Product Description

This lab is an introduction to spectroscopy. I review the PPT and students take notes. After the second slide, I would draw the electromagnetic spectrum on the board and discuss the characteristics of light like wavelength and frequency for the different types of electromagnetic radiation. After reviewing, students complete the pre-lab questions. I pass out colored pencils (ROYGBV) to pairs of students to share. After the pre-lab questions are checked off, I have students look at the fluorescent lights in the ceiling using the spectroscopes or diffraction gratings, and we discuss how a continuous spectrum is produced. Students color in the example using the continuous spectrum from the fluorescent light, and I explain that they will color in the range at each lab station they visit. Different types of light sources are placed at eight different lab stations, for example, incandescent light bulb, red/green/blue light bulb, LED light bulb, light boxes with different gas tube, infrared light bulb, or halogen light bulb. I have even put out plasma orb lights or anything unique for them to try.
