Investigating How Much Water Able To Pass Through Three Different Types Of Water

t it was tested how much water was able to pass through three different types of soil. The control in the experiment was no soil for the water to pass through and an average of 39 ml. Passed through. Variable one was gravel and an average of 34 ml. Of water flowed through the soil this means 5 less ml. Of water passed through the gravel then no soil. Variable two sand, sand let an average of 25.3 ml. Of water pass through it 13.7 ml. Less than no soil (39 ml.) . Variable three potting soil, an average of 36.6 ml. Of water passed through the potting soil and ended up only 2.4 ml. Less water passed through then no soil (39 ml.). When the experiment was finished it was found that potting soil let the most amount of water through with an average

These results were collected because of the In the experiment it was tested how much water was able to pass through three different types of soil. The control in the experiment was no soil for the water to pass through and an average of 39 ml. Passed through. Variable one was gravel and an average of 34 ml. Of water flowed through the soil this means 5 less ml. Of water passed through the gravel then no soil. Variable two sand, sand let an average of 25.3 ml. Of water pass through it 13.7 ml. Less than no soil (39 ml.) . Variable three potting soil, an average of 36.6 ml. Of water passed through the potting soil and ended up only 2.4 ml. Less water passed through then no soil (39 ml.). When the experiment was finished it was found that potting soil let the most amount of water through with an average of 36.6 ml. Of water passed through, gravel let the second most water through and sand let the least amount of water through. If three types of soil are tested then gravel will let the most amount of water through. The hypothesis in the experiment was not supported. The hypothesis was not supported because the potting soil let the most water through because it let 36.3 ml. Of water pass through. The gravel let the second most water through letting on average 34 ml. Of water through. Sand let the least amount of water through because only 27 ml. Of water

This was known because we had an inconsistency in the results by a large margin and then we found water had spilled out of the funnel. Another error or problem was splashing water because of how high the funnel was from the beaker. This problem could be and was resolved by lowering the funnel closer to beaker so there is no splashing to get the most amount of water into the beaker. If the experiment were to be continued then testing more soils would be a way to expand the experiment to find out how permeable and the porosity of different types of soil. More questions that came up during the experiment was how much water was absorbed into the coffee filter and if it would effect my experiment results. In conclusion gravel allowed the most amount of water through, potting soil let somewhere in between the two through and sand let the least amount of water through and permeability of the soils. One reason that potting soil had the most water pass through is mainly because potting soil has a high porosity, higher than the other soils that were used in the experiment, this matters because since the soil has more pores there are more pores to connect with each other which cause the soil to be more permeable meaning how easily or how much water can flow through the soil. This goes for the rest of the soils that were tested, the higher the porosity the
