Dr Cat and Bunny make a compass in the lab: gather the materials, guess what will happen (3-2-1!), rub a needle with a magnet, test it on paper clips, float it on water — and it points north and south.
The videos are narrated in Mandarin Chinese with on-screen subtitles.
📚 What you will learn
Materials: a sewing needle , a magnet , a piece of foam and a bowl of water . Guess first, then test: does the needle become a magnet? Rub the needle with one end of the magnet 20+ times in one direction — careful with the sharp tip! The magnetised needle picks up paper clips; floating on foam it turns and points north–south .
🎙️ What the video says (in Chinese)
小兔：阴天没有太阳，我们怎么认方向呀？猫博士：欢迎来到小实验室！我们自己做一个指南针！ 猫博士：准备材料：一根缝衣针、一块磁铁、一小块泡沫，还有一碗水。 猫博士：先来猜一猜：针在磁铁上摩擦以后，会变成什么呢？（3、2、1，想一想）小兔：我猜，它也会变成一块小磁铁！ 猫博士：开始实验！用磁铁的一端，沿着同一个方向，摩擦二十多次。小兔：小心针尖，别扎到手！ 猫博士：现在，拿针去碰一碰回形针。小兔：哇，吸起来了！我猜对啦！猫博士：针被磁化，变成了一根小磁针。 猫博士：把针放在泡沫上，轻轻放进水里。小兔：它转呀转，停下来，指着南北方向！ 猫博士：实验结论：磁化的针能指南北，这就是一个指南针！一起说：实验成功！

🎬 Why Can Some Fish Be Caught? The rod has a magnet on the end and the catchable fish hide paper clips: magnets attract iron. A magnet even pulls a paper clip out of a glass of water. Watch → 🎬 Our Five Senses Eyes see colour and shape, ears hear sounds, the nose smells, the tongue tastes and the hands feel hard or soft. Never taste things you don’t know! Watch → 🎬 Five-Sense Detective: The Mystery Bag Detective Bear and Little Bear solve the mystery bag with five clues: look, touch, smell, listen and taste. Red, round and smooth, sweet-smelling, a dull knock, sweet and crunchy — it’s an apple! Watch → 🎬 Same and Different: How to Sort Sort a basket of fruit and vegetables by colour, then by shape. A different rule gives different groups, so first look for what things have in common. Watch → 🎬 Picture Book: Little Bear Tidies Up A picture-book story: Big Bear helps Little Bear sort her toys — first by colour, then by shape, then by size. The same toys sort differently because the rule is different. Watch → 🎬 Cats and Rabbits A kitten and a bunny compare their skills. Rabbits have long ears, hop and love grass and carrots. Cats climb trees and their pupils grow big at night. Both have fur and four legs, eat and grow. Watch → 🎬 What Are Things Made Of? Wooden chairs, metal spoons, glass cups and cloth shirts. Glass is clear but breaks; metal is strong and shiny; pan handles use wood or plastic because metal gets hot. Watch → 🎬 Materials Talent Show Wood, metal, glass and plastic take the stage to show off: wood is strong and warm, metal shiny and tough, glass clear but breakable, plastic light and colourful. Final challenge: who makes a pan handle? Watch → 🎬 All Kinds of Leaves A leaf has a blade and a stalk. Maple leaves look like a hand, pine leaves like needles, lotus leaves like a plate. A magnifier shows the veins. Watch → 🎬 Picture Book: Little Ant Crosses the River A picture-book story: Little Ant needs a boat made of a leaf. A pine needle is too thin, a maple leaf spins in the water, but a big round lotus leaf works — with its blade to sit on, a stalk to steer and veins on top. Watch → 🎬 Colourful Flowers Flowers have petals and a centre with stamens. Their colours, shapes and sizes differ, but most have petals and stamens. Smell flowers by wafting, and never taste unknown plants. Watch → 🎬 Picture Book: Little Bee Looks for Nectar A picture-book story: Little Bee visits pink, yellow and purple flowers. They differ in colour, shape and size, but all have petals and stamens. Bee teaches Little Bear to waft a flower’s scent and never taste unknown plants. Watch → 🎬 Find Directions with the Sun Little Bear and Big Bear work it out together: the sun rises in the east and sets in the west. Face the sun in the morning: east ahead, west behind, north on the left, south on the right. Maps put north at the top. Watch → 🎬 The Secret of Magnet Poles A bar magnet holds the most paper clips at its two ends — the poles, N and S. Like poles push apart, unlike poles pull together, which is how a magnet can push a toy car without touching it. Watch → 🎬 Meet N and S (Cartoon) Little N and Little S, the two ends of a magnet, tell their own story: they hold the most paper clips, two Ns push each other away, N and S hug tight, and when hung up N points north. Watch → 🎬 Make a Compass A compass has a case, a dial and a magnetic needle whose red tip always points north. Turn the dial so north lines up with the red tip. Rub a sewing needle with a magnet and float it on water to make your own. Watch → 🎬 Picture Book: Two Little Flowers Big Bear keeps his flower on the sunny balcony and waters it; Little Bear forgets hers in a dark cupboard. A week later one blooms and one wilts — plants need water, sunlight and air. Watch → 🎬 Picture Book: Where Did the Salt Go? Bunny’s salt vanishes in the soup. Dr Cat tests sugar, salt, sand and oil in water: sugar and salt dissolve, sand sinks, oil floats. Leave salty water in the sun and the salt comes back! Watch → 🎬 Picture Book: The Invisible Friend Little Bear finds a puffy bag — and Air Baby pops out! You can’t see, smell or taste air, but bubbles prove it’s there. Air flows, has no fixed shape, makes wind, and we breathe it. Watch → 🎬 Picture Book: The Bears Move House Big Bear pulls and Little Bear pushes the heavy box. Pulling is towards you, pushing is away. Pushes and pulls move things and change their shape; a cart makes it easier, and rowing uses both. Watch → 🎬 Picture Book: Little Ant Builds a Boat Little Ant draws a design (bow, stern, deck, cabin, mast, sail), builds the boat from foam, a straw and paper, then tests it: it tips over, so she shortens the mast; it leaks, so she waterproofs the cabin. Success! Watch → 🎬 Picture Book: Is a Bat a Bird? Little Bat flies to the birds’ party, but has no feathers or beak. At the mammals’ party it fits right in — fur, and babies fed on milk. Whales are mammals too, not fish. Watch → 🎬 Picture Book: Bean Sprouts Bean shows its seed coat and embryo (cotyledons, plumule, radicle). It needs water, warmth and air to sprout — not sunlight. The root goes down, the shoot grows up, and new beans grow. Watch → 🎬 Picture Book: The Dented Ping-Pong Ball Little Bear’s dented ping-pong ball pops back out in hot water: the air inside expands. Water expands too — that’s how thermometers work. Rails have gaps, sky lanterns rise, and ice is the exception. Watch → 🎬 Picture Book: Little Drop’s Journey Little Drop lives in the ocean (71% of Earth’s surface), evaporates into vapour, condenses into clouds and rain, freezes at 0 °C and boils at 100 °C. Fresh water is scarce — save water! Watch → 🎬 Picture Book: The Singing Rubber Band Dr Cat shows Bunny that sound comes from vibration, travels through air, water and solids (but not a vacuum), is louder with bigger vibrations and higher with faster ones. Bunny makes a straw panpipe! Watch →
