Exploring the Spectrum
(View Complete Item Description)This activity introduces students to the visible light spectrum, and demonstrates what happens to the appearance of an image when certain wavelengths of light are blocked by filters or made visible using special tools. Students are lead through experiments with light and filters, demonstrating that the broader the range of the electromagnetic spectrum we can detect, the more information we gather about the universe. By completing this activity, students gain background information that is necessary for activities that follow this one. This activity is part of the "Cosmic Questions: Our Place in Space and Time" educator's guide that was developed to support the Cosmic Questions exhibit. Activities in the guide can be used in conjunction with, or independently of, the exhibt.
