Sunscreen Evaluation 4-218

Target Grades: 4-8

Students determine the relative effectiveness of sunscreens with different sun protection factor (SPF) ratings and compare their own sunscreens against the standardized samples provided using a laboratory procedure rather than actual human testing. Comprehensive instructor’s manual explains the different types of light waves, including the ultraviolet light (UV) categories; why UV light is harmful to skin; how sunscreens work; the biology of skin and how it protects us from UV radiation; molecular structures of common protective sunscreen ingredients; how Beer’s Law relates to sunscreens; and how SPF ratings are calculated. Includes sunscreen samples for SPF comparisons, but requires five additional commercial samples for testing. Designed for 24 students working in six groups of four.
