During the Great Depression, many people had to work long hours and were barely paid enough to survive. Cesar Chavez felt this treatment was unfair and worked to secure more rights.

How can dogs that sniff for excrement, urine, vomit, and mucus help protect animals from extinction? In the race to save endangered animals, finding solutions now is critical. Scat-detection dogs like Wicket, Tucker, and Orbee are conservation heroes and pioneers in a cutting-edge field of science. Canine detectives use their super sense of smell to locate the scat of target animals. From loose bear dung to gooey whale poop, scat can tell scientists valuable information about an animal’s sex, age, diet, and health—all without harming the animal or endangering the researcher.
Introduces Benjamin Banneker, a free black man of the eighteenth century who loved to learn and used his knowledge and observations to build a wooden clock, write an almanac, and help survey the streets of Washington, D.C.
One spider's search for a home of her own Each spring hundreds of spiders hatch from their egg sacs and begin their struggle to survive. They must protect themselves not only from predators, but also from their very own siblings! Ginger Wadsworth and Patricia J. Wynne chronicle the real-life drama of one spider as she eats, grows, spins a dragline of silk, and soars up, up, and away to find a home of her own.
Imagine a U.S. president on a camping trip! It seems unlikely today, but in May 1903, President Theodore Roosevelt dismissed his Secret Service men to go camping with John Muir, the world-famous naturalist. For three glorious nights and four days in California's Yosemite National Park, the two men talked about birds, giant sequoia trees, glaciers, as well as the importance of preserving wilderness for future generations. They slept under the stars, built blazing campfires, and enjoyed the beauty and the uniqueness of the area. Setting aside new national parks and monuments became one of the cornerstones of Roosevelt's presidency and was a direct result of this camping trip. Author Ginger Wadsworth and illustrator Karen Dugan carefully researched this true story, relying on primary documents and working closely with experts in the field.

Undergraduate research enhances the learning experience of students in science, technology, engineering, and mathematics. Undergraduate Research in the Sciences offers a groundbreaking and practical research-based book on the topic. This comprehensive resource addresses how undergraduate research benefits undergraduate participants, including those populations that are underrepresented in the sciences; compares its benefits with other types of educational activities and experiences; and assesses its long-term value to students and faculty as both a scholarly and educational endeavor. In laying out the processes by which these benefits are achieved, this important book can assist faculty and program directors with practical guidance for design and evaluation of both new and existing undergraduate research programs. Praise for Undergraduate Research in the Sciences "This meticulous, definitive study of the effects of working with a faculty member on research as an undergraduate confirms the overall value of the experience by taking us deep into the minds and actions of participants—both faculty and students. As a result we now have many more compelling reasons to get more students involved with research mentors and ways to optimize the benefits for all parties."—George D. Kuh, Chancellor's Professor and director, Indiana University Center for Postsecondary Research "This timely book offers a unique, comprehensive analysis of undergraduate research in the sciences, based on the voices of college students and faculty mentors who have participated in these voyages of discovery. As our nation struggles to train more scientists, this book will be a valuable resource for designing undergraduate research experiences that can build our country's capacity for discovery and innovation."—Arthur B. Ellis, Vice Chancellor for Research, University of California, San Diego "The text is written in a lucid and engaging style and will be a valuable guide to policymakers, academic administrators, and faculty members who want to find ways to engage undergraduates in the 'real work' of investigation."—Judith A. Ramaley, president, Winona State University "This book is a 'must-read' for anyone who directs undergraduates in research. It presents an impressive and rigorous body of work that brings fresh insights into the field of undergraduate research. The next generation of scientists will benefit greatly from the findings and recommendations!"—Jo Handelsman, Howard Hughes Medical Institute Professor, Yale University

Born to Draw Comics, a mixed-panel format picture book biography of Charles "Sparky" Schulz, creator of the beloved comic strip Peanuts. As a child, Charles split his free time between adventures outdoors with his friends and dog Spike, and daydreams and doodles inspired by the comics he loved to read. He longed to become a professional cartoonist, but saw his dreams deferred by unexpected challenges that laid ahead: military deployment to the European front of World War II, and the heartbreak of a family tragedy back home. Even so, Charles never lost sight of the hopeful joy of his early years and his love for Spike, both of which inspired PEANUTS. The comic strip went on to become the most popular and influential in comics history. For fans of Brad Meltzer’s New York Times-bestselling picture book biography of the Muppets and Sesame Street creator, I Am Jim Henson. Christy Ottaviano Books
