Sports Technology
After leaping from a plane, a skydiver opens a pair of carbon fiber wings and shoots through the sky at 200 miles per hour, in perfect control. Down on the ground, an Olympic pole vaulter soars to a world record on a state-of-the-art pole. A runner, born without feet, runs on space-age artificial limbs at speeds almost as fast as Olympic winners. Meanwhile, a swimmer slices through the water in a bodysuit modeled after sharkskin and shaves vital seconds off her time. How have these athletes managed such amazing feats? The answer is sports technology. Learn how science helps athletes stay safer, perform better, and have more fun. Book jacket.

Protecting Earth's Water Supply
From roaring oceans to trickling streams, water covers seventy percent of our planet! But did you know that less than one percent of Earth’s water is usable by humans? Most water on Earth is salt water. It can’t be used for drinking, bathing, or growing plants. We need freshwater. Yet about two-thirds of Earth’s freshwater is frozen solid at the North and South Poles. And the water we can access—from lakes, rivers, streams, wetlands, or underground sources—is in danger of being polluted. There is not enough water to waste. We must join together in the quest to protect this valuable resource. With engaging text and eye-catching images—plus a special Going Green section—this book tells you all about Earth’s water and what you can do to protect it.

Seven Wonders of Transportation
In every age, science and technology have advanced human civilization. From architecture to engineering, medicine to transportation, humans have invented extraordinary wonders. Transportation technology has seen significant changes over the centuries. Ancient people traveled on foot and on the backs of animals. People invented wheels and sailing ships, which helped them travel farther and carry larger loads. Fast forward to modern cars, subways, and airplanes and we’ll find that even the sky’s not the limit. In the twenty-first century, people are planning tourist flights into space. In this book, we’ll explore seven wonders of transportation. These wonders include roads and mass transit systems, including the ancient Silk Road, the London Underground, and the U.S. Interstate Highway System. The wonders also include vehicles such as bicycles, airplanes, spaceships, and the glorious ocean liner Queen Elizabeth II. The newest vehicles are “supergreen” cars, which save energy and help the environment. From the basic to the cutting edge, we’ll learn where transportation has been and where it’s headed.
