Go with the flow of ocean currents with Bill Nye the Science Guy.

Get ready for “toad-al” fun with Bill Nye and the “Amphibians” episode. Frogs, toads, salamanders, newts, and caecilians (worm-like animals that have backbones) are all amphibians, animals that spend part of their lives in water and part on land. Amphibians are slimy. Amphibians are cold-blooded that means their body temperature changes with the temperature outside.

Ahoy there, matey. Come aboard Captain Nye’s Buoyant Barge of Science.

Bill Nye the Science Guy is no drip – he’s just talking about the water cycle.

Bill Nye the Science Guy is bogged down with information about wetlands.

Bill Nye’s reeling them in with the “Fish” episode.

Everybody in the pool…er pond. It’s the Lakes and Ponds episode.

With the help of Luke Warm, a weatherman on the water channel, two young baseball players come to understand why the big game might be rained out as they are introduced to the key elements that make up and affect the water cycle.

Oceans provide habitats for millions of marine species and cover more than 70 percent of the Earth's surface. Segments detail seafloor maps, the role of water in our planet's life cycles, three states of matter, and the crucial balance among all life-forms.

Is access to clean drinking water a basic human right, or a commodity that should be bought and sold like any other article of commerce? Stephanie Soechtig's debut feature is an unflinching examination of the big business of bottled water.

A huge bottled-water industry has recently emerged, with the U.S. its largest consumer. But is bottled water actually healthier, safer, or tastier than tap water? A water expert explains that bottled water does not meet the same strict standards in the U.S. as water from the tap, though tap-water quality can vary among communities.

Despite its wonders, Earth's water cycle does not spread water evenly around the planet. The Ogallala Aquifer’s huge underground reservoir of water gives the relatively dry Central Plains states such as Nebraska a large but limited irrigation source. But the aquifer's water is being used up faster than it is beng replenished.

Polluted waters can have damaging economic and social effects as well as destroy wildlife habitats. Chesapeake Bay is one of the most polluted bodies of water in America, but local students are working with commercial crab catchers and scientists in the Baltimore area to help restore its health.

The campaign to have water declared a human right was dramatically advanced at the United Nations on July 28, 2010, when a large majority voted for a resolution to recognize the human right to water and sanitation. Canada, the US, and 39 other countries abstained.

More than three decades after the Clean Water Act, two iconic waterways—the great coastal estuaries of Puget Sound and the Chesapeake Bay—are in perilous condition. With polluted runoff still flowing in from industry, agriculture and massive suburban development, scientists fear contamination to the food chain and drinking water for millions of people.
