Students are introduced to explorations into light and color in early grades,but it is important to continue giving these opportunities so they may develop an understanding of color as light waves are reflected, refracted, absorbed or transmitted through various materials.
NGSS Core Ideas: Electromagnetic Radiation
When light shines on an object, it is reflected, absorbed, or transmitted through the object, depending on the object’s material and the frequency (color) of the light.
The path that light travels can be traced as straight lines, except at surfaces between different transparent materials (e.g., air and water, air and glass) where the light path bends.
A wave model of light is useful for explaining brightness, color, and the frequency-dependent bending of light at a surface between media.
