After this 2 week experiment, a lot of data has been collected. As hypothesized in the beginning, the seeds treated with acid rain did not grow as much as those treated with regular water. At the beginning of the each Test, the seeds were all very small and hard. The pea seeds measured 1/4 of an inch, the corn seeds were also 1/4 of an inch, and the bean seedlings were 1/2 of an inch in length. In appendix A and B, the picture shows what the seedlings of both tests look like without any watering. The bags treated with water, Controls 1-6, showed the most growth over the bags treated with diluted lemon juice, Trials 1-6. The tables below show the average seed growth over a 15 day period. Only a few days were shown on the table to show the best growth days.

Appendix I and J shows pictures of Day 12 of both Tests. In Test 1 with Controls 1-3, the seeds were starting to turn a black color and having the paper towel become dirty. This was not mold, but the reasonings were unknown. Even though the seeds turned color, they still germinated. The pea seeds measured 3 1/2 inches, the corn seedlings measured 2 inches and so did the bean seeds. In Trials 1-3 in Test 1, all the seeds measured to be 1 inch. In Test 2 with Controls 4-6, the pea seeds were 2 1/4 inches, the corn seeds were 1 1/4 inches, and the bean seeds were 2 1/2 inches. In Trials 4-6, the pea seeds were 1 1/4 inches, the corn seeds were 3/4 of an inch, and the bean seeds were 1 inch. These seeds did not turn black, only the Control
