The prairie and desert grasslands were home to a variety of animals, from small prairie dogs to huge bison. But in the nineteenth century, ranching and farming took hold in the grasslands, and over time many of the animals and plants vanished.Then, in the late 1980s, scientists discovered a region in Mexico where green and gold grasses still waved and prairie dogs still barked. The scientists understood the importance of this grassland ecosystem and the prairie dogs' key role in it. Could they now preserve the area and bring back its lost animals and plants?This moving nonfiction tale of environmental recovery builds on the success of the acclaimed Parrots Over Puerto Rico and The Mangrove Tree. Cumulative song text plus prose passages combine to celebrate North America s grasslands, their iconic prairie dogs, and the dedicated scientists who work to make the grasslands healthy again. Comprehensive backmatter makes this book perfect for classroom use, with text that hits both Science and Social Studies Common Core Standards. Teacher s Guide available at leeandlow.com."

    With illustrator Grace Helmer's quirky renderings of animals in the style of world-famous artists, Kahlo’s Koalas extends the basic counting concept in a simple, one number, one image per spread format that introduces the smallest children to their first concept of numbers, animals and art appreciation.

    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.

    But what if we took these big, hard-to-imagine objects and events and compared them to things we can see, feel and touch? Instantly, we'd see our world in a whole new way." So begins this endlessly intriguing guide to better understanding all those really big ideas and numbers children come across on a regular basis. Author David J. Smith has found clever devices to scale down everything from time lines (the history of Earth compressed into one year), to quantities (all the wealth in the world divided into one hundred coins), to size differences (the planets shown as different types of balls). Accompanying each description is a kid-friendly drawing by illustrator Steve Adams that visually reinforces the concept. By simply reducing everything to human scale, Smith has made the incomprehensible easier to grasp, and therefore more meaningful. The children who just love these kinds of fact-filled, knock-your-socks-off books will want to read this one from cover to cover. It will find the most use, however, as an excellent classroom reference that can be reached for again and again when studying scale and measurement in math, and also for any number of applications in social studies, science and language arts. For those who want to delve a little deeper, Smith has included six suggestions for classroom projects. There is also a full page of resource information at the back of the book.

    Some old-time scientists thought that because they were so big, all they could do was float in water. Boy, were they wrong! Even today, once-common notions about dinosaurs are being revised as new discoveries are made. This lively book about the perennially popular subject of dinosaurs offers fascinating insight into how certain theories were formed, and then how those theories were proved or disproved. It demonstrates that scientific thought is as creative as it is logical and invites budding scientists to come up with their own ideas.

    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.

    Each fall, while the city's inhabitants dine on steaks, salads, and sandwiches, the great white sharks return to California's Farallon Islands to hunt their favorite meal: the seals that live on the island's rocky coasts. Massive, fast, and perfectly adapted to hunting after 11 million years of evolution, the great whites are among the planet's most fearsome, fascinating, and least understood animals. In the fall of 2012, Katherine Roy visited the Farallons with the scientists who study the islands' shark population. She witnessed seal attacks, observed sharks being tagged in the wild, and got an up close look at the dramatic Farallons—a wildlife refuge that is strictly off-limits to all but the scientsts who work there. Neighborhood Sharks is an intimate portrait of the life cycle, biology, and habitat of the great white shark, based on the latest research and an up-close visit with these amazing animals.

    The peacock's flashy tail is a masterpiece of color and shape. A buzzing beehive is built of tiny hexagons. Even a snake's skin is patterned with diamonds.

     In Elkhorn Slough, an inlet on the California coast, seagrass grows healthy and strong in the shallow water. This healthy seagrass baffled marine biologist Brent Hughes. The scientist expected this estuary to be overrun with algae, causing the seagrass to die. Why was the seagrass thriving? As Brent investigated, signs pointed to an unexpected player helping to keep the seagrass healthy: sea otters! What do these top predators have to do with an aquatic grass at the opposite end of the food chain? Brent's discovery gave scientists insight into the delicate balance of ecosystems. Follow science in action as Brent conducts the research that led to this major discovery.
