Middle School – Water Treatment

Getting it Clean!


In this lesson, middle school students review the chemical makeup of water then dive into learning where the water we drink comes from and why and how it is cleaned. Armed with new vocabulary, students unscramble the terms of water treatment before they gather a few materials and work through the engineering process to design and build their own filter!
