Annotation:Featuring stunning photographs, beautiful illustrations, and detailed text, Rainforest Food Chains examines the delicate balance of life maintained in lush Southeast Asian tropical rain forests. Children will learn how the plants and animals in a rain forest rely on one another to survive.

Annotation:Provides an overview of the rain forests of the world and describes the rain forests of the Pacific Northwest and the life that they support.

Annotation:Learn how geology and physical geography are intertwined and explore the wonders of the Pacific Northwest. Washington, Oregon, Idaho, Alaska, western Montana, and northern California are a unique part of the United States known for its explosive volcanoes and earthquakes. The region has everything from glaciers and tundra to mighty rivers and the only temperate rainforest in the United States.

Annotation:Forests are biomes in which trees are the main life form, but what makes a forest deciduous? Students will explore these colorful woodlands that change with the seasons.

Annotation:Deserts cover nearly one-fifth of the Earth's land surface. Even in these sand-filled expanses that dot the globe, much life can be found, from plants like cacti and sagebrush to well-adapted animals such as the Gila monster and the sidewinder. Discover how the process of desertification continually changes more land into deserts each and every year.

Annotation:Students will examine the importance of grassland regions and participate in a hands-on experiment to measure the moisture content of soil. An ecologist also discusses how scientists are restoring grassland regions to their original state.

Annotation:Illustrated guide to the plants, animals, and insects found in the world's tropical rain forests.

Annotation:Describes the climate, seasons, plants, animals, and soil of the boreal forest, a biome or land zone, which stretches across the northern parts of North America, Europe, and Asia.

Annotation:Takes readers on a walk through a tropical rain forest, showing examples of how the animals and plants depend on each other and their environment to survive.

Annotation:Examines countless wonders of prairie grasslands.

Annotation:In Marine ecosystems, students will explore saltwater environments -- from shorelines to coral reefs -- and learn about the fish, plants, mammals, and insects that depend on each other for survival in this aquatic biome. Examine concepts such as salinity and currents, and find out about the three major life zones found in ocean waters. A fun, hands-on experiment allows students to discover how brine shrimp have adapted to changes in salt concentration, while a visit with a marine biologist on the Chesapeake Bay examines the fascinating life cycle of the blue crab.

Annotation:Mazes through 12 ecosystems, from evergreen forests to coral reefs, from the frozen tundra to hot desert sands.

Annotation:Students will discover how the species of the rainforest have adapted to the temperature and humidity, and why the threat of its destruction will have a far-reaching impact on our planet. A visit with an ecologist at the Caribbean National Forest in Puerto Rico examines the work underway to restore the population of the endangered Puerto Rican parrot, while a hands-on investigation demonstrates the vital role that rainforests play in recycling water.

Annotation:An introduction to deserts and how life survives in them.

Annotation:Students get a close-up look at the fragile biome that covers 20% of the world's surface from the polar regions to the mountaintops of Europe and North America. Students can also participate in an experiment that demonstrates why tundra plants are dark in color.
