ACS Publishes Safety Alert

Robert H. Hill, Jr., Ph.D., Chair, ACS Committee on Chemical Safety asked us to post the following alert about the Rainbow Demonstration. I hope chemistry teachers will share the alert with their networks.

How Many Colors in Your Computer? Discovering the Rules for Making Colors

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.

CD Light: An Introduction to Spectroscopy

In this Activity, students use a CD to build a simple spectroscope. They use it to investigate how different colors of light interact with colored matter. This qualitative Activity could be used as a general introduction to spectroscopy and the concepts of complementary colors and absorbance.
