Light up your classroom with fluorescent solutions! Under normal white light in the laboratory, these solutions appear colorless, yellow, orange and pink, but when the lights are turned off and a black light is shined on them, they glow—and with different colors than under the normal white light! Explore the concepts of absorption and emission of light with this enlightening demonstration. Teacher Demonstration Notes included.
Concepts: Fluorescence, absorption, emission, electronic structure, spectroscopy. Time Required: 10 minutes Chemicals Provided: Quinine, fluorescein, eosin Y, rhodamine B, and ethyl alcohol solutions Note: A black light is needed and available separately.
