The purpose of this test was to see how quickly water percolated (or drained) through our soil compared to some other substances. To do this, we created funnels from bottles and poured water through them, keeping track of the time it took for it to drain a measurable amount to the bottom. Illinois soil is known to be pretty full of clay, but we only found a little bit in our composition test and the water drained through it quite quickly.
The soil drained 28 mL of water in 13.2 seconds. 28 mL/ 13.2 sec.= 2.12 mL/sec.
The sand drained 18 mL of water in 18.5 seconds. 18 mL/ 18.5 sec. = .97 mL/sec.
The clay drained 40 mL of water in 12.8 seconds. 40 mL/ 12.8 sec. = 3.13 mL/sec.
