Summary: 

Make a geodesic dome big enough to sit in. Solve the world’s hardest two-piece puzzle. Pass a straight line though a curved slot. From prime numbers to paraboloids, activities in Amazing Math Projects You Can Build Yourself introduce you to the beauty and wonder of math through hands-on activities.

Learn by building, playing, and doing. Cut apart shapes to discover area formulas, build beautiful geometric models to explore their properties, and amaze your friends with the mysterious Möbius strip.

Throughout the book,  there are examples of how we encounter math in our daily lives. Marvel at the mathematical patterns in snowflakes and discover the graceful curves in the Golden Gate Bridge. You’ll never look at soap bubbles the same way again!

Amazing Math Projects You Can Build Yourself includes projects about number patterns, lines, curves, and shapes. Some activities show you a new way to look at math that you have learned in school; others give you a glimpse of things to come; and finally, some are simply fun. Each activity includes intriguing facts, vocabulary builders, and connections to other topics.

Myths and Legends: 25 Fascinating Projects You Can Build Yourself

Front Cover: 
Summary: 

From the Greek legend of Atlantis to West African creation myths, kids will discover the common themes and important knowledge conveyed by each story. They will even learn about the current events upon which some legends may have been based. Exploring the stories from many cultures, including those of Greek, Sumerian, Incan, Irish, African, and Native American people, readers will learn about the Celtic roots of Halloween, the beliefs and practices of voodoo, and the ancient Egyptian gods of the afterlife.

Hands-on activities bring the myths and legends to life, and help kids understand the cultures and traditions of the people that told them. Easy-to-follow projects use common household and recycled supplies, and include fortune telling, creating musical instruments, writing in ancient scripts, and fashioning a boomerang.

Review: 

GEEKDAD Wired Magazine April 28, 2010 World Myths and Legends can quickly become a favorite due to it being about some of the most exciting and fantastical stories in existence. I’ve had this book for several weeks and we’re not even 25% into completing the crafts.,, I haven’t seen my nine year old excited about a book like this for a while.

 

Charlotte Library 5/10/10 —Although this book might sound like a fairly ordinary craft book, it is much more--it is also an excellent introduction to the cultures and myths of a diverse selection of peoples, and one I highly recommend to home-schoolers in particular. . . The projects themselves are extremely varied, and go beyond simple craft-ness. For instance, one activity for the Greek section is to use Euclidian geometry to make an equilateral triangle--fun with compasses!  The point is that these are rather cool projects, such as I have never seen elsewhere.

Endorsement: 

“A remarkably comprehensive, accurate, and thoroughly readable overview of world mythology and legendry. World Myths and Legends will build a firm foundation for the
subsequent study and appreciation of this most important aspect of the human condition, and also lead to many hours of creative family fun.”— C. Scott Littleton, Professor of Anthropology, Emeritus, Occidental College, Los Angeles, California, author of The New Comparative Mythology

“This book is a terrific introduction for children to the subject of myths and legends. I cannot imagine a work that would more readily win the interest of children in the subject.”— Robert A. Segal, Sixth Century Chair in Religious Studies, University of Aberdeen, author of Myth: A Very Short Introduction.

“Sophisticated and fun.” — William Hansen, Professor Emeritus of Classical Studies & Folklore, Indiana University, Bloomington, Indiana

Activity Description: 

The name “daruma” comes from the Buddhist word dharma. Dharma is the truth about the way things are and will always be in the universe or in nature. According to legend, a Buddhist monk sat for so many years meditating that his arms and legs stiffened up. From then on, he rolled from place to place spreading the teachings of Buddha. In Japan, people buy daruma dolls on New Years’ for good luck. The dolls come with blank eyes. To make a wish, you put a dot in the daruma’s left eye. If it comes true, you fill in the other eye.

Amazing Africa Projects You Can Build Yourself

Front Cover: 
Summary: 

All eyes will be on Africa in 2010 when South Africa hosts the Soccer World Cup, an athletic event that rivals the Olympics in enthusiasm and anticipation. While Africa is one continent, it contains many diverse countries. Amazing Africa Projects You Can Build Yourself introduces readers ages 9 and up to the stunning landscapes, ancient civilizations and tribes, unique traditions, and amazing wildlife of the vast African continent.

Through 25 fun projects that use common household supplies and recycled materials, kids will beable to learn what life is like in Africa.

