CHILDDRREENN’S’S A ACCTITVIIVTIYT/YE/DEUDCUACTAIOTNIO RNE SROEUSROCUER CE AGES 8 AND UUPP MORE THAN 50 VOLCANOES HAVE ERUPTED IN THE UNITED STATES IN THE PAST 200 YEARS. THE UNITED STATES HAS 93 NATIONAL MONUMENTS. REDWOODS CAN LIVE UP TO 2,200 YEARS, AND MAYBE LONGER! DISCOVER NATIONAL monuments, NATIONAL parks: natural wonders introduces readers ages 8–12 to the history and science behind some of the most amazing natural sites in our country that have been named national monuments. These natural phenomena have been created by the forces of wind, fire, water, and time. All of these monuments, many of which are now national parks, belong to everyone in America. Each has a fascinating story to tell about America’s past. Kids will learn about some big concepts, such as how a coral reef is formed, or what causes volcanoes to erupt. They can also explore these concepts with hands-on experiments that include making stalactites natural wonders and discovering how a river can erode rock into a canyon. By understanding the science behind the growth of a coral reef or the petrifaction process at work in fossil formation, kids will feel invested in the future of the natural areas where these phenomenon occur. History, science, culture, and a wow factor sure to get the attention of this age group will enlighten kids about the importance of safeguarding our world’s treasures. “C ynthia Light Brown truly captures the essence of America’s national parks and monuments. Her book combines lessons in history, geography, and science with conservation. Better yet, it opens the door to adventure and discovery for grownups and children to share about our country’s treasures. It makes us all better citizens.” —M ichael Frome, Ph.D., educator and author of Regreening the National Parks and other books “U p-to-date science provides engaging, educational activities for children, inspiring families to visit the hidden gems that are our national parks and monuments.” $19.95 —E rica Bree Rosenblum, Ph.D., Assistant Professor, University of Idaho ISBN: 978-1-9346702-8-6 “W ow—what a fun book! I absolutely love the “Try This” and “Make Your Own” sections that are liberally scattered throughout the book.

Each celebrates an important and unique facet of America. National monuments can be sites of ancient Native American cultures. ey can be battlefi elds, forts, or remarkable structures built to honor important Americans. Many national monuments celebrate and protect natural phenomena, created by the forces of wind, fi re, water, and time. is book focuses on this last group—some of the most amazing natural sites in our country that have been named national monuments. You’ll learn about the forces that shaped these places, and even try out some projects and experiments to learn for yourself about the processes at work.
