** __Lab 1: Natural Filtration__ ** The procedure of the lab included filtering different types of solutions through varying layers of sediment. We poured the solutions through the sediments and waited for them to filter. The water came out and particles are captured in the sediments along the way.

 This lab is set up to determine the amount of sediment that water can hold and the rate of flow. We poured water on top of the sediment until it pooled to measure porosity, pouring in the rest to measure the rate of flow for permeability. There was a slow rate of flow and much of the water remained in the sediment. 
 * __Lab 2: Permeability and Porosity__ ** 

We mixed chemicals in the water to test the chemical compositions. We tested for chemicals, such as phosphorus, copper, iron, and cyanide. We concluded that there weren't many chemicals, besides the copper and phosphorus. 
 * __Lab 4: Water Testing__ ** 



The purpose of the lab was to find physical differences between different types of water. We tasted distilled, spring, and purified water to find the taste, color, and odor differences. We concluded that the purified water was clearest and had the best taste, whereas distilled water had the poorest quality.

**__Lab 6: Mason Jar__**  Soil separation figures out the different densities of the sediment. We used the soil triangle to determine the different types of sediment after letting water set overnight. We found that the percentages of sediment match with those of clay.



**__Lab:7 NPK__** __**​**__The NPK test determines whether there is nitrogen (N), phosphorous (P), or Potassium (K) in samples of water. ​For the test, a uniform test solution was made and put into three test tubes. Each test tube had a test tablet of N, P or K placed inside of it. The test tubes all showed low amounts of N, P and K within each test solution.



This lab was to test the Ph level of a soil sample. Distilled water was mixed with a teaspoon of water in a test tube and then a Ph tablet was placed inside. After 5min. there was no significant change in the water color with the dirt (light green) thus showing that the soil sample was neutral.
 * __Lab 8: PH Test__**

Core sampling is used to see how the composition of layers in soil change based on the depth of a sample. The samples were taken outside of the classroom, and the layers within the soil were recorded. There were three distinct layers within the soil, a biotic layer of plant debris, a sandy layer and the deepest layer being a culmination of sandy soil and small rocks.
