From building a bridge and crafting an automaton to making a guitar and creating a bubble tower, Smithsonian: STEM Lab is packed with activities that young readers can do at home to explore, discover, and understand the way the world works. How do boats stay afloat? How can seals stay warm in very cold temperatures? How can you make a ball levitate? With fun, hands-on projects and experiments, this book reveals how science, technology, engineering, and math are woven through the world around us. Simple steps guide readers through the stages of each project, with spotlights on the key science, technology, engineering, and math learning involved in each project along the way. "Test and Tweak" sidebars encourage young readers to experiment and take their projects to the next level, developing their independence, initiative, and creative-thinking skills. With a focus on STEM subjects (science, technology, engineering, and math) across school curricula to prepare children for the modern world, STEM Lab inspires and engages inquisitive young readers. It's perfect for school projects, homework help, and firing up imaginations.
