This is a three part lesson with the first lesson dealing with the metric system, SI prefixes and the nanoscale. In Lesson 2, students test a local water supply and 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 a sand and test a filtration device to test for extremely small pollutants. The device was used by the creator of this lesson to purify water in Mexico and Africa.
