The class I took was called water. We learned about water filters, how they work and why people need them. Filters are similar to the earth because the earth has different layers and that's similar to the way my filter was made. My favorite part of this course was when we went to the water filtration plant and saw where Chicago gets its water. It was amazing to see the massive plant that manages to produce 1 million clean gallons of water per minute.

- Cup
- Gatorade bottle
- Sand
- Gravel
- Foam
- Stick
I got my materials from friends and from my teacher.
Step 1- Put a piece of foam into the cup
Step 2- Put sand on top of the foam
Step 3- Put gravel on top of the sand
Step 4- Put another piece of foam on top of the gravel
Step 5- Then out bigger pieces of gravel on top of the foam
Step 6- Then add sand and another layer of foam
Step 7- Then put the Gatorade bottle under the Starbucks bottle
I used this filter design because it is similar to other filter designs because it has the different layers and the water catching device at the bottom.
My filter works because the water goes through the different layers of water and the different layers take out the contaminants.
My filter is similar to underground filtration because they both have different layers of materials that filter out contaminants.
The source of my water is river water but I added many contaminants such as mushrooms, screws and other things. The original ph was 3.6 and after it was 4.1 which means there was a difference of .5 this is in the acidic side of the scale.
10^-4.1=.000079
10^-3.6=.00025
3.16 diffrence in PH
