What Happens When I Flush the Toilet? [PDF ebook] 

One person uses more than 20, 000 sheets of toilet paper each year. That means a family of four uses more than 80, 000 sheets. What happens to all that used tissue? Readers follow this and other waste through the toilet to discover this very answer. Full-color photographs and a simple graphic organizer aid readers’ understanding of this everyday process, including an accessible description of common waste management. Including a brief history of the toilet, the main content is written in accessible language for curious readers.
