Have you ever thought about what really happens when you flush a toilet? In this book, students will learn all about this quirky subject and the different parts of this simple machine. From the bowl, the tank, the handle, and stopper, students will learn all about something we all do on a daily basis but don’t really ever think about. So, next time you flush, you’ll know exactly what happens! This book will allow students to develop a simple sketch, drawing, or physical model to illustrate how the shape of an object helps it function as needed to solve a given problem.
