From armored tanks and gliders to "plastic glass" and drawing machines, this interactive book explores the incredible mind of Leonardo da Vinci through hands-on building projects and activities. Most of Leonardo's inventions were never made in his lifetime and remained sketches in his famous notebooks; kids examine some of these original sketches and learn about the models Leonardo made of his inventions. From there they delve into detailed step-by-step instructions, diagrams, and templates for each project, which are interpersed with historical facts, biographical anecdotes, and trivia. Most of the building can be done using simple household supplies: construction paper, tape, markers, glue, cardboard tubes, aluminum foil, and cardboard boxes. Background about the Renaissance as a period of remarkable achievement in art and science appears throughout the book.
