Toot the Toilet Breaks Down


Toot the Toilet Breaks Down
Explorations with Engineering


Our dirty water goes down the drain.  

Guiding Question:

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

Lesson Description

Everybody knows that we don’t want a clogged toilet, not everybody understands what’s actually happening inside our drains. Toot the Toilet Breaks Down helps teach students all about what happens when their dirty water just won’t go down the drain and what we can do about it.

Toot the Toilet Breaks Down is a 1 hour classroom lesson, including hands-on materials and science notebooks designed especially for students to explore the physical sciences and engineering a toilet drain. The program will leave everyone with a deeper understanding of how a system they use everyday of their lives works and what it takes to keep it running smoothly. 


Aligned with 3rd Grade NGSS standards. Appropriate for K-8th grade.

3rd Grade: Forces and Interactions – Motion and Stability

3-5 Engineering Design

What Students Will Do:

Using our classroom-ready toilet models, students will attempt to “flush” any number of items down the drain to learn what happens. Some items might go down, other items might get stuck. Either way students will learn simple ways to avoid a mess. They will also get to use and evaluate different tools designed to unclog drains. 

What Students Will Figure Out:

  • That water is pushed through our toilet, not pulled, like it appears
  • 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 and time consuming to fix.
