Diffraction Action Students will use diffraction gratings to view the colors or spectrum produced by visible light. Students will hold the diffraction grating in front of different light sources. They will record on their student page or in their Science Notebook the colors that they see when they view different types of light using the color chart that you provide or that they copy. Students may notice the intensity of the colors and the width of the color band produced. Students will be testing various materials to determine whether they are transparent, translucent or opaque.
Students hold the different materials in front of a light bulb.
They will then record the name of the material under the appropriate column on their student page or in their science notebook. Students will think of practical applications for the materials that they have observed. They will then describe any similarities or differences observed in the color spectrum with that observed at the diffraction action center. They will divide each circle into 8 equal wedges. On the first circle, color every other section red and blue.
