Kindergarten Pipe Protectors
Toot the Toilet



Our dirty water goes down the drain.  

Guiding Question:

What happens to our dirty water after it goes down the drain?

Lesson Description

Everybody uses the toilet, not everybody understands what happens after we flush. The Pipe Protectors program helps teach students all about what happens to their dirty water after it goes down the drain.

The Toot the Toilet pilot is a 1 hour classroom lesson, including hands-on materials and science notebooks designed especially for young students. The program will leave everyone with a deeper understanding of physical sciences, engineering, and how a system they use everyday of their lives works.

Enduring Understandings:

 At the end of the lesson, students will understand:

  • That only some things should be flushed down the toilet. Specifically Pee, Poop, and Toilet Paper
  • That when we flush other stuff down the toilet, it can create big problems that are difficult to fix.


Students will demonstrate their understandings though:

  • A conceptual model of their pre-thinking about what happens to stuff after they flush it.
  • A detailed diagram of what happens when they actually flush different items down our model toilet.
  • A summative assessment of things that are, and are not, appropriate to flush down the toilet.
