The concept of time is hard to grasp. From a single minute to a full century, hearts beat, trees bloom and grow � and a human lives a lifetime. The book takes 18 different periods of time � from a single minute; to an hour; to over a century � to show the process of life, looking at biology in all its forms, from plants, animals and human biology too. In one minute, learn that your heart beats over 100 times. In one day, learn how a dragonfly unfurls a pair of wings. In a season, watch a bear hibernate for winter. In over 80 years, see a human live a lifetime. Packed with real science but rooted in the deeper things in life, this poetic non-fiction anthology is sure to prompt questions between a parent and child.
