Water Quality Lab (Laura) In this lab we taste-tested 3 different types of water given to us. Sample 1 - Color = 3, Odor = 5, Taste = 2, Total Score = 10 Sample 2 - Color = 3, Odor = 5, Taste = 3, Total Score = 11 Sample 3 - Color = 3, Odor = 5, Taste = 4, Total Score = 12 1 = Poor, 2 = Below Average, 3 = Average, 4 = Above Average, 5 = Excellent

We Concluded that none of the samples had a different color or odor than the rest of the samples. The only thing different was their taste. Sample 3 received the highest score form our group with a total score of 12 and Sample 1 received the lowest score from our group with a total score of 10. We guessed that sample 1 was tap water, sample 2 was bottled water and sample 3 was water from the water fountain. **

Porosity and Permeability Lab (Miguel Hechavarria) In this lab we measured the porosity and permeability of two samples of soil. We tried to find the grain size and used our results from our experiment and the grain size table to figure out how big the grains wore, the size class and the sediment/rock name.


 * **__Material__ ** || **__GrainSize mm__ ** || **__Porosity mm__ ** || **__FlowTime sec__ ** || **__H20 Recovered__ ** || ** __Permeability ml/sec__ ** ||
 * **FineSand** || 1/4 || 30 || 107 || 11 || .10 ||
 * **Soil** || 2 || 100 || 233 || 44 || .19 ||
 * **MedSand** || 1/2 || 75 || 66 || 10 || .15 ||
 * **Top Soil** || 3 || 275 || 222 || 138 || 1.13 ||

In conclusion, there were four types of soil in our samples. They were fine sande, soil, medium sand and top soil. Top soil is the most permeable and the most porous.

Natural Filtrations Lab (Alli Cook)  In this lab we tested the ability of four different materials to filter through natural sediments. The materials included vinegar, lemon juice, soil, and food coloring; water was used as a control. 250 mL of water was poured into five separate beakers each. Then the materials were added to the water; one material per beaker. 15 mL were added of the vinegar, lemon juice, and dirt, and 15 drops of the food coloring. We then slowly poured the contents of the beakers into separate filtrarion systems. Next, we timed how long it took for the contents of each beaker to fully go through the system. We observed that the lemon juice took the longest to filter through the system (12 min 17 sec), and the food coloring took the shortest amount of time to filter through (34 sec). However, when poured through the system, the food color still remained in the water, thus not not truly being filtered. The soil, however, was filtered out of the water when it passed through the system.
 * Beaker || Time taken to filter ||
 * Vinegar, 15 mL || 7 min, 6 sec ||
 * Lemon Juice 15 mL || 12 min, 17 sec ||
 * Soil 15 mL || 1 min, 39 sec ||
 * Food Coloring (15 drops) || 34 sec ||
 * Water (control) ||  2 min, 50 sec ||

__**Mason Jar lab (Ashleigh Weddington)**__  In the mason jar lab we added dirt, water, and fabric softener to a mason jar. After all the elements were added we had to let the mason jar sit and let all the layers separate. After the mason jar settled we measured how much total material was in the jar, then we measured the amount of each layer.


 * < **Measurement of all material** ||< 11.5 cm ||
 * < **Measurement of organic material** ||< 3 cm ||
 * < **Measurement of fabric softener** ||< 5 cm ||
 * < **Measurement of dirt** ||< 3.5 cm ||

We concluded that the fabric softener caused the organic material and the dirt to separate. The organic material stayed on top of the mason jar and the extra dirt stayed at the bottom.

**__Core Lab (Ashleigh Weddington)__ **

During the core lab we had to core a section of dirt up from outside and bring it inside to draw what the dirt looked like inside the core. After we drew the dirt we had to take soil and put it through a series of filters. the filters were stacked on top of each other. The soil was put into the first one and we shook them to see how far down we could get the soil to go.

After shaking the dirt through the filters we concluded that the dirt could not break down into small enough to make it past the third filter. there were only small particles of dust on the fourth level.
