* Report, compare, and analyze the results of the soil moisture determination.

* Explain what the following quantities reveal about a soil, and using a soil phase diagram, define each one:

q
moisture content
(w) q porosity ( n) q degree of saturation ( S) q unit weight (g): s unit weight of the soil sample s unit weight of water s dry unit weight |
q
density (r):
s density of the soil sample s dry density s density of water q specific gravity of solids ( G)
_{s}q void ratio ( e) q relative density ( D)_{r} |

* Using the mass of your dry soil sample, estimate the volume of solids in your soil sample.

* Using the density of water, estimate the volume of water that was in your moist soil sample, before you dried it.

* Calculate the degree of saturation of your moist soil sample.

* Solve weight-volume problems that ask you to use the values of some soil properties to calculate the values of others.
