Books in Everyday Mysteries: Leveled Readers Science series

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! But 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!

The ancient Chinese began making paper about 2,000 years ago. The basic process they created has been used throughout history. However, paper companies today use machines and can make a lot of paper at once instead of just one sheet at a time. Readers track papermaking from cutting down trees and making pulp with the wood to the final product we can use for writing. Full-color photographs show the papermaking process step by step, and an illustrated diagram simplifies it further for readers to review after reading the main content.
