Water is essential for life. Nothing can survive without it.<\/p>\n

The water that we drink today is the same water that has kept living things alive since living things were created! The water that dinosaurs drank might have been the same water that rained upon the Mayans while they built their great temples, or maybe the same water Columbus sailed upon.<\/span><\/p>\n

The point is that water is very important and we only have a finite supply. We need to take care of that supply.<\/span><\/p>\n

Water Pollution<\/span><\/h2>\n

The biggest threat to our water supply on earth is water pollution. Water pollution occurs when harmful substances are released into water. This can be caused by sewage, industrial waste, or agriculture.<\/span><\/p>\n

Pollution can be intentional or accidental. Factories might knowingly dump their waste products into water supplies to get rid of it. On the other hand, rain water can carry toxic substances from roads, work sites, and gardens into water streams.<\/span><\/p>\n

This polluted water can be harmful to the organisms in the water causing fish and water plants to die. People who drink this water can get sick and possibly die, also. That is why it is so important to both reduce the amount of pollutants that enter our water supply and to remove what pollutants do get into our water.<\/p>\n

Nature\u2019s Water Purification System<\/span><\/h2>\n

In our homes, we might have water filters or buy filtered water. Municipalities have water treatment facilities that clean sewer water before releasing water back into nature. These facilities and filters clean water by removing harmful substances and leaving pure water behind.<\/span><\/p>\n

Nature has it\u2019s own water purification system. It is called the water cycle.<\/strong><\/span><\/p>\n

\"Learning<\/p>\n

Water on the earth in oceans, lakes, streams, and even plants, evaporates and forms water vapor. As the water vapor forms, it leaves minerals and pollutants behind. As the water vapor rises into the atmosphere, it cools and turns back into tiny water droplets. These droplets form clouds.<\/span><\/p>\n

The rain that falls from these clouds is essentially pure and free from pollutants.When the rain falls to earth, it starts the whole water cycle again.<\/span><\/p>\n

Water Cycle Experiment<\/span><\/h2>\n

You can create a small model of the water cycle and see nature\u2019s water purification system in action.<\/span><\/p>\n
