Light can be such an abstract idea for students. Rather than just read about how scientists study light, the goal for our skeptical 8th graders is for students to have hands-on experiences to see the "cool factor" and actually see why the study of light is so fascinating. Students will use diffraction patterns (Fraunhofer lines) to see how specific elements give off particular patterns on a spectrum of light. This method is how scientists determine what elements are in different stars. In addition, understanding these methods leads to understanding the movement of stars to or away from the Earth. The instructor already has a sample of element light tubes, but a new power supply is needed. In addition to using minerals like Ulexite (TV Rock) to study optical traits of rocks, students will look at fluorescence in rocks. The change in wavelengths affects how we (and different animals) can see objects very differently.
