This easy-to-follow book allows young learners to explore the inner workings of escalators.
This book discusses how an escalator is based off a conveyor system, moving objects up and down using gears. This form of transportation has made it more convenient to go from one floor to another without walking up flights of stairs. This book will allow students to analyze data to determine if a design solution works as intended to change the speed or direction of an object with a push or a pull.
Filled with full-color photographs and reading comprehension activities, this book effectively engages students and complements the research of how an important piece of technology works. Escalators allows students to make observations and gather information about a simple problem that can be solved through the development of a new or improved object or tool.
Each 24-page book features a teacher-focused concept, before- and after-reading activities, a photo glossary, and more, for a well-rounded understanding of the topic. The How It Works series lets young readers explore and research the technology and design of important, everyday things and how they are engineered. With simple-to-follow text and full-color photographs, these books easily engage young learners to discover the inner workings of complex objects and concepts.
