Students may be slathered with SPF 30 sunscreen all summer at the beach or pool, but what do they know about ultraviolet (UV) light radiation and absorption? How could we help them find out the science behind this important health precaution? We found the perfect opportunity when we developed this series of practical strategies to promote students' investigation skills. We integrated several scientific processes into a lesson on UV light radiation and absorption for fourth-grade students and preservice elementary methods students. These teaching tools help students develop their abilities to ask testable questions, plan and design investigations, and interpret what they find.
