Acid Rain Lab
The purpose of this experiment was to study the effect acid rain has on seed germination and after performing this experiment is can be concluded that acid rain has a negative effect on seed germination. When seeds are soaked in an acidic solution the process of germination slows. Acidic solutions, while do slow growth of a seed, they do not kill the seed. A seed can be dormant for a majority of its lifespan, seeds watered with acid solutions stayed in a dormant condition. For example, trial three (3) part one (1) and two (2) both experienced germination. Whereas, trial one (1) part one (1) and two (2) and trial two (2) part one (1) and two (2) experienced very little to no growth; these seeds were dormant during the experiment. Twenty (20)

of the sixty (60) seeds germinated. The Twenty (20) seeds that germinated were all in the control group watered only with tap water; meaning all acidic mixtures slowed the growth process of a seed enough that the seeds had not germinated. These results prove that the acidity of a solution affects its growth. The acidity of the tested solutions affected the color of the mold also; this was an uncertainty in the experiment.
The seeds that were watered with acidic solutions developed a rust colored sold along the outer edges of the paper towel. While the most successful trials, water with tap water, developed mold differently. One of the controlled trials developed very little mold, but the mold was bright colors like yellow and pink. The other controlled trial developed large amounts of different types of mold. This trial also developed a small amount of yellow and pink mold but a large amount of dark spore-like areas. These areas were a black color and were scattered about the paper towel. This test also had light brown colored mold in various areas. The seeds also molded in the trial creating a thick web a on top of the paper towel spreading between the seeds. This we like mold also had small black dots about the size of a grain of salt. The two (2) trials tested with scid liquids both had a pH value of 3 when diluted with water. This proves that not only do acidic solutions affect the growth of seeds but also the growth and variation of mold. Overall this experiment was very beneficial and can be used in further research done on the subject of seed germination. This experiment can help scientists, farmers, and students study and compare the effect that “acid rain” has on a small scale to then later apply this research in everyday
life.
