Mixed format assessment (mutliple choice, fill in the blank, short answer) covering reflection, refraction, visible spectrum, waves and opacity.  There is a question at the end of the test over scientific investigation design and light.

 OVERVIEWThe Purpose of this lesson is to help students understand the concept that white light is a mixture of all of the wavelengths of the visible spectrum in roughly equal amounts. You can see beautiful colors everywhere you look! There is a lot of science behind the colors that you see. Color is the property that our eyes visually perceive and is derived from the spectrum of light. White light is a blend of all the spectrum colors which include red, orange, yellow, green, blue, indigo, and violet. Individual colors of white light can be seen by using a prism which separates the colors and, in turn, white light can be seen when the spectrum colors are combined in such a fashion as a spectrum spinner.  Each student will construct a spectrum spinner colored with the colors of the visible spectrum in order.
