The learning connection
Engaging in a tangible experiment allows children to visualize and internalize the water cycle concept. The cycle of water changing states aligns with Vygotsky's scaffolding principle, letting kids build upon initial observations to deepen understanding.
Try it with your learner
1. Take a clear glass jar and fill it halfway with water. 2. Cover the top with plastic wrap and secure it with a rubber band. 3. Place a small pebble on the center of the plastic wrap to create a dip. 4. Place the jar in a sunny spot or warm area. 5. After a few hours, observe the water droplets forming on the underside of the plastic wrap. 6. Discuss where the water went and how it returned!
