Students watch a short time lapse video of a sunrise and complete a T-chart (I Notice/I Wonder), and the question, “How does light from the Sun and other stars travel through space to reach the Earth?”
Students watch a second video entitled, “What are Electromagnetic (EM) wave properties?” They explain properties of EM waves and learn about the mathematical equation to describe the relationship between wave properties and energy.
Students then construct a spectroscope, which they use to analyze light. They also use the EM wave equation (v = f X lambda). They will observe UV beads that glow in the dark and then make bracelets with those beads.
