Oil-Absorbing Polymers and Soil Cleanup
Medium
Can a special polymer pull motor oil out of contaminated soil well enough for seeds to grow again? Oil spills poison the ground. This project tests whether oil-absorbing polymers can reverse the damage.
You prepare four pots of soil. One stays clean. The other three get mixed with motor oil. You treat one oily pot with a water-absorbing polymer. Another gets an oil-absorbing polymer. You plant 20 green bean seeds in each pot and count how many sprout over 10 days.
The results show which treatment helps seeds germinate in oil-damaged soil.
Hypothesis
The hypothesis is that oil absorbing polymers can effectively rehabilitate soil contaminated with motor oil and render the soil suitable for growth.
Method & Materials
You will prepare four pots of soil, one with just soil, one with soil and motor oil, one with soil, motor oil, and water absorbing polymer, and one with soil, motor oil, and oil absorbing polymer. You will then place 20 green beans in each pot and water them once a day.
You will need 80 green bean seeds, 4 pots, enough soil for the 4 pots, 1 bottle of motor oil, 1 packet of oil absorbing polymers, 1 packet of water absorbing polymers, water, a spade, and a black marker pen.
Results
The results showed that the pot without any oil had the most number of beans that germinated, followed by the pot with motor oil and the oil absorbing polymer. This proves that oil absorbing polymers can effectively rehabilitate soil contaminated with motor oil and render the soil suitable for growth.
Why do this project?
This science project is interesting because it shows how oil absorbing polymers can be used to clean up contaminated soil and make it suitable for growing plants.
Also Consider
Consider repeating this science project using different types of contaminants like pesticides or grease. Also, consider monitoring the growth rate of certain species of plants in contaminated soil to ascertain which species are more hardy.
