This is a three part lesson which begins with familiarizing students with SI prefixes and the nanoscale. In Lesson 2 students test a local water supply. It is designed to be used as an extension to classroom activities related to treating foul water for consumption. This activity should be done after students have been introduced to the concept of nanoscale and before Lesson 3 - Water Filtration and Nanoparticles lab. In Lesson 3, students make and test a sand filtration device to determine if they can filter out extremely small pollutants.  The device was used by students and the teacherto filter water in Mexico and Africa.
