I would like to thank my family for all of their support also I would like to thank all of my teachers for all of the encouragement and most of all I would like to thank god for keeping me calm with all the stress I had.  

The purpose of my project is to explain the processes of the water cycle, explain what it is, and to show the process of evaporation and what happens during this process.my procedure consist of placing the small container in the middle of the large , clear bowl. Fill the bowl with a little water, being careful not to fill the small container inside. Cover the bowl with plastic wrap, and fasten the plastic wrap around the rim of the bowl with your rubber band or string. Put a weight on top of the plastic wrap in the center. Now put your contraption on a windowsill or somewhere that the sun will hit it.The heat of the sun evaporated which raised, condensed on the cool plastic, and fell into the small container. This small scale replica of the water cycle that occurs every day on earth. I learned that the water cycle is also called the hydrologic cycle and that many process of the water cycle go on in my household everyday which helps me better understand the water cycle. If I did this project again I probably would test and see if the water evaporates faster under sun light or light from a light bulb faster.  

The Water Cycle
Hello! My name is Kameron Boler and my project is about the water cycle. I had a lot of trouble coming up with an idea for my science fair project all I knew was I wanted to do something involved with chemistry so I chose to construct a mentosMentos soda volcanoe . volcano. So I built my volcanoevolcano with the home made plaster I made and after a few days my volcanoevolcano broke and when I went on the internet to get more info on my project I found out I was doing my project all wrong. After calming down I decided to do my project on one of my favorite science topics the “water cycle”. . The water cycle, also known as the hydrologic cycle or the H2O cycle, describes the continuous movement of water on, above and below the surface of the Earth. The mass water on Earth remains fairly constant over time but the partitioning of the water into the major reservoirs of ice, fresh water, saline water and atmospheric water is variable depending on a wide range of climatic variables. The water moves from one reservoir to another, such as from river to ocean, or from the ocean to the atmosphere, by the physical processes of evaporation, condensation, precipitation, infiltration, runoff, and subsurface flow. In so doing, the water goes through different phases: liquid, solid, and gas .gas. The water cycle involves the exchange of energy, which leads to temperature changes. For instance, when water evaporates, it takes up energy from its surroundings and cools the environment. When it condenses, it releases energy and warms the environment. These heat exchanges influence climate. The evaporative phase of the cycle purifies water which then replenishes the land with freshwater. The flow of liquid water and ice transports minerals across the globe. It is also involved in reshaping the geological features of the Earth, through processes including erosion and sedimentation. The water cycle is also essential for the maintenance of most life and ecosystems on the planet.

The Sun, which drives the water cycle, heats water in oceans and seas. Water evaporates as water vapourvapor into the air. Ice and snow can sublimate directly into water vapourvapor. Evapotranspiration is water transpired from plants and evaporated from the soil. Rising air currents take the vapourvapor up into the atmosphere where cooler temperatures cause it to condense into clouds. Air currents move water vapourvapor around the globe,globe; cloud particles collide, grow, and fall out of the upper atmospheric layers as precipitation. Some precipitation falls as snow or hail, sleet, and can...
