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.
