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.

Did somebody say CAT scan? The Norfolk Zoo is doubling down on the idea of a big CAT scan by giving a big cat a scan! A tiger named Mishka is one of many animal patients that the zoo is sending through a CAT, or CT, scan. Short for “computerized axial tomography” or “computed tomography,” depending on how much time you have and how much you want to impress your friends, CT scans use a combination of X-rays and computer technology to help see inside bodies, produced detailed images of bones, organs, and soft tissue.
To the untrained eye, the scan’s grey and white blobs may look like, well, blobs. But, skilled professionals will be able to see if they show any abnormalities in bones or soft tissues. In addition to Mishka, the zoo also checked out other animals like a vulture, penguin, and sloth.
Their scans will not only help animals at the zoo, but in the wild, too. The findings will be added to the base knowledge on a species or animal, which can be shared with experts and vet colleagues globally.
To reach the golden double six, it will take some special tricks! You'll need to build the paths and so, go, go, domino! Cut out the dominoes and pick the right ones to finish building the paths. Where will you put the golden double six?

Let’s catch the bus to... the museum. (But only because you’re secretly in love with the bus driver!) Here's how to play:
- Try to get around the board without the grannies causing too much chaos!
- Grab a counter* (or two, if you’re playing with a friend) and place it on the start. *A button or small toy work well!
- Take turns rolling a die and moving the number of steps you roll. Be prepared for granny stops! The first one to the end wins.
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.

Jefferson also oversaw the Louisiana Purchase, doubling the size of the United States, and commissioned exploration of the Mississippi River.
Get ready for a speedy adventure! This BBC Learning Hub playlist, packed with clips from Grace’s Amazing Machines, takes students on a high-octane journey through land, sea, and sky. From gyrocopters and tugboats to superbikes and supercars, each video introduces a powerful machine — and the science that makes it move.
Perfect for teaching concepts like forces and motion, energy, friction, and transportation technology, these clips are a fun, fast-paced way to explore how things go, glide, float, and fly. Each video comes with discussion questions, hands-on activities, and more to help kids think, tinker, and learn like real engineers. Buckle up — it’s going to be a wild ride!
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.
