Who was Grace Hopper? A software tester, workplace jester, cherished mentor, ace inventor, avid reader, naval leader—AND rule breaker, chance taker, and troublemaker. Grace Hopper coined the term “computer bug” and taught computers to “speak English,” and throughout her life succeeded in doing what no one had ever done before. Delighting in difficult ideas and in defying expectations, the insatiably curious Hopper truly is “Amazing Grace” . . . and a role model for science- and math-minded girls and boys.

    When a professor discovered that the homework sent to him under a male pen name came from a woman...nothing stopped Sophie. And when she tackled a math problem that male scholars said would be impossible to solve...still, nothing stopped Sophie.For six years Sophie Germain used her love of math and her undeniable determination to test equations that would predict patterns of vibrations. She eventually became the first woman to win a grand prize from France's prestigious Academy of Sciences for her formula, which laid the groundwork for much of modern architecture (and can be seen in the book's illustrations).Award-winning author Cheryl Bardoe's inspiring and poetic text is brought to life by acclaimed artist Barbara McClintock's intricate pen-and-ink, watercolor, and collage illustrations in this true story about a woman who let nothing stop her.

    Because she was going to study him, she decided to call him Alex--short for Avian Learning EXperiment. At that time, most scientists thought that the bigger the brain, the smarter the creature; they studied great apes and dolphins. African greys, with their walnut-sized "birdbrains," were pretty much ignored--until Alex. His intelligence surprised everyone, including Irene. He learned to count, add, and subtract; to recognize shapes, sizes, and colors; and to speak, and understand, hundreds of words. These were things no other animal could do. Alex wasn't supposed to have the brainpower to do them, either. But he did them anyway.Accompanied by Meilo So's stunning illustrations, Alex and Irene's story is one of groundbreaking discoveries about animal intelligence, hard work, and the loving bonds of a unique friendship.

    For example, the zebra gallops, the bumblebee flies, the lemur leaps and the tiger prowls --- ?But look closer now ... We all have STRIPES!? And so it goes. Again and again, readers will be surprised to find that a group of four seemingly different animals all have one trait in common --- whiskers, horns, shells and the like --- for a total of thirteen traits in all. Observant children will notice that one of the animals from each group also appears on the following spread with three new animals that have a different characteristic in common. Finally, all forty of the featured animals are shown together, and readers are asked to search for those with specific characteristics not already covered in the book --- for example, those with spots, those who live in the ocean or those with six or more legs. Author Heather Tekavec has discovered a fun and interactive approach to helping young children begin to explore the ways animals are classified. Pippa Curnick's playful and engaging illustrations of the animals in their habitats are all scientifically accurate, keeping the experience both enjoyable and informative. The searching activity also works to enhance visual literacy. With a detailed glossary included, this is an ideal book for introducing early lessons on the characteristics of living things and for starting discussions on the ways all creatures are like and unlike one another.
