Using Gravitational Force as a Measurement Tool

Activity 1
Record your data from Activity 1 in the boxes below. Enter the data for the sample you used in each trial (5000 rpm, 10000 rpm, etc…) in the appropriate columns and the corresponding g-force, number of layers, and position of layers position results.

You will need to use the following formula to assist with your laboratory report: G-force =0 00001118 x radius of centrifuge arm x (rpm)2 The radius of the centrifuge arm for this instrument is 10
Enter the data for the sample you used in each trial (0.5, 1.5, 2.0, and 2.5 grams/ liter cesium chloride) in the appropriate columns with the corresponding g-force, number of layers, and position of layers results.

Cesium Chloride grams/liter | 0.5 | 1.5 | 2.0 | 2.5 | Number of Layers | 2 | 5 | 5 | 6 | Position of Layers | One layer at top of tube and one layer filling a little more than half the tube. | Two layers at top of tube and three split layers filling half the tube. | Two small layers at top of tube, one small layer in middle, and two medium layers at bottom of tube. | Two skinny layers with one medium layer at top, one layer in middle, and two layers at bottom. |

Explain what happens to the drag as the cesium chloride concentration increases. The drag decreases as the cesium chloride concentration increases. Which is likely the best cesium chloride concentration to separate the components of this soil sample? Why? The best cesium chloride concentration to separate the components of this soil sample is 2.5 grams/liters because there are more layers so there would probably be more components separated in that concentration. Describe in which layers you are likely to find the organic matter, gravel, sand, silt, and clay at the following speeds: 0.5 grams/liter of cesium

Influences on Soil Nitrogen Mineralization: Implications for Soil Restoration and Revegetation Introduction Nitrogen is a macronutrient essential to the growth of plants and is also one of the most deficient nutrients in most soils. Insufficient levels of available soil nitrogen limit microbial growth and decay and growth of the plants themselves. Because site disturbance adversely affects the flow of nitrogen through soil-plant-microbial systems, the re-establishment of the cycle of nitrogen…
