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.
