Water Filtration and Purity of Water (Middle and High School curriculum lesson)

Linked product
Description
This activity—in which students test a local water supply—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 2 - Water Filtration and Nanoparticles lab. Students should have a good grasp of how to convert the size of objects to the nanometer scale.
