Introduction

This lesson was crafted to help students better understand that the stuff we put in our water (and down our drains) does not disappear.

The goal of every Central San lesson is to help students think more critically about “what happens to our dirty water after it goes down the drain?”

Students can do this lesson themselves at home with the help of a grown up.

Or a teacher can schedule a virtual lesson for their students with one of our educators. In that case, read our Materials Page so everyone can get ready for our lesson!
