Time waits for no one and our lives are so ruled by time that it’s hard to imagine living a whole day without keeping track of it. In this colorfully illustrated book, young readers can learn fascinating facts about time and even imagine what it would be like to travel back in time. Did you know that Greenwich Mean Time is still calculated using the sun? That time of lifespans for different species greatly varies, like the Greenland Shark that can live for over 400 years and the mayfly that lives for only a few hours? These facts and more will intrigue curious young minds and budding scientists. 64 pages, hardcover. Ages 7 to 11.
