Yvonne Clark had an engineering spark—an instinct for figuring out how things worked. Broken lamp? She screwed, rewired, and wrenched until…light! Wrecked radio? She twisted, snipped, and hammered until…music! Clogged furnace? She picked, plucked, and cleared until…heat! When she grew up, Yvonne’s problem-solving power took her to NASA, where fellow engineers had a serious problem with the Saturn V rocket’s F-1 engine: It had hot spots—high temperatures in the engine. Can Yvonne Clark and her engineering spark solve the problem?

Celebrating the power of curiosity and the rewards of tenacity, this engaging biography introduces young readers to the field of genetics. As a rare female botanist in early twentieth-century America, Barbara McClintock never let other people’s notions of what was proper slow her down. When she faced doubting colleagues and unsupportive institutions, she drove across the United States, climbed through windows, and even slept in her laboratory to conduct her research. In so doing, she helped pave the way for future scientific discoveries that can cure diseases and save lives.
