Filter Dirty Water Experiment

First thing is to make your hypothesis on how to filter dirty water like mine “My hypothesis is if I use one cut bottle and layer it to be pebbles, sand, cloth, charcoal, then cloth, sand, and pebbles it filter the water will be cleaned.”. Then you start to build hypothesis, so start by getting a bottle, cut the bottom of the bottle like two inches of it. You take the cap off the bottle then get two coffee filter and use two rubber bands to tie it to the cap of the bottom. Then add about a inch of pebbles of to the bottle, and then about a half inch layer of sand, a layer of cheesecloth. Next is a layer of charcoal, layer of cheesecloth, then a half layer of sand, finally a layer one inch pebbles. Your hypothesis is made, but it is not time
to test it. The first thing to test before testing your filter is to test water at the normal form.
Grab a 40 mL beaker and fill the normal water in the beaker to 40 mL and grab a pH tape then put it into the water. Take the pH paper out of the water and match it to the best similar color and record the data, the pH of normal water is 7. Next is to test the conductivity of the water, grab the conductivity probe by putting into the water and hit the green arrow. Let the probe be in the water for 30 seconds, so when it is at 30 seconds hit the red square to stop it and record the data. The conductivity of normal water is 503, the next step is testing the turbidity of the water. To test the turbidity you would use the colorimeter by pouring the water into a the clear square container and close it, it should have like 3/4s of the container of the water. And you would record the data that the labquest says, the turbidity of normal water is 0. You would do those same steps for the dirty water before the filter and record the data, the data shows the pH to be 5, the conductivity to be 4280, and the turbidity to be .70. Finally you will be able to start your filter, grab the beaker with the dirty water and put it through your filter. After that you want to do those some steps to the water that comes through your filter and record the data, the pH is 7, the conductivity of the water is 1,223.3, and the turbidity is .024. The result changed the pH back to normal water, but not the
others. You can change your filter and test the new dirty water again or keep the data. If you test the filter again, but this time add a layer of cotton between the two layer of sand that is between the charcoal. Places the water through your filter and test the new water with all the previous steps then record the data. The second test was the pH changing back to 7, the conductivity 1,123.5, and the turbidity of .021. The data was closer to the normal water data, but it is not the same still. That is the end of the lab, so the only thing left to do is to clean up the lab area and materials you used during the lab.
