The book has beautiful step-by-step, highly visual instructions and child appropriate materials, included in this kit, encourage independent learning through play, and lead a child successfully through each invention. Although Inventions is designed for children 8 years and up, this title has had an extraordinary history and following. It has been used at MIT to mentor high school students in physics.
