Why Lesson Planet?
Create models of the infrared, visible, and ultraviolet portions of the electromagnetic spectrum. Working in small groups, your class can investigate metric conversions calculations. They will find the length of the waves in nanometers, and then determine the size for the model of the spectrum if the scale is 1 nanometer equals 1 millimeter. They check their model by shining white light through a prism in order to see the visible spectrum.
