"For fans of the "Who Was" series, this lively, accessible, and full-color chapter book biography shows how a self-taught scientist was the first to observe the microbial life in and around us. By building his own microscope, Antony van Leeuwenhoek advanced humanity's understanding of our oft-invisible world around us."-- Provided by publisher. Invisible organisms called microbes are everywhere: in soil, oceans, and snow; in the food we eat and the...

This book takes a look at the microscopic organisms, including mold and bacteria, discusses the causes of allergies, and looks at the invention of the microscope.

If you want to get a closer look at anything from a ladybug to a grain of sand, a hand lens or microscope is the tool for you. Handy explanations of measurements of magnification, such as 10x, are provided through accessible text. Practical tips about how to use and care for hand lenses and microscopes are also offered. Labeled photographs make the easy-to-follow text even more engaging and an experiment helps readers put what they have learned into...

On the Trail of Stardust puts the heavens in your hands-in the form of cosmic dust, or micrometeorites. With this handy guide from the author of the international bestseller In Search of Stardust, Jon Larsen, you will learn how to find micrometeorites in your own neighborhood! Stardust-also known as micrometeorites-is the oldest matter anywhere. Nothing has traveled farther to reach Earth. For a century, scientists have searched everywhere for stardust,...

Discusses the events and key figures behind the incredibly adventurous and treacherous exploration of the United States' western frontier.

Aliens live among us. Thousands of species of nonnative flora and fauna have taken up residence within U. S. borders. Our lawns sprout African grasses, our roadsides flower with European weeds, and our homes harbor Asian, European, and African pests. Misguided enthusiasts deliberately introduced carp, kudzu, and starlings. And the American cowboy spread such alien life forms as cows, horses, tumbleweed, and anthrax, supplanting and supplementing the...

"An illustrated picture book of early scientists Antonie van Leeuwenhoek and Galileo Galilei, who used similar observation tools but saw the world very differently, their discoveries leading to innovations in both microscopes and telescopes." -- Provided by publisher.

His goal: to bring a deeper understanding of "the American Sea" to students, scientists, managers, and educated citizens of the public at large. The American Sea builds on Darnell's own research, the research of his graduate students, government agency research reports, data synthesis reports, and literature summaries to present a holistic...

Annotation Reviews and synthesises emerging information on the evolutionary changes that occur in plants, animals, and microbial organisms when they colonise new geographical areas, and on the evolutionary responses of the native species with which alien species interact.
