Filtering Water
For our second Action Project in our water class, the members of the freshman class all made water filters. We made them after visiting the Jardine Water Treatment Plant, where we saw a cross section of groundwater filtration. It helped us see how filtration actually worked, which we carried into our project as an example of one effective way to make our own filters.
I assembled the filter using things I already had in my house (the mug and tea infuser), things in my yard (the dirty water, gravel, and rocks), and some sand we had in a closet for some reason. This meant it was very cost effective, I didn’t even have to leave my house to get what I needed!
I knew this would work to some degree, because it’s basically an expedited version of what has been happening in nature for years. Most of the Earth’s water is underground, meaning it has gone through this process to get to the state it’s in now. Usually, it goes through finer layers, like sand first, before eventually passing through rocks to get to it’s (semi) final destination.
Question:
How can I make a functional water filter that would make dirty water visibly clearer?
Hypothesis:
I think that my water filter will make my water visibly clearer.

Procedure:
- Assemble filter
- Place filter in mug
- Pour dirty water into filter
- Drink
- Wait no don’t
Conclusion/Summary:
This experiment investigated replication of groundwater filtration. In order to study the problem we went to the Jardine Water Treatment Facility, where we saw a cross section of ground water filtration. My results showed that the filter was successful , which proved my hypothesis correct. I think the results are accurate, because I used a pH tester to check them. One way I could improve the accuracy of my results would be by checking with multiple pH testers if I were to repeat this.

.
On the pH scale, I got the level from 6.8, which is more acidic than drinking water to 7, which is the level of tap water. It moved 0.2 points away from acidity after filtration. Although it is a small difference, it is not negligible.
-log X = 0.2
This AP showed me how even simple, quick filters like my own can somewhat change water cleanliness.
