In this lab we poured the water into the filter and used a timer to see how long it took for the water to go through. A problem we came across was that there was some water left over from previous groups which could have affected the time and amount of water that went through the filter. The soil samples contained varied amounts of fine gravel and large rocks in which the location of them affected how the water traveled through. This plays a role in pollution and everyday usage by showing how pollutants such as lemon juice and vinegar take longer to filtrate affecting our everyday usage.

 * Lab 3: Water Testing (Megan)**

In our water testing lab we tested water samples 1 and 3. We tested for ammonia nitrogen, the pH, chlorine, chromium, copper, iron, nitrate nitrogen, phosphorus, silica and sulfide. It is important to understand the makeup of your water, to know water should and shouldn't be present, and to also understand that a small trace of an abnormal substance won't kill you, but that awareness and understanding are important. In the process of our experiments there was a lack of iron indicator, so we were unable to test for iron in our samples. Our results supported our initial expectations, of minimal pollution, basically normal levels of the samples were discovered.

After we tasted the waters we discovered that sample A was spring water, sample B was distilled water, and sample C was purified water. The paper material of the cup affected the taste of the water. Water sample C had the highest score while water sample B had the lowest. The scores were based on their color, odor and taste.

 * Lab 5: Soil Separation (Megan)**

Using a mason jar half filled with soil (the third bucket), 2 teaspoons of fabric softener, and the rest filled with water, we recorded the first five minutes of the settlement of the particles then again the next day. After the first three minutes the soil started to level out, but at the time there were only two distinct layers of soil, not three. The top layer of soil was lighter in color than the one on the bottom. The next day, three layers were evident. Of the twelve cm jar, half was taken up by soil. there was water on top, then a cm of silt, then a cm of clay and then four cm of sand/sediment. By using the soil triangle we were able to identify our soil as a sandy loam, with 66 2/3% sand, 16 2/3% clay and 16 2/3% silt.

distilled, the top layer of soil is lighter || Lab 6 NPK + pH (Amanda) We filled the test tubes with water then added pH and nitrogen, phosphorous and potassium tablets, shook it, and let it sit until we were able to observe the color change. We discovered that the pH was 7 ( a light puke green color), nitrogen was a very pale yellow which indicated there was a very small amount, phosphorous was clear also indicating a low amount, potassium was high (it was more pale than grey). A problem we came across was that the potassium tube was dirty. NPK Potassium || high || Pale grey || Phosphorous || low || Almost clear blue || Nitrogen || low || Pale yellow || PH 7 || Light puke green || Conclusion (Amanda) In conclusion, this lab fest had us relate soil and water to our everyday needs. In lab 1 we learned about natural filtration. In lab 3 and 4 we learned about water testing. In lab 5 we learned about soil separation and in lab 6 we learned about NPK and pH of soil. These labs showed us how water and soil relate to each other through daily usage, aquifers, and recharge zones which in all affect humans and animals in their daily lifestyle.
