Pollution and Green Chemistry Science Fair Projects

You can design a science fair project that studies pollution or addresses green chemistry. Topics include air pollution, water pollution, soil pollution, and green chemistry, which seeks to minimize the pollution generated by chemical processes. What type of car antifreeze is safest to the environment?Does the presence of detergent in water affect plant growth?How effective are natural mosquito repellents? Are they safer for the environment?What is the effect of a certain chemical in water on algae growth?How is biodiversity affected by the level of pollution?How closely does the pH of soil relate to the pH of the water around the soil? Which types of soils resist pH changes from pollution the best?What are some natural herbicides, pesticides, or algicides? How effective are they? How safe are they for the environment?How effective are house plants at reducing the concentration of organic air pollutants? Is the level of air pollutants lower in areas with a large number of trees compared with relatively nearby areas that have few plants?What might you do to detoxify run-off?Do the chemical preservatives used in packaging break down or do they remain in soil after the packaging has been composted?
