Nikola Tesla was a physicist, scientist, electrical engineer, and world-renowned inventor whose accomplishments faded into oblivion after his death in 1943. Tesla was undeniably eccentric and compulsive; some considered him to be somewhat of a "e;mad"e; scientist. But in reality, he was a visionary. Many of his ideas and inventions that were deemed impossible during his lifetime have since become reality. He was the first to successfully use rotating magnetic fields to create an AC (alternating current) electrical power supply system and induction motor. He is now acknowledged to have invented the radio ahead of Marconi. Among other things, he developed the Tesla coil, an oscillator, generators, fluorescent tubes, neon lights, and a small remote-controlled boat. He helped design the world's first hydroelectric plant at Niagara Falls. Nikola Tesla for Kids is the story of Nikola Tesla's life and ideas, complete with a time line, 21 hands-on activities, and additional resources to better understand his many accomplishments.

An Outstanding Science Trade Book 2017 Marie Curie, nicknamed "e;Manya"e; by her family, reveled in reading, learning, and exploring nature as a girl growing up in her native Poland. She went on to become one of the world's most famous scientists. Curie's revolutionary discoveries over several decades created the field of atomic physics, and Curie herself coined the word radioactivity. She was the first woman to win a Nobel Prize and the first person ever to win in two different fields-chemistry and physics.Marie Curie for Kids introduces this legendary figure in all her complexity. Kids learn how Curie worked alongside her husband and scientific partner, Pierre, while also teaching and raising two daughters; how this intense scientist sometimes became so involved with her research that she forgot to eat or sleep; and how she struggled with health issues, refused to patent her discoveries (which would have made her very wealthy), and made valuable contributions during World War I. Packed with historic photos, informative sidebars, a resource section, and 21 hands-on activities and experiments that illuminate Curie's life and work, Marie Curie for Kids is an indispensable resource for budding scientific explorers. Kids can: examine real World War I X-rays; make a model of the element carbon; make traditional Polish pierogies; and much more.
