The science and inventions that make us who we are . . . literally

Did you know the first blood transfusions were between people and lambs? Or that the first prosthetic hand with a hook was created so a French soldier could hold the reins of his horse in battle? Or that scientists recently grew a nose?

Invention & Impact, an exciting new series from PYRG-Smithsonian, introduces young readers to experiments, discoveries, and breakthroughs such as these, which have huge impacts on our world. Designed with exciting images from the Smithsonian's vast collections, each highly visual book in the series starts with a big idea and then explores that concept through specific objects that give kids the micro and meta picture on how inventions and ideas connect over time.

The debut book in the series looks at one of the most complex systems on planet Earth: the human body. From artificial eyeballs to aspirin to 3-D printed body parts, The Human Body profiles the objects that scientists and tinkerers throughout history have invented (or cobbled together) to protect, repair, or improve our physical selves. And there are plenty of fascinating stories behind these objects
