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.
- Nanometer-sized things are very small, and often behave differently than larger things do.
- Scientists and engineers have formed the interdisciplinary field of nanotechnology by investigating properties and manipulating matter at the nanoscale.
- Nanoscience, nanotechnology, and nanoengineering lead to new knowledge and innovations that weren't possible before.
