The goal of this project was to create a way to clean water. My group spent a while brainstorming because we had to think how when people would be in our group during the project, (in the end we were out for state testing at the same time). Since our group could not decide if we wanted to make a water filter or water still we chose to do both, the filter would remove any particles and the still would remove any dissolved substances. We chose to use natural materials to simulate a river filter. We tested pH level, TDS, and volume after each step to see the progress of the water filter.
This is what our project looked like:
Content
pH levels:
how acidic a liquid is, water has a pH level of 7, drinking water should be as close to 7 as possible
Acids:
something that has a pH above 7
Bases:
something that has a pH below 7
Total dissolved solids (TDS):
measure of all inorganic and organic substances present in a liquid in molecular, ionized or micro-granular suspended form
Solution:
a liquid mixture in which the minor component (the solute) is uniformly distributed within the major component (the solvent)
Solvent:
can dissolve other substances
Solute:
a substance that is dissolved in a solution
Solubility:
chemical property referring to the ability for a given substance, (the solute), to dissolve in a solvent

The activated charcoal is able to filter out impurities through a process called adsorption. Pollutant molecules in the water to be treated are trapped inside the pore structure of the carbon substrate

Reflection
One thing I wish I learned in this project was to always have a back up. A deer had knocked over part of our water filter, so we had to reset up the experiment which took an extra day. This contributes to critical thinking because should have thought ahead when working on our project. Another pit in this project was we had to do a lot of waiting, we could have worked on our power point, so we wouldn't have to do it all in one day.
One thing that I learned in this project is how modern scientists are combating an important issue in today's society. Since I already knew everyone in my group and we were friends, we thought it would be hard to stay focused, but I was able to lead my group to make sure we didn't get distracted.
