Plant growth is affected by its surrounding environment. It can be used to measure air quality by their growth. We investigated the effects of air pollution on plant growth by burning charcoal, fire starters and paper to simulate polluted air. We applied this method to our experiment to discern what environment plants thrive in. To evaluate how well the plants grow, we have concurrently measured the height and growth of each plant in the different setups. The control plants grew to 22 cm in the end, as compared to the other plants exposed to less polluted and more polluted air, which grew 14.5 cm and 9.5 cm respectively. This indicated that plants, or green beans specifically, thrive in any environment with the least amount of air pollution. Graphs and tables were developed to be used as observation tools to inform people who are interested. Merits and limitations of results will be discussed as well as ways to further improve, develop and advance our experiment, as well as discuss potential directions for better research will be taken note of. Our experiment can be used to inform people in the agricultural business a recommended location for healthy plant growth.
