OverviewOil spills seems to be a way of life. Most of the oil spills we hear about on the radio and television occur in the ocean. Oil floats on water. The old saying oil and water dont mix is basically true. Petroleum products are a big pollution problem in our environment. Scientists have discovered bacteria that digest oil and cause it to degrade in the environment. These bacteria can help when there are oil spills. How does oil spill effect plant life? Obviously if oil coats a plant and prevents it from getting water, the plant will die. But just because oil is present, does it prevent the plant from getting water?

Problem:Can plants continue to grow properly even if there is oil present along with the other factors they need?

Hypothesis:I think that if supported with the discovery of oil degrading bacteria and with the help of hydroponically grown plants, then plants can continue to grow properly with oil present.

Experimental Design:Variables Control: o Plant 1(No Oil received) Controlled Variables:o Amount of sunlight o Amount of soil o Type of soil

o The condition and type of the Plants

Manipulated/ Independent Variables:o The type of liquid/ nutrients supplied/given to the plants

Responding Variables:o The growth rate and health condition of the plant.

ProcedureUse one hydroponic plant as a control; keep all conditions exactly the same as the experimental plants. Pour about one inch layer of cooking oil on one of the experimental plants and a one inch layer of motor oil on the other one. Put the plants where they will get plenty of sunlight. Be sure they get enough nutrient solution. You can also hypothesize that the oil on both plants will either kill the plant, make it less fit for consumption, or cause it to become weak. Record data daily on the condition of all the plants. At the end of a specific period of time, four weeks for example, determine whether your hypothesis was correct. You might want to specify the period of time in your hypothesis so it is either correct or incorrect for that length of time.
