How could a smarter electronic alarm system make life easier for your friends or family? Great inventors use a process called design thinking to help them identify problems, big and small, and create solutions for them. This book introduces readers to design thinking and asks them to imagine an alarm system that might keep out a snooping sibling--and then design it themselves. Design thinking fosters innovation, creativity, and even empathy--essential learning for students. Book includes table of contents, glossary of key words, index, author biography, sidebars, infographics, and instructions.
