A compass has a case , a dial and a magnetic needle — the needle is a tiny magnet. However you turn the compass, the red tip points north .

🎙️ What the video says (in Chinese)
阴雨天看不见太阳，怎样辨认方向？我们可以用指南针！ 指南针有外壳、方位盘和磁针；磁针是一块小磁铁。 不管怎么转，红色针尖总是指向北方。 平放，转底盘让北对齐红色针尖，就能读方向。 用磁铁沿同一方向摩擦针二十多次，浮在水上就成了指南针！ 记住：指南针是我国古代的伟大发明！

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.

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 → 🎬 Compass Lab 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. 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 →
