Hypotheses:

Activity 1.

My hypothesis for this project is the results will show Sand 50% and Silt and Clay will both show 25% each .

Activity 2. My hypothesis for activity 2 is that the “Sand” sample will have the highest porosity and the “Clay” sample will have the lowest.

Activity 3.

My Hypothesis for this activity is that Soil Sample A and Sand sample will be more acidic due to the shorter times of the first drop emerging in activity 2.

Activity 4.

My hypothesis for this activity was a little difficult to come up with due to both of my samples coming in with neutral PH levels. Since the “Sand” sample was more dense looking to me, I would say it would have the higher Potash level. I also believe this same sample will have the higher levels of Nitrogen and Phosphorus.
