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.

Science Concepts Learned

Soil Contamination

Oil spills get harmful stuff into the ground and stop seeds from growing, making the soil unsafe. Special oil-absorbing polymers may reverse that damage. This project mixes motor oil into soil, treats it with polymers, and counts how many green bean seeds sprout over 10 days.

Pollutant

Motor oil added to soil is a pollutant that poisons the ground and stops seeds from growing. This project tests whether oil-absorbing polymers can clean contaminated soil well enough for green beans to sprout. The results show whether removing the pollutant restores conditions for living things.

Oil Spill Cleanup

Oil spill cleanup doesn't stop at the water's edge — contaminated soil also needs treatment. Oil-absorbing polymers offer one approach: they pull oil out of ground that a spill has poisoned. You can test how well this works by planting seeds in treated soil and counting how many sprout over 10 days.

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.
