NANOPARTICLES AND SUNSCREEN

Module Abstract

In this activity, students are introduced to the function of sunscreen and learn how nanoparticles can be used to protect people from ultraviolet radiation. They use photochromic paper as a UV sensor, place samples of different types of sunscreen over this UV sensor, expose their samples to UV light, and determine the level of exposure through each type of sunscreen. Using these tools, students compare the effectiveness of conventional (chemical-based) and nanoparticle-based sunscreens.
