In engaging stories about venomous animals, sinkholes, and a do-it-yourself submarine, Mara Grunbaum offered her young readers a look at how scientists and engineers seek to understand and interact with the natural world. She explained how erosion can carve out cavities in certain types of bedrock resulting eventually in a dramatic collapse called a sinkhole. But Grunbaum also sought to reassure her readers that the odds of being swallowed up in a sinkhole are very, very small. Her story on snakes and other venomous animals explained what makes snake venom harmful, how to counteract it, and how researchers are using ingredients of venom to treat disease. Her piece on 18-year-old Justin Beckerman described how he built a working submarine out of a piece of plastic drainage pipe. She explained forces, such as buoyancy and fluid pressure, that Beckerman had to understand before he could make a successful sub. The piece on Beckerman "skillfully draws you into a simply cool story while telling you important tenets of science," said judge Christine Dell'Amore of National Geographic News. Tina Hesman Saey of Science News said Grunbaum's piece on the submarine "seamlessly incorporates the failures inherent" in science and engineering discovery and "teaches concepts without ever bogging down the story." Grunbaum called the award a "huge honor," adding, "I love writing about science for kids — and I learn a lot in the process."
