CORN COBS AS WATER FILTERS STATEMENT OF THE PROBLEM: How effective and efficient are the corn cob filters? SUBPROBLEMS: a) What is the relationship of the structure of the corn cobs in the water filtration? b) On the scale from 1 to 10 (10 being the highest), how pure is the filtered water? c) How many times can we use the corn cobs to filtrate unusable water before changing the cobs? d) Can we use the corn cob water filters even when corns are not in season? e) Can we use the corn cobs that are discolored due to the exposure to rain? ASSUMPTIONS HYPOTHESES  Corn cob water filters have the same efficiency and effectivity with the commercial water purifiers.  Corn cob water filters are more affordable and convenient to the farmers and residents of rural areas than commercial water purifiers.  It takes an effort and a considerable span of time to construct a corn cob water filter.  When you will use a corn cob water filter, there will be less corn cobs to be wasted.  Since corn cobs are organic, the corn cob filters are not harmful to the environment. Null Hypothesis: There is no significant difference between the corn cob filter and commercial water purifiers. Operational Hypothesis: There is a significant difference between the corn cob filter and commercial water purifiers.
