Seals, otters, oysters, fish, pelicans, and sharks are a few of the animals that make up an ocean food web. But did you know that almost all ocean creatures depend on algae to live? Or that bacteria, crabs, and lobsters break down dead plants and animals into nutrients? See ocean food webs in action in this fascinating book.

Beetles, toads, squirrels, owls, deer, and black bears are some of the many animals that make up a forest food web. But did you know that leaves, berries, mushrooms, and tiny bacteria are also important? Or that humans can affect the health of a forest? See forest food webs in action in this fascinating book.

This book describes Neptune's most interesting features, its position in the solar system, its composition and atmospheric conditions, its moons, and how scientists have learned about it over time.

Outraged people claimed that Darwin's theory had made humans the relatives of monkeys. Scientists were sure that species changed over time, but no one could explain how. In the 1800s, Charles Darwin's studies of thousands of specimens of living things showed that no two individuals of any species were exactly alike. He realized that over millions of years, some individuals had traits that gave them an edge to survive and reproduce. As they reproduced,...

Moose, lemmings, owls, wolves, bumblebees, and grizzly bears are some of the many animals that make up a tundra food web. But did you know that worms, beetles, mushrooms, and bacteria break down dead plants and animals into nutrients? Or that tundra animals depend on berries, seeds, and other plants to stay alive? See tundra food webs in action in this fascinating book.

Did you know that both electricity and light move in waves, like water does? What does electricity have to do with magnets? From Benjamin Franklin and Charles de Coulomb to Georg Ohm and James Joule, readers will be introduced to the basic principles of light, electricity, and magnetism in an illuminating way.

Have you ever wondered why things drop to the ground instead of float or fly? Or how a heavy satellite can orbit Earth without crashing into it? From Copernicus and Kepler to Galileo and Newton, the scientific laws that show how and why things move are explored.

Do you know why a 10-ton boat floats but a tiny pebble sinks? Or why a hot air balloon will rise, but when you inflate a balloon it drops to the ground? From Archimedes and Boyle to Pascal and Charles, discover the basic principles of fluid mechanics in a refreshing and fun way.

Have you ever seen a magician make something disappear and question if anything could really just vanish? Do you know why the periodic table is set up the way it is? From Lavoisier and Joule to Dalton and Mendeleyev, take a look at the basic principles of matter and thermodynamics in a fun and exciting way.

This book describes Venus, the second planet from the Sun. The text discusses Venus' distinguishing characteristics, its position in the solar system, its composition and atmospheric conditions, its moons and rings, and how scientists have learned about Venus over time.
