Demonstration: Teacher will take students outdoors on a sunny day and: Keep this simple and short. Put water in a clear plastic tub. @ 10 minutes Place a mirror in one end at an angle facing the sun. Hold the white card stock outside the other end of the tub. Adjust the card until the refracted visible light spectrum is visible. Students will observe and make a quick draw in their science notebooks of the refracted visible light spectrum on the card. After returning to the classroom, students will improve and color their drawings. Groups will have an academic discussion of their observations and the reasoning behind it. Students will do a quick write in their science notebooks of their observations and the reasoning behind it. Activity: Teacher will show students a tube spectroscope Tube spectroscope kits are and discuss the process of its safe use without available from RAFT, which is using the Teacher could near the Santa Clara County word “spectroscope”. use the word to begin with and let Office of Education (SCCOE) “tube” students figure out the real word. Using white light from an incandescent bulb, Instructions for making tube students will look through the spectroscope and spectroscopes with are at: CD’s record the color patterns seen in their science notebooks. Teacher will change the white light bulb to a red bulb on the lamp. Students will again record their observations. Teacher and students will repeat the process with a green light bulb and an ultraviolet light bulb (black light). If the teacher has access to spectroscopes that measure the angstroms of the different colors seen in the spectrum, students will also record that information. Groups will have an academic discussion of their observations and the reasoning behind it. Students will do a quick write in their science notebooks of their observations and the reasoning behind it.
