On a special field trip in the magic school bus, Ms Frizzle's class learns at first hand about different kinds of rocks and the formation of the earth.

Shubin shows how the entirety of the universe's fourteen-billion-year history can be seen in our bodies as he moves from our very molecular composition (a result of stellar events at the origin of our solar system) through the workings of our eyes.

"As new groundbreaking research suggests that climate change played a major role in the most extreme catastrophes in the planet's history, award-winning science journalist Peter Brannen takes us on a wild ride through the planet's five mass extinctions and, in the process, offers us a glimpse of our increasingly dangerous future."--

In January 2004, two NASA rovers, Spirit and Opportunity, landed on Mars and began to explore the planet's surface. Their mission: to probe the exotic Martian geology for signs of water, past or present. In this science bulletin, scientists at NASA explain the goals and challenges of the current Mars mission, and how evidence of water could bolster the possibility that life may once have existed on Mars.

This program will explore the composition of Earth, including the characteristics of the Earth’s surface, life on Earth, and the planet's many kinds of plants, animals, and fish.

In summer, Yellowstone Park's dry forests burn for miles. The sky is dyed scarlet, the sun snuffed out by clouds of black smoke. But, in fact, these fires are responsible for sustaining the forest in the long run.

Volcanoes and life regulate the earth's atmosphere in an intricate and finely balanced interplay.

The world's deserts are lands of extremes that force animals to come up with ingenious ways of coping with hostile conditions, giving rise to the most incredible survival stories on Earth. A pride of desert lions are so hungry they risk hunting a giraffe several times their size, while male sandgrouse fly 120 miles each day to the nearest waterhole and dice with death to collect water for their chicks. Filmed for the first time, a tiny bat does battle...
