Abstract:
We cleaned up foul water to produce clean water to a point where it could be used to wash our hands with. We filtered the water by performing the procedures of oil-water separation, sand filtration, and charcoal adsorption. The purpose the Foul Water Lab was to learn how to execute the process of purifying water. It was significant because we purified water through three simple steps. The filtration of water is important because it is a necessity to to people around the world. I learned how simple it was to clean water to a point where I could wash my hands with it. I also learned how teamwork is important in each experiment because my team was very helpful to the whole procedure.
Procedure:
1. Make a data table.
2. Obtain 100 mL of foul water toa beaker and record the volume.
3. Record you observations before the treatment.
4. The the sample sit for a minute.
5. Remove as much of the upper liquid layer and place it in a test tube.
6. Add a few drop of distilled water to the test tube.
7. Record the volume of the remaining liquid.
8. Dispose the liquid in the test tube.
9. Poke holes in the bottom of a disposable cup with a paper clip.
10. Add premoistened gravel and sand layers to the cup.
11. Pour your sample in the cup. Catch the drained liquid in a beaker.
12. Dispose the used sand and gravel.
13. Observe the filtered water and record its volume and results.
14. Fold filtered paper.
15. Place the filtered paper in a funnel and moisten it lightly.
16. Place the funnel in a ring over a beaker.
17. Place one teaspoon of charcoil in an Erlenmeyer flask.
18. Wour the water into a flask, swirl it, then pour the liquid through the filtered paper.
19. If the filtrate is darkened by charcoal, filter the liquid again though a filter paper.
20. Pour the filtered water back into the graduated cylinder and record the volume and properties.
21. Dispose or save your water according to your teachers instructions.
22. Wash your hands.
Results:
Though all the prodecures of first oil-water seperation, sand filtration, and later charcoil adsorbtion, we were able the purify the foul water.
After oil-water seperation we didnt have the floating oil on the surface.
After sand filtration solid particles were seperated from the liquid.
After charcoil adsorbtion the water was completely clear.
We lost about 15 mL of liquid, but ended up with clean water like we first intended.
The aggregated data shows that the volume lowered as the water went through each step in filtration. This is the data gathered from each of the groups in the class:

The foul water ended up not being completely pure. There was electrical conductivity. We know this because we took a conductivity test and the light brightened meaning there is electrical conductivity.
We then used distillation. This is a process that separates liquid substances based on differences in their boiling points.

I really love your uses of photos Georgia Faith.
