What this lesson teaches
This activity illustrates the process of evaporation, showing how water changes from liquid to gas. By observing water disappear over time, children learn about molecular movement and states of matter.

This activity illustrates the process of evaporation, showing how water changes from liquid to gas. By observing water disappear over time, children learn about molecular movement and states of matter.
Children engage in a direct observation of evaporation, allowing them to witness scientific concepts in action. This aligns with Vygotsky's scaffolding as they build on prior knowledge of states of matter by seeing real-world examples.
1. Take two shallow dishes and fill one with 200 ml of water. 2. Place both dishes in a warm, sunny spot. 3. Mark the water level in both dishes with a marker. 4. Check the water levels every hour for 4 hours and record your observations. 5. Discuss which dish lost more water and why. 6. Set a timer to check again the next day — what did you notice?
