In Double Decker Buses Mean Double the Fun!, presenter and motorbike racer Grace Webb explores the features of a double decker bus and even tries her hand at driving some passengers around on the track. This video is excerpted from BBC’s Grace’s Amazing Machines, a children’s show that introduces kids to some of the biggest, fastest, and most amazing machines in the world.
In A Trap in Bloom: The Venus Flytrap’s Double Life, narrator Sir David Attenborough introduces the Venus flytrap, a carnivorous plant that attracts insects with sweet nectar on its leaves. When an insect triggers the hairs on the trap, it snaps shut. After a few days it reopens, leaving only the insect’s dry remains. However, Venus flytraps also need to pollinate, so it grows tall flowers away from its traps, allowing insects to safely feed on nectar and spread pollen, ensuring the plant can reproduce. This video is excerpted from BBC's Life, a show that explores the remarkable strategies animals and plants use to ensure their survival.

Rhinos are among the oldest groups of mammals on Earth, with ancestors that roamed the planet millions of years before humans. Today, however, these iconic animals are among the world's most endangered species.
In this fact file video from Chester Zoo, discover the remarkable adaptations of the eastern black rhinoceros, from its iconic double horns and swiveling ears to its unique prehensile lip that helps it feed on leaves and branches. Learn how these solitary giants communicate, care for their calves, and survive in the grasslands and savannas of eastern Africa, while exploring the conservation efforts working to protect this critically endangered species from extinction.
In Thomas Jefferson Takes Power, learn how Thomas Jefferson became the first president inaugurated in Washington, D.C., and promoted freedom of religion and the separation of church and state. He significantly reduced the national debt, reformed taxes, and faced early foreign challenges, including confrontations with Barbary pirates. Jefferson also oversaw the Louisiana Purchase, doubling the size of the United States, and commissioned exploration of the Mississippi River.
In Life Beneath the Antarctic Ice, learn how the world's largest desert doubles in size during winter, creating a vast, frozen expanse. Beneath the ice lies a surprisingly stable environment, allowing life to evolve and thrive in extraordinary ways. This video is excerpted from BBC’s Seven Worlds, One Planet, a series featuring remarkable animal behavior from all seven continents.
In The Red Knot Bird's Essential Pit Stop, narrator Sir David Attenborough follows red knot birds on their nearly 10,000 mile (16,000 kilometer) journey from Argentina to Canada. They stop in Delaware Bay to feast on horseshoe crab eggs, needing to eat up to 400,000 eggs to double their weight before continuing their journey. But all that feeding makes them easy targets for predators like the peregrine falcon, adding danger to their incredible adventure! This video is excerpted from BBC's Life, a show that explores the remarkable strategies animals and plants use to ensure their survival.
In Polar Bears in Winter, narrator Sir David Attenborough highlights a polar bear waiting through the Arctic winter with little food and in harsh conditions. Nearby, polar bear cubs are born tiny and blind. The polar bear cubs spend the winter cuddled with their mother where they drink milk so rich they can double their weight every few weeks. This video is excerpted from BBC’s Frozen Planet, a series that shows a fragile world of beauty and hostility, where nature finds a way to survive and thrive in frigid conditions.
