In this Activity, students investigate the colors displayed on a computer monitor with a magnifying glass. They then mix colors first using light, then using paints or crayons. This Activity could be used in discussions of solid state chemistry when LEDs, phosphors, or liquid crystals are discussed. It may also be appropriate when introducing spectroscopy because it deals with absorption and emission of colored light. It could also introduce a unit on practical applications of chemistry, such as the chemistry behind computers.
