Building a geodesic dome or suspension bridge model has never been more fun! In this book presented by Scientific American, budding engineers are challenged to take on achievable, engrossing projects involving classic engineering principles. Earthquake technology, energy, mechanics, gravity, and other scientific concepts are also included and thoroughly explained in the background section preceding each project. Expansion suggestions appear at the end of some projects in the book, making them perfect for science fairs and school projects. A concluding section outlining the scientific method connects this STEM volume to science curricula even more.
