Waves and Electromagnetic Radiation
The term spectrum, first used to refer to the range of colors observed through a prism, is now applied in physical science to any signal that can be measured or decomposed along a continuous variable.

Students learn about colors, prisms and light, and draw their own rainbows in the proper color sequence.
Students conduct a discovery activity that allows them to observe how energy from sunlight can heat water.
