Increasing Energy efficiency in city water filtration

My hypothesis is that one filter will not clean the water but all five together will. Furthermore, I guess the pumice will be the best filter and the charcol will be the worst, and contaminate it more.

Testing different materials to determine which one(s) will best filter the water. I tried using a variety of different materials until I determined which ones best cleaned the water collectively and which ones further contaminated the water.

My independent variable was the use of the same water with each test. And my dependent variables are the different materials used to filter the water. Coffee filter, charcoal, cotton balls, noodles, and rice. Pumice and sand were originally used but they ended up making the water more dirty so I discontinued use of those matierals.

First - I made '6' desending stairs (the nummber can verry it only depends on how meany filters I wanted)

Secent - I cut my '6' cupse in haf and used a hot glue gun and glued the piping to my cups

Thered - Then I put My meterels In my cups, sucked all the air out of the tubs and wacht it filter throu

In my water filter the charcol dirteed the water even more, and wen I tried to put saned and pumice went throu the cup and also dirteed it more to.

Coffee Filter- Helps get rid of big chunks in the water. With a magnfying glass I could see a little bit of build up when i poured my sample of the school's tap water

Rice: It further stops any small particles

Charcal - Can get rid of the bacteria or toxins. I noticed that the water looked darker than before but I know charcal can be used as a detox.

Cotton Balls - I noticed they took away some of the colour

Dried Pasta - Also a good method to take away larger particles.

There are other ways of clarifing whater which include distilling it, stone boiling, or using plants as filteration, sedimentaion, solar water, and purifing.

As canadians wen need to find a less expensive, less uesed resorses to purifi our water.

Everthing went prity well, there was one time wen we thout it would not werk and that was wen I put pumise and sand in the cups and it fillterd throu. But i used my problum soving and changed them to diferent seplise.

I acknowledgemn that my teacher gave me more to lete me work on it. And that my mom and brother help me to make my progects.
