A working kaleidoscope, a marble roller coaster, a robotic hand, and a wind-powered tractor with cardboard gears are just some of the ingenious projects developed by Jonathan Adolph, author of the best-selling Mason Jar Science. Working with simple household tools, kids can follow the step-by-step photographic instructions to exercise their design smarts, expand their 3-D thinking, and learn the basics of physics and engineering with activities that have real-life applications.
he text features detailed instructions, diagrams, and background information on inventors and engineering areas. The introduction provides material suggestions, such as types of glue and the pros and cons of the various types of cardboard. Six chapters highlight projects that include robotics and animatronics, audio and optical engineering, aeronautics and nautical engineering, mechanical engineering, and harnessing energy.
