Drain Rangers Elementary Stormwater Curriculum (Grades 3-5)

In this unit, students will be introduced to a problem-solving model where they think like an engineer and explore ways to solve the problem of stormwater pollution. The lessons in this unit are specifically designed to meet classroom requirements of the Common Core and Next Generation Science Standards.


Content about polluted stormwater runoff, engineering design, and literacy skills are integrated throughout the unit so that students can practice and apply the new standards with relevant content. Polluted stormwater runoff is one of many environmental problems our students will face.


By equipping our students at a young age with the problem solving tools of the engineer and the verbal and written skills of an effective communicator, we are preparing these students to solve the difficult and challenging environmental issues that affect our present and our future.
