This easy-to-follow book allows young learners to explore the inner workings of microwaves.
Did you know the microwave oven was actually invented by mistake? While experimenting with electricity, a scientist noticed the chocolate snack he had in his pocket actually melted. This led to the technology that has made cooking faster, more convenient, and used more than conventional cooking. This book addresses the differences between a standard oven, which uses conduction, and a microwave oven, which uses microwaves, causing food molecules to move, creating heat. This book will allow students to plan and conduct an investigation to determine the effect of placing objects made with different materials in the path of a beam of light.
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. Microwave Ovens 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.
