Book excerpt: A hands-on introduction to computer science concepts for non-technical readers. Activities include word searches, mazes, "Find the Bug!" hunts, matching games, "Color by Boolean" (a twist on the classic Paint by Numbers), and more. The Computer Science Activity Book is the perfect companion for curious youngsters -- or grown-ups who think they'll never understand some of the basics of how computers work. Work through this brief, coloring book-like collection of fun and innovative hands-on exercises and learn some basic programming concepts and computer terminology that form the foundation of a STEM education. You'll learn a bit about historical figures like Charles Babbage, Ada Lovelace, Grace Hopper, and Alan Turing; how computers store data and run programs; and how the parts of a computer work together (like the hard drive, RAM, and CPU). Draw a garden of flowers using loops, create creatures with conditional statements, and just have a bit of fun.
