When the sun's light shines through the earth's atmosphere, it collides with air molecules, which scatter some of the light.
Some colors scatter more completely than others.
In this activity you'll create a model to investigate the scattering effects of the earth's atmosphere on different wavelengths. Record your answers to questions on a separate sheet of paper. With your group, shine a flashlight through a prism. Turn the prism until a spectrum appears. Fill a container with water and shine a flashlight so that the light beam shines through the water.
