This is a lesson about the electromagnetic spectrum. Learners begin by arranging a set of picture cards; in the discussion afterwards, this activity is related to the electromagnetic spectrum as an arrangement of energy waves. Next, using a clothesline to model a logarithmic scale, they add in the electromagnetic spectrum. Finally, learners conduct several simple tests to detect other types of radiation. This activity requires access to a sunny outdoor location and the use of ultraviolet light-sensitive beads.
