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.
The videos are narrated in Mandarin Chinese with on-screen subtitles.
📚 What you will learn
Air has no colour, smell or taste ; you can’t see or touch it. Push a bag of air into water and poke it: bubbles come out. Air flows and has no fixed shape ; moving air is wind. We need air to breathe; fire needs air; tyres are filled with air. Keep air clean!
🎙️ What the video says (in Chinese)
绘本故事《看不见的朋友》。熊妹妹捡到一个鼓鼓的塑料袋。熊妹妹：咦，袋子里什么也没有呀？ 空气宝宝：嘻嘻，我就在袋子里！我是空气宝宝！熊妹妹：可我怎么看不见你？空气宝宝：我没有颜色，没有气味，也没有味道。你看不见我，也摸不着我。 熊妹妹：那我怎么知道，你在袋子里呢？空气宝宝：把袋子压进水里，戳一个小洞看看！咕噜咕噜，水里冒出了一串泡泡！ 空气宝宝：我会流动，没有固定的形状。吹进气球里，我就是圆圆的。我跑起来，就变成了风，能让风筝飞上天！ 空气宝宝：你呼吸要靠我，东西燃烧要靠我，轮胎里也装着我。熊妹妹：原来空气这么重要！ 空气宝宝：请保护好我，别让烟和垃圾把我弄脏哦！空气看不见、摸不着，可它一直在我们身边。

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.

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 → 🎬 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 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 →
