This project allows students to visualize the water cycle using a simple bag experiment. By observing evaporation and condensation, they understand the cycle's importance in nature.
If I create a closed environment with water in a bag, then I will observe evaporation and condensation, demonstrating the water cycle.

Fill the Ziplock bag with water and seal it tightly.
Draw the sun and clouds on the bag with permanent markers.
Tape the bag to a sunny window, ensuring it is vertical.
Observe the bag over several days.
Note any condensation and water drops inside the bag.
Record your observations daily.
Discuss how evaporation and condensation occur in the water cycle.
Present your findings at the science fair.
You should see water evaporating and condensing inside the bag, demonstrating the water cycle. This visual representation will help solidify your understanding of this vital process.
Amount of sunlight exposure
Amount of condensation observed

Ensure not to overfill the bag to prevent leaks. Handle markers with care to avoid staining.
Create a poster explaining the water cycle.
Use your bag experiment as a live demonstration.
Share fun facts about the water cycle.
Discuss the importance of the water cycle to ecosystems.
You should start to see results within a few days of placing it in the sun.
It helps to visualize the components of the water cycle, making it more engaging.
Yes, but clear bags work best to see the water cycle clearly.
