This activity teaches students about solubility and how certain substances dissolve in liquids. By observing the sugar disappear, children grasp the concept of solutions and learn that mixing can create new properties.
Experiencing the dissolution firsthand supports embodied cognition, where children visualize and physically observe the process of solubility, making the abstract concept more relatable and memorable.
1. Gather 2 clear glasses and fill them with 200 ml of water each. 2. Add 2 tablespoons of sugar to the first glass and stir with a spoon. 3. Observe how the sugar disappears in the water. 4. In the second glass, add 2 tablespoons of salt instead and stir. 5. Compare how fast the sugar and salt dissolve — which one disappears first? 6. Discuss with your partner why the two substances behave differently in water.
