Learn about the world of optics, where light bends to help us see the sights! Most of us rely on our eyes to see and understand the world. Yet, human eyes are far from perfect. Innovations such as glasses, goggles, and prisms have changed how we see the world. Light is the key to sight! Featuring a high-interest topic based on Smithsonian content, this book builds students' literacy skills while fostering curiosity, creativity, and innovation. It features a hands-on, minds-on STEAM challenge that guides students through the engineering design process: researching the issue, designing and testing a solution, evaluating the results, and improving the process. Through real-world examples, students will gain insight into how the engineering design process is used to solve real-world problems. This book includes content that highlights every aspect of STEAM: science, technology, engineering, the arts, and math. It also features STEAM career advice from Smithsonian employees working in STEAM fields. By becoming STEAM proficient, students are prepared to answer complex questions, investigate global issues, develop solutions for modern-day problems, and are ready for college and career.
