What can you do to help endangered animals and make a positive change in our environment? Get counting! Counting Birds is a beautifully illustrated book that introduces kids to the idea of bird counts and bird watches. Along the way, they will learn about Frank Chapman, who used his bird knowledge and magazine Bird-Lore to found the first annual bird count.   Bird counting helps professional researchers collect data, share expertise, and spread valuable information to help all kinds of birds around the world, from condors to hawks to kestrels and more.   Counting Birds introduces kids to a whole feathered world that will fascinate and inspire them to get involved in conservation and become citizen scientists.

    Far from the thankless, pointless exercises they are often thought to be, mathematics and logic are indispensable guides to ridding ourselves of dominant opinions and making possible an access to truths, or to a human experience of the utmost value. That is why mathematics may well be the shortest path to the true life, which, when it exists, is characterized by an incomparable happiness.

    Capturing an engineer’s creative vision and mind for detail, this fully illustrated picture book biography sheds light on how the American inventor George Ferris defied gravity and seemingly impossible odds to invent the world’s most iconic amusement park attraction, the Ferris wheel.     A fun, fact-filled text by Gibbs Davis combines with Gilbert Ford’s dazzling full-color illustrations to transport readers to the 1893 World’s Fair, where George Ferris and his big, wonderful wheel lifted passengers to the skies for the first time.

    Arctic terns fly more than 10,000 miles from the South Pole to northern Maine. Tiny little hummingbirds fly nonstop over the ocean for 500 miles. How do they know which way to fly? Why don't they get lost? Read and find out the many ideas scientists have come up with to explain this mystery.

    It’s a fun way to learn to read and as a supplement for activity books for children.Why don't ducks get wet? Ducks dip and dive, but they stay dry because they spread oil over their feathers to make them waterproof. Learn more inside and get to know different kinds of ducks.  This is a Level One Let’s-Read-and-Find-Out Science title, which means the book explores more challenging concepts for children in the primary grades and supports the Common Core Learning Standards, Next Generation Science Standards, and the Science, Technology, Engineering, and Math (STEM) standards. Let’s-Read-and-Find-Out is the winner of the American Association for the Advancement of Science/Subaru Science Books & Films Prize for Outstanding Science Series.

    She springs over the treeline in hot pursuit--And then Zoe's mother calls, "WE'RE LEAVING IN FIVE MINUTES!"

If Julie works hard and saves her money all year, perhaps she can win the pony of her dreams--her very own Chincoteague pony.

    Topics covered in the book include the properties of arithmetic, exponents, primes and divisors, fractions, equations and inequalities, decimals, ratios and proportions, unit conversions and rates, percents, square roots, basic geometry (angles, perimeter, area, triangles, and quadrilaterals), statistics, counting and probability, and more! The text is structured to inspire the reader to explore and develop new ideas. Each section starts with problems, giving the student a chance to solve them without help before proceeding. The text then includes solutions to these problems, through which algebraic techniques are taught. Important facts and powerful problem solving approaches are highlighted throughout the text. In addition to the instructional material, the book contains well over 1000 problems. The solutions manual (sold separately) contains full solutions to all of the problems, not just answers. This book can serve as a complete Prealgebra course. This text is supplemented by free videos and a free learning system at the publisher's website.

    Together, the two set off to a place where countless owls circle the sky and snow flutters down from their wings. Recreated with graceful, precise brushwork, the majestic birds of Snow Moon seem poised to fly off the page. This story's lilting, lyrical text is just right for bedtime reading.

    In the winter of 1925, Nome, Alaska, was hit by an unexpected and deadly outbreak of diphtheria. Officials immediately quarantined the town, but the only cure for the community of more than 1,400 people was antitoxin serum and the nearest supply was in Anchorage—hundreds of miles of snowbound wilderness away. The only way to get it to Nome was by dogsled. Twenty teams braved subzero temperatures and blizzard conditions to run over 600 miles in six days in a desperate relay race that saved the people of Nome. Several of the dogs, including Togo and Balto, became national heroes. Today their efforts, and those of the courageous mushers, are commemorated every March by the Iditarod Trail Sled Dog Race. Jon Van Zyle’s stunning oil paintings capture the brutal conditions, pristine wilderness, and sheer guts and determination demonstrated by the heroic mushers and dogs.

    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.

    Now, at a moment when mathematicians are finally moving in on a proof, Dartmouth professor Dan Rockmore tells the riveting history of the hunt for a solution.In 1859 German professor Bernhard Riemann postulated a law capable of describing with an amazing degree of accuracy the occurrence of the prime numbers. Rockmore takes us all the way from Euclid to the mysteries of quantum chaos to show how the Riemann hypothesis lies at the very heart of some of the most cutting-edge research going on today in physics and mathematics.

    Scientist is friends with Viking. Pirate and Viking are NOT friends. What can Scientist do? Use his brain, of course--and the scientific method!
