This activity helps students identify physical and chemical properties of different materials. By observing changes and reactions, children learn the distinction between mixtures and pure substances.
Engaging with familiar materials allows students to actively classify them based on observable traits. By using embodied cognition, they connect tactile experiences with scientific concepts, aiding retention of complex terms like 'solution' and 'compound'.
1. Gather 5 materials: salt, sugar, sand, water, and oil. 2. Place each material in separate clear cups. 3. Add 100 ml of water to each cup with solid materials. 4. Stir and observe — what dissolves? What stays? Record your observations. 5. Mix oil with water in a new cup and note the result. Does it mix or separate? 6. Discuss with your partner: Which materials are pure? Which are mixtures?