Review: 

Booklist May 15, 2010— Casual and informative, this large, attractive, browsable paperback in the Build It Yourself series offers a view of contemporary African life that reaches far beyond the usual scenery-and-wildlife tourists’ perspective. Blending history, culture, and tradition with politics and life in both cities and rural areas, the chapters begin with a look at natural wonders and dangerous wildlife that will grab readers, then move onto historical discussions of humankind’s birthplace and early civilizations. Views of daily life today show the continent’s vast diversity: in a city apartment, a teen might surf the Internet, but most Africans live in smaller, more rural communities, where there may be no electricity or running water. The author also discusses AIDS orphans, many of whom live homeless in the streets of shantytowns. The open design includes sketches on every page. Many readers may skip the craft projects––make your own Maasai beaded necklace, kente cloth, woven basket, galimoto doll, and much more––and go straight to the facts.

Endorsement: 

“User-friendly, clearly written, and grounded in deep historical evidence. The careful and compelling presentation on a wonderful continent allows us to reflect more clearly about an incredible place.” — Toyin Falola, University Distinguished Teaching Professor, University of Texas at Austin, and the Nelson Mandela Professor of African Studies-At Large.

“Amazing Africa Projects is a thoughtful, visually engaging overview of the diversity, complexity, and rich heritage of African people, places and predicaments. The book is a valuable resource for teachers and parents who want to encourage pre-teens to learn about and experience the past and present of Africa and to contemplate the continent’s future.”
— Dorothy L. Hodgson, Professor of Anthropology and Director of the Institute for Research on Women, Rutgers University

Discover the Desert: The Driest Places On Earth

Front Cover: 
Summary: 

Ever wonder what it would be like to visit the desert? Is it as dry and barren as it seems, or are there exciting discoveries waiting to be found? And how would you survive the extremes of temperatures, the rough terrain, and the vast distances? Discover the Desert takes readers ages 8 to 12 across breathtaking landscapes to explore the plants and animals of the desert, its lost civilizations, and today's desert-dwelling cultures.

Discover the Deserts wins 2010 Skipping Stones Award

Review: 

Skipping Stones Magazine Summer 2010—This fun-filled, easy-to-read educational gem will inspire you to explore the diversity of our world’s deserts through their unique climates, geography and ecology. But that’s not all! Among the engaging illustrtions you will find helpful vocabulary, fascinating facts, survival skills and fun at-home projects. It may even compel you to pick up a sandboard. Imagine snowboarding in the desert! Projects ideas include solar cooking, building an underground shelter, or planting an indoor cactus garden. Don’t forget, pack a copy of this book on your next expedition to the desert!

School Library Journal - 3/2010—Chock-full of definitions and facts, this exploration of deserts provides a lot of information about their location, formation, and characteristics.. . Produced to promote conservation of resources, the book includes illustrations and backgrounds in various shades of brown and gray, a logical choice for the subject… Those who peruse even some sections, though, can come away with topics they want to investigate in more depth by consulting additional sources, including the many books and Web sites noted at the end.

Wired Magazine, GeekDad- 1/2010 - Discover the Desert gives a great overview of deserts of the world, with plenty of specifics and important safety tips. You will come away with a much greater knowledge of what the world's deserts are like, culturally, meteorologically and biologically....the included activities and projects will be very memorable.

Booklist February 2010— This large-format book introduces deserts and helps readers imagine traveling through different types, observing their features, and coping with the challenges they present…. These relatively simple, hands-on activities will be useful to teachers and parents looking for ways to engage children with the subject.

Endorsement: 

“Deserts are the least understood among the land features of the earth because of their vastness and harsh conditions. Yet they remain one of the most fascinating regions of the earth, invoking mysteries and legends, especially in young minds. This book explains in simple terms the various features of deserts with practical lessons of how to travel in and enjoy that wilderness. Today’s young individuals are concerned about preserving the natural features of our planet. This book teaches them how to learn about and how to appreciate one of the most fragile environments on Earth.”
—Dr. Farouk El-Baz, renowned desert explorer, Boston University

“Children will learn a great deal about what deserts are like. I enjoyed Discover the Desert. Combines science with the excitement of discovery.” —Andrew Goudie, Master of St Cross College, Oxford, Emeritus Professor in Geography, recipient of the 2007 Geological Society of America’s Farouk El-Baz Prize for desert research

“Important concepts about the diversity of deserts, human habitation and use, and
geology are reinforced in a child-friendly and accessible manner. Discover the Desert
provokes excitement about a biome that has been traditionally and erroneously treated
as barren and devoid of life. Readers will be left with an increased understanding of the desert and, perhaps more importantly, an increased appreciation for the value of
deserts.” —Frank van Breukelen, Ph.D., Associate Professor, School of Life Sciences,
University of Nevada Las Vegas
