Hypothesis 
Water inside the environment will rise up into the air as a vapor, and as it cools, tiny water droplets which simulate clouds will form and fall back to the soil simulating the rain that falls to the earth, flowing into rivers, lakes, and oceans. The cycle will continue.
 
Abstract 
 This project attempts to create an environment which demonstrates the two processes of the water cycle, evaporation and condensation as they naturally occur on earth. 
 
Materials   
     1.  glass environment container 
     2.  2 small greenplants 
     3.  small baby food jar of water 
     4.  Soil 
     5.  Sand 
     6.  Small rocks 
     7.  Plastic wrap 
       
Procedure   
  1. Layer bottom of container with 2 inches of small rocks.
  2. Next layer 2-3 inches of sand on top of the rocks. 
  3. Now add about 4 inches of soil on top of the  
  4. Put green plants on one side of container and water. 
  5. Bury the baby food jar with water into the soil so that only  the rim can be seen. 
  6. On the next day, put plastic wrapping over plants and place in a sunny place. 
  7. Observe to see how the water cycle works. 
Results   
The next day, we observed droplets of water on the leaves of the plants, and also, droplets of water  completely covered the glass on the inside of the environment where it had been completely dry on the day we first prepared our environment.
Conclusion 
Some of the water from our environment's "lake" evaporated. This means that some of the lake water turned to water vapor and rose upward in the glass environment. As the water rose in the environment, it cooled and  condensed. This means that the water vapor took another form and became water droplets. Condensation is what covered our plants and the glass sides of the environment. As long as the environment remains covered with& plastic, and water remains in our lake, we expect to see the processes of evaporation and condensation demonstrated inside the environment.

Water never disappears. Even after it falls to the earth onto the ground or is absorbed into rivers and lakes and oceans, the sun causes it to evaporate. into the atmosphere where it cools and forms clouds. Then it falls back to earth in the form of rain, snow, hail or fog.The cycle will continue.
