Transcript of Water Conservation
What patterns may occur because of the low amount of fresh water?
Ways to Conserve Water
What water is being used for?
What are the Details of Earth's Fresh Water?
Mr. Lindquist Class
70% of Earth's surface is covered in water
3% of Earth's water is fresh water
7/10 of Earth's fresh water is frozen in glaciers
An average American uses 140-170 gallons of water per day
A human body is made up of 75% of water (1)
Take shorter showers.
Turn off the water when you are brushing your teeth.
Water grass and plants less often.
Fill up a bucket with water while you are waiting for the sink temperature to warm up or cool down. (2)
Did You Know?
An average five-minute shower takes fifteen to twenty gallons of water. Around forty gallons of water are used in ten minutes of a shower. (2)
Did You Know?
Watering plants less often builds stronger and healthier roots. (2)
Did You Know?
When you turn off the water when you are brushing your teeth you can save 5 gallons of water. (2)
Did You Know?
With that extra water that you saved in your bucket, you can water the plants with it. (2)
Water is never used up
Water is reused and remade in a process called the water cycle
Perhaps the water that Alexander the Great drank was the water you took a shower in. (3)

The Water Cycle
Heat from the sun evaporates the ocean water
The water rises as vapor to the sky to form clouds
Then the vapor eventually get heavy enough to drop to the ground as some moister. (4)
industrial uses 22%
household uses 8% (3)
Precipitation mostly falls as rain, hail, snow, sleet, and freezing rain.
The most common kind of precipitation is rain which is a drop of water.
Most precipitation falls back into the ocean. (5)
What are the rules to making fresh water?
Water is a natural state seldom that is free of bacteria, sparkling clear, and without taste or odor.
Most cities use three basic processes: 1. coagulation and settling 2. filtration 3. disinfection (3)
Coagulation and Settling
Raw water flows through the treatment plant and is mixed with chemicals called Coagulants.
The most widely used coagulant is called aluminum sulfate or alum. The alum forms sticky globs called flocs which impurities attach to.
Then the water passes through a settling basin where the flocs settle to the bottom. (6)
Water is then passed through a filter.
While the water flows through the filter and the remaining particles are removed. (6)
It kills disease-carrying bacteria.
Treatment plants disinfect water by adding a substance called chlorine.
Chlorine removes bacteria and viruses. Enough chlorine is added to the water filtration system so that when the water leaves the plant some chlorine stays to protect the public (6)
