The stars in the sky are part of our galaxy, the Milky Way. Scientists have tried to map the Milky Way for centuries, but it is hard! The Milky Way is so large, scientists cannot simply take a picture of it. Discover how they study the Milky Way, and learn about the galaxy that we call home. Featuring a topic based on Smithsonian content, this e-book builds students' literacy skills while fostering curiosity, creativity, and innovation. A hands-on STEAM challenge will guide 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.
