type of light radiating from the sun, called ultraviolet (UV) light, is visible to insects and birds, but not to humans. UV radiation helps us make vitamin D in our skin, but too much of it can cause radiation burns (sunburns) and skin cancer.
