Effect of oil spills on aquatic plants
The hypothesis that the plant in the beaker with a layer of oil on the surface will not be able to perform photosynthesis and stop producing oxygen has been proven to be true.
Millions of gallons of oil are being discharged into our oceans every year and this is causing serious environmental problems. The source of these oil spills are careless handling, offshore oil drilling, oil tanker leaks, natural disasters and war. Oil spills contaminate water, kill aquatic plants and animals, cause coastlines to become tarred and destroy the ecosystem.
The science fair project can also be repeated by limiting the light that enters the sides of the beaker by covering the sides with a cardboard.
The experiment may be modified to test for the growth of the plants, by measuring the weight of the plants before adding the oil and 3 days after adding the oil.
