Soil Lab

Which soil has the greatest permeability: fine sand; coarse sand; or soil? The permeability of three types of soils and the movement of ground water on land has been an investigation for the class. Three types of soils were presented to them: fine sand, coarse sand, and plant soil. They were given the instruction to slowly pour 50 ml of water through on the soil and calculate the time it took for the water to pass through as well as the amount of water collected from each soil type. From this experiment, each student was able to identify which soil had the greatest permeability and which had the least permeability, and was therefore able to explain the movement of ground water that we see from day to day.
