The Effect of Acid Rain on Marigold Plants (page 4)

based on 158 ratings
Author: Ryan T.

Application

The conclusions I reached by doing this experiment can be used in educating the world on the harmful effects of pollution from coal-burning factories, power plants and transportation. It will motivate people to take corrective actions personally, support additional research into corrective matters by governments and support legislation to limit pollution by factories contributing to acid rain conditions.

As you can see from this experiment, acid rain is very deadly. It affects all organisms and ecosystems in our world. We need to find ways to help stop pollution from getting into the air and to protect plants, buildings, monuments, lakes, streams and wildlife from the harmful effects of acid rain. We need to communicate to the public the problem so that we can take the corrective actions of polluting less, correcting damage and establishing controls to limit pollution in the future. The longer we wait to seriously attempt to reduce acid rain, the more endangered our Earth will become for everything and everyone who lives on it.

Bibliography

Books
Parks, Peggy. Acid Rain. Detroit: Thomson Gale, 2006. (Excellent book that went over how acid rain is formed, the effects, how it is spread and finally, how it can be stopped. It also has a good glossary of terms that helped me understand the science.) 

Petheram, Louise. Acid Rain. Mankato, MN: Capstone Press, 2003 (This book went into more detail than the first book. It also talked about measuring acid rain with the pH scale which really helped me in my experiment. It also had the detailed effects on nonindustrial areas, human health, forests, crops, water life and buildings. It talked about solutions.)

Retail Stores

Home Depot - Jeffrey Strong, Garden Manager - gave me good information on what types of plants grow quickly and flower. After initially looking at ground cover, we focused on flowering plants, deciding on the marigold.

Orchard Supply Hardware - Steven Halloway, Garden Supervisor - directed me to marigolds as a quick-growing plant that flowers almost immediately upon bringing them home.
