In The Formation of Stalactites and Stalagmites, narrator Sir David Attenborough explains the fascinating process of how stalactites and stalagmites form in caves, focusing on the Bornean caves. Rainwater eats away at limestone, leading to the formation of these unique cave structures. Water loaded with dissolved limestone deposits calcite to create stalactites from the ceiling and stalagmites from the floor. This video is excerpted from BBC’s Planet Earth, a breathtaking documentary series that highlights the natural wonders of our planet.
In Clean Streets Ahead! How Road Sweepers Tackle Dirt, presenter and motorbike racer Grace Webb investigates the outside and inside of a road sweeper, a vehicle with three big brushes that sweep dirt off the road. Road sweepers spray powerful water through nozzles to wash away stubborn grime, and for tough dirt, there's a giant vacuum in the back that collects everything into a compartment called the hopper! 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 Tree Planters for a Greener Future, presenter and motorbike racer Grace Webb explores machines dedicated to reforesting areas where trees have been cut down. In a sustainable forest, she learns how these machines are loaded with saplings, which they plant and water to help regrow the forest. 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 How Earth Got Its Water, geologist Iain Stewart explains how Earth's first oceans were born from a rainstorm that lasted hundreds of thousands of years. But that epic downpour only gave Earth half its water — the rest came from space! Scientists crashed a satellite into a comet to uncover how these icy space rocks helped fill our oceans billions of years ago. And the story isn’t over — today, in East Africa, a massive crack is slowly splitting the continent, and one day, it could form a brand-new ocean! This video is excerpted from BBC’s Earth: The Power of the Planet, a documentary series in which Dr. Iain Stewart discovers how Earth's forces can shape nature, species, and even the climate.
In The Fin Garden of Kashan, host Joanna Lumley visits a garden that was built in 1590 by channeling an ancient spring to bring flowing water to the desert. The water in this garden flows even during times of drought. The technology used to bring water to the surface has since been used in many other parts of the world. This video is excerpted from BBC’s Joanna Lumley’s Silk Road Adventure, a documentary series uncovering the rich history and cultural treasures of the Silk Road.
In Caring for Our Donkey Pals!, host Rory Crawford visits a lively donkey sanctuary where she meets William D, a lovable male donkey, also known as a jack. Donkeys are social creatures that love to hang out with their friends and make a silly sound called a bray — imagine a big "hee-haw"! These strong animals can carry heavy loads, but they need special care too, such as brushing their soft coats, cleaning their hooves, and providing yummy straw, grass, and fresh water. This video is excerpted from BBC’s My Pet and Me, a children’s show that introduces kids to the rewards and responsibilities involved when having a pet.
