"This non-fiction picture book explores time and how we think about it in a different way - as a series of events in the natural world (some of them directly observable, others not) that take place in a given unit of time. Steve Jenkins' extraordinary illustrations will accompany this engaging look at time. Just a Second is visualized as a linear series of illustrations and captions, starting with a second, a minute, an hour, a month, and a year. What happens in a second? A gnat beats its wings 1000 times. A hummingbird beats its wings 75 times. A shrew's heart beats 13 times. A bat squeaks and listens for an echo 10 times. A dropped stone falls 16 feet. Earth travels 18 miles in its trip around the sun. A cheetah can run 100 feet"--
