"How many seeds are in a pumpkin?" Mr. Tiffin asks his class as they gather around the big, medium, and small pumpkins on his desk. Robert, the biggest kid, guesses that the largest one has a million seeds; Elinor, sounding like she knows what she's talking about, guesses the medium one has 500 seeds; and Anna, who likes even numbers better than odd ones, guesses that the little one has 22. Charlie, the smallest boy in the class, doesn't have a guess. Counting pumpkin seeds is messy business, but once the slimy job is done... well, you'll have to read and find out!

    While others thought Jane would be terrified by the toy, she adored it and it inspired a life-long love of animals in her. Jane dreamed of a life spent working with animals, and when she was twenty-six years old, she ventured into the forests of Africa to observe chimpanzees in the wild. During her expeditions she braved many dangers and she got to know an amazing group of wild chimpanzees—intelligent animals whose lives, in work and play and family relationships, bear a surprising resemblance to our own. Through her work at Gombe Stream National Park in Tanzania and her own Roots and Shoots program she has become a tireless advocate for animals and the planet. As for that stuffed toy, Jubilee still sits on Goodall’s dresser in London.

    All around the world -- in the sea, in the soil, in the air, and in your body -- there are living things so tiny that millions could fit on an ant's antenna. They're busy doing all sorts of things, from giving you a cold and making yogurt to eroding mountains and helping to make the air we breathe. If you could see them with your eye, you'd find that they all look different, and that they're really good at changing things into something else and at making many more microbes like themselves! From Nicola Davies comes a first exploration for young readers of the world's tiniest living organisms.

    Puzzlists need only an elementary knowledge of math and a will to resist looking up the answer before trying to solve a problem.Written in a light and witty style, Entertaining Mathematical Puzzles is a mixture of old and new riddles, grouped into sections that cover a variety of mathematical topics: money, speed, plane and solid geometry, probability, topology, tricky puzzles, and more. The probability section, for example, points out that everything we do, everything that happens around us, obeys the laws of probability; geometry puzzles test our ability to think pictorially and often, in more than one dimension; while topology, among the "youngest and rowdiest branches of modern geometry," offers a glimpse into a strange dimension where properties remain unchanged, no matter how a figure is twisted, stretched, or compressed.Clear and concise comments at the beginning of each section explain the nature and importance of the math needed to solve each puzzle. A carefully explained solution follows each problem. In many cases, all that is needed to solve a puzzle is the ability to think logically and clearly, to be "on the alert for surprising, off-beat angles...that strange hidden factor that everyone else had overlooked."Fully illustrated, this engaging collection will appeal to parents and children, amateur mathematicians, scientists, and students alike, and may, as the author writes, make the reader "want to study the subject in earnest" and explains "some of the inviting paths that wind away from the problems into lusher areas of the mathematical jungle." 65 black-and-white illustrations.
