This course is Water or H2O, the project is making a a power point about a city we had to choose. The thing that I did really well is making the power point and finding the research. Something that is did wrong was looking at the wrong places for my research. Something I am proud of this my whole power point.

Water Filter

This course is Water or H2O, the project is making a water filter to turn dirty water into clean water and if it did not work why. The thing that I did really well is making the water filter because I have already made one for another project so I just used the same things. Something that is did wrong I pressed the bottle to hard and all the water turned black because there was coal and I guess when I pressed it some of the things I used fell to the bottom of the water filter. I overcame that by rinsing out the water and waiting for it to go through a cycle twice and then testing it again.

My water filter design is you put water in the top and the water comes through the sand, gravel, and coal. I choose this because I have done something like this a couple years ago. And the water taste good for this water filter. My water filter works because the water goes through the bottle the sand, gravel, coal, sand, and gravel. It works by the water going through the water bottle and it drips into clean water. My water filter is the same as the ground water because it could be bad or you or good. It is different because my water is much safer to drink than ground water.

Yes it did change between 7.0, 7.1, 7.2 and 7.3. It varied the most was 7.3 the least was 7.0.
My hypothesis was if I use common, inexpensive materials readily available anywhere in the world, then I should be able to construct an effective water filter for use in areas where drinkable fresh water is scarce. To test this hypothesis, I constructed two simple, inexpensive water filter systems using one proven methods for purifying small quantities of water. There is a growing shortage of drinkable fresh water in the world. In the Third World there is a great need for people to have affordable water filters. The purpose of this study is to compare the effectiveness of two different inexpensive types of water filters.
My hypothesis was partially supported by the data:
1. The pH levels of water from my two filtration methods were brought into the SAFE zone

The relationship between my water and the groundwater was that my water was a pH of 7.2 and the groundwater is of 8.2. Both of the water was dark and dirty. My water was clear but when I pulled it out it turned black.My water represents the filtration process by filtering it in one of the cycles.

• Before 7.25
• After 7.1
• Change 0.15
• -log x =0.15
• or
• 10^0.15
• x= 1.91253754462

Before and after it was the same it was Acidic both before and after both of them were a 7.

LAB REPORT
Procedure
I will test water from Samples 1, 2 & 3 for purity in 2 different ways:

1. Gathering Samples
2.  From the source water, I will make three samples.

Sample 1

•  Remains unfiltered
•  Store in a capped 14oz clear plastic PET bottle
• Test for chemical content using water strips

Sample 2

1. Gather sand, gravel, charcoal, chlorine dioxide in the prescribed amounts
2. Cut the bottom 2 inches off of 32oz clear plastic water bottle
3.  With the cap on the bottle, put a small piece of cloth at the bottom of the bottom of the bottle
4. Remove the cap
5. Pour the prescribed ingredients into the open bottle in the following order from bottom to top

• gravel
• sand
• charcoal
• sand
• gravel

 Pour water from the source water into the sand/gravel/charcoal/charcoal filter
Collect water that trickles out of the filter in the water collector in a 14oz clear plastic PET bottle

My hypothesis was if I use common, inexpensive materials readily available anywhere in the world, then I should be able to construct an effective water filter for use in areas where drinkable fresh water is scarce. To test this hypothesis, I constructed two simple, inexpensive water filter systems using two proven methods for purifying small quantities of water.

My hypothesis was partially supported by the data:

1. The pH levels of water from my two filtration methods were brought into the SAFE zone
2. My water filtration methods were not able to remove Total Coliform – an indicator of fecal bacterial contamination in water. This might have happened because:
1. The gravel/sand/charcoal/chlorine dioxide filter used for Sample #2 did not contain enough filtration material to remove all of the contaminants.
2. The information I learned in this experiment can help me in the “real world” because I discovered that while drinkable water can be obtained with simple, easy to make water filters the methods used must be carefully constructed to deliver the proper results.
3. I would like to learn more about this subject because the supply of drinkable water around the world is becoming lower each year due to climate change, population growth and improper water usage. I want to help reverse this trend.

How Much Water Am I Using?

The class is H2O or Water. This is a STEAM course. My poster is intended to show that in the U.S. we use more water per person on a daily basis than some poor areas of the world. When I was calculating my total sum of water per day, I was very surprised at how much I was using. What I learned in class is that water is rare. That we have to conserve water. I was really proud of how I calulated my sum. 

AA. How Much Water am I Using Bus Ad. (2015)

For hygiene 30 gallons 30%, drinking/food 10 gallons 10%, laundry 20 gallons 20% and cleaning 20 gallons 20%. The country I looked up for comparison to see how many gallons of water they use per person is Uganda. The average person in Uganda uses 10 gallons of water per day. In Uganda the amount of water used for food and drinking was the same amount as me, 10 gallons. Overall I use about 70 gallons per day more then they do. It would take me to 2 hours and 4 minutes to carry water from the nearby water source. In the USA there are 550 gallons of water use per average person per day. If I had to do that before school and after school I would take 4 hours and 8 minutes. I would have to cut down or do my homework earlier. If I did this every day I would take 64 trips for one morning. If the USA uses 525 more gallons than Uganda we could cut down on taking showers and we could give the extra water to a many families in Uganda. If we compare the water usage around the world, in places where there is an abundance of water they use too much. In other places that barely have any and they don’t get much. Many people use too much in the USA and others places. If we don’t take 30-minute showers or use water to give plants food and just let the rain feed them we would save much water. We can use the extra of water and give it to other places that need it more. The blue line on the map above stretches from the USA Uganda.
