Dissolving for Kids | Where Did the Sugar Go? 🥄 | The Dropples S1 E10

Dissolving for kids: where did the sugar go? Drip stirs one spoon of sugar into a cup of water... and it's gone! Or is it? 🥄 Meet Drip the water drop, Puff, and Frost the ice cube, and play "Can we see it?" Sugar, sand, a pebble, salt and glitter all go into water. Is it too tiny to see, or can we see it? Guess, watch, and shout the answer with them! Then Frost gets a little worried that he is dissolving. (He is only melting.) 🖌️ Try it at home with a grown-up: two plastic cups of cool water. Stir a small spoon of sugar into one and a small spoon of sand into the other. Count your stirs and watch. It's for looking only, so we don't drink it! 🧪 Safety (for grown-ups): this is a looking experiment. Nobody tastes or drinks it, and a grown-up helps with every pour, sprinkle and stir. Use cool tap water (no hot water) and plastic cups. Keep pebbles and glitter for the grown-up only: small items are not for mouths. Pour sandy water on the garden, not down the sink. ⏱️ Chapters 0:00 Drip's sugar disappears? 0:14 Puff's pretend super-zoom 0:42 Round 1 · Sugar 1:17 Round 2 · Sand 1:43 Round 3 · A pebble 2:08 Frost the ice cube 2:20 Round 4 · Salt 2:56 Round 5 · Glitter 3:30 The salt comes back 3:56 Try it at home 4:19 See you next time 👪 For grown-ups This episode is about dissolving. When sugar or salt dissolves in water, the water pulls it apart into bits too tiny to see, and they spread all through the water. The sugar is not gone; it is still there. Water doesn't pull the sand, the pebble or the glitter in our cups apart, so we can still see them. Stirring only makes dissolving faster. Frost the ice cube is not dissolving: he is melting because he is warm. The "super-zoom" in the episode is pretend: dissolved bits are much too small to see, even with a magnifier. The salt proof (salty water drying on a dark plate leaves a white ring) is a way to find out without tasting. We use salt, not sugar, for this proof because the white salt ring is easy to see. Questions to ask after watching: Where did the sugar go? Which things could we still see? How do we know the salt is still there? 📚 Science sources (for grown-ups) • Sugar dissolves into tiny bits, still in the water: University of Wisconsin-Extension 4-H, Solubility & Density — https://4h.extension.wisc.edu/files/2... • Sugar and water, "still in the water": Stanford University, Mixing Sugar and Water — http://scientificargumentation.stanfo... • Stirring dissolves sugar faster; sand vs sugar: Hofstra University, Solubility Unit teacher guide — https://www.hofstra.edu/pdf/academics... • Sugar and salt are left behind when water dries: University of Illinois Physics Van, Does Sugar Evaporate? — https://van.physics.illinois.edu/ask/... • Salt crystals form when salty water evaporates: Earthlearningidea, Salt of the Earth — https://www.earthlearningidea.com/PDF... • Most glitter is plastic (that it stays in pieces in a cup of water is our own reasoning, not a quote): Anglia Ruskin University study via Cambridge Network — https://www.cambridgenetwork.co.uk/ne... • Ice melts above 0 °C (Frost melts, he doesn't dissolve): University of Illinois Physics Van, Temperature of Ice — https://van.physics.illinois.edu/ask/... #ScienceForKids #Dissolving #TheDropples
