This activity demonstrates evaporation, condensation, and precipitation in a simple visual model. Children see how water transforms between states, making the water cycle concept tangible and relatable.
Using a clear resealable bag allows children to observe the water cycle in real-time, solidifying their understanding through embodied cognition. When they see water droplets forming and 'raining' back into the bag, they actively connect abstract concepts with observable phenomena.
1. Gather a resealable plastic bag and a permanent marker. 2. Fill the bag with 1/4 cup of water. 3. Seal the bag tightly and tape it to a sunny window. 4. Observe the bag over a few hours — what happens to the water? 5. Draw what you see on the outside of the bag — label evaporation, condensation, and precipitation. 6. Discuss with your family how this relates to the larger water cycle.
