⏱ 0:45 📘 Grade 4 Science · Term 1 · Lesson 5
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.
The videos are narrated in Mandarin Chinese with on-screen subtitles.
📚 What you will learn
A bean seed has a seed coat and an embryo : cotyledons (food store), plumule and radicle. Seeds need water, suitable warmth and air to germinate; light is not needed. Too dry, under water or in the fridge — no sprouting. Change only one condition in a fair test. The radicle grows down into roots, the plumule grows up into stem and leaves.
🎙️ What the video says (in Chinese)
绘本故事《豆豆发芽记》。豆豆：大家好，我是豆豆！我想长成一棵大豆苗！ 豆豆：我穿着一件外衣，叫种皮。剥开种皮，里面是胚：两片胖胖的子叶藏着养料，还有胚芽和胚根。 熊妹妹：豆豆，你发芽需要什么呢？豆豆：需要适量的水、适宜的温度，还有空气！太干不行，泡在水里不行，放进冰箱也不行。 熊妹妹：那要不要晒太阳呢？豆豆：发芽的时候，不晒太阳也可以哦！ 几天以后，胚根先钻出来，向下扎进土里；胚芽向上，长出了茎和叶。 豆苗开花结果，又结出了新的豆豆。植物就是这样用种子繁殖后代的！

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 → 🎬 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!

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: 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 →
