Objective: The objective was to determine the act increased sullenness in watering solutions would have on the step-up, prime quantitys and sprouts, and health of marigold plants so that inferences could be made about the effect acid rain is having on our environment.  Research led to my hypothesis that the change over in height of the plant would decrease by 25% from the figure for each 1pH level, the flowers and sprouts growth would decrease by 10% for each 1pH change and the observed health of the plant would radioactive decay. Materials and Methods: Six acid-forming watering solutions were made by adding vinegar to distilled water, with differing levels of acidity ranging from pH3.2 to pH6.0. The solutions were employ to water 29 similar marigold plants (replanted to create identical conditions) in groups of 5 for 10 days. Each day, the plants heights were measured, the number of flowers and sprouts were counted and ecumenical observations of the plants health were completed. Results: Growth rate declined from the control (pH6), beginning at an 8.3% decline at pH5.5 and ending in 1252.8% at pH3.2. The change in number of flowers increased, then declined at below pH 3.75 leading to a decrease from pH6 in flower growth by 34.37% at pH3.2. The change in number of buds or sprouts compared to pH6 dropped by 26.7% at pH 5.

5 to a decline of 475% at pH3.2. Combining the increase in buds/sprouts and flowers, there was a decline in growth compared to pH6 at lower than pH 5.5. The counts declined by 66.7% at pH4.3 to 298% at pH3.2. The higher acidity levels led to the foamy appearance of plants beginning on day 10 with pH 4.3 and earlier with more acidity, resulting in day 4 with pH 3.2.   Increased acidity had a negative effect on the health and growth of plants. The growth rate and rate of flower and sprout growth combined declined. The observed health of the plants declined immediately. Conclusions/ reciprocation: Increased acidity had a clearly negative effect on the health and growth of...
