Picture Book: Where Did the Salt Go?
⏱ 0:42 📘 Grade 2 Science · Term 1 · Lesson 5
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!
The videos are narrated in Mandarin Chinese with on-screen subtitles.
📚 What you will learn
Sugar and salt get smaller and disappear in water: they dissolve . Sand sinks and oil floats: they do not dissolve . Dissolved salt is still there; when the water dries up, the salt appears again.
🎙️ What the video says (in Chinese)
绘本故事《盐去哪儿了》。小兔在煮蔬菜汤,往锅里放了一勺盐。小兔:咦?盐怎么不见了? 猫博士:我们来做个实验!把白砂糖、食盐、沙子和食用油,分别放进水里,搅一搅。 猫博士:糖和盐在水里越变越小,最后看不见了,这叫溶解。小兔:沙子沉到了杯底,油浮在水面上,它们不能溶解! 小兔:那溶解了的盐,还能找回来吗?猫博士:把盐水放在太阳下面,水慢慢地跑走了……小兔:哇,杯底出现了白白的盐! 原来,盐没有消失,它溶解在了水里。小兔的汤,咸咸的,真好喝!

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: 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.
