The document describes the water cycle and the process of evaporation. It then provides instructions for an experiment using a solar still to clean dirty water. Water is poured into a plastic bowl along with dirt and food coloring to simulate dirty water. The bowl is covered with plastic wrap with a glass under it to collect the condensation. In sunlight, evaporation occurs and the water vapor condenses on the plastic wrap above the glass, leaving the dirt behind to produce clean water samples. The experiment demonstrates how nature can be used to clean water through evaporation and condensation in the water cycle.

- 1. CLEANING WATER Jordy Arellano Jorge Flores Ricardo Romero Mateo Sarsoza
- 2. Water Cycle It describes the continuous movement of water on, above and below the surface of the Earth.
- 3. Steps of the water cycle Precipitation Snowmelt Runoff Infiltration Subsurface flow Evaporation Sublimation Deposition Condensation Transpiration Percolation
- 5. Evaporation It is the process process by which water changes from a liquid to a gas.
- 6. Cleaning Water Through a Solar Still (Evaporation) A solar still is a low-tech way of distilling water, powered by the heat of the sun.
- 7. Explanation
- 9. MATERIALS Large plastic bowl Water Dust and soil Dark food coloring Small, heavy, drinking glass Clear plastic wrap Tape A Pebble
- 11. PROCEDURE I. Pour Water into the bowl until it is about 3cm deep II. Mix dust and soil into the water, add a few drops of food coloring
- 12. PROCEDURE III. Place the clean, dry glass right side up in the center of the bowl
- 13. PROCEDURE IV. Cover the bowl loosely with plastic wrap. Tape the edges of the plastic wrap to the bowl.
- 14. PROCEDUREV. Place the pebble on the plastic wrap directly over the glass. The pebble should push the plastic down a bit. The plastic must not touch te glass
- 15. PROCEDURE VI. Leave the in full sunlight for a few hours
- 16. PROCEDURE VII. Observe the changes
- 18. CONCLUSIONS The principal benefit that this process provides us, is that water can be cleaned with the help of nature. The resulting water needs to go through another process to be completely clean. This experiment determines a viable solution to the problem that now affects the whole planet.
- 19. CONCLUSIONS This experiment is not the only way to use the sun's energy to transform dirty water into clean water. The water cycle is an interesting process that happens every day, everywhere. This whole process can be recreated with a simple experiment using only water, a bowl and plastic wrap.
