"For my project, I tested how different pH levels effect the decomposition of a spinach leaf. Each of the substances were used to represent acid rain and the affects it has on plants. I hypothesized that the lower the mixture is on the pH scale, the more the leaf would decompose. I used five different substances(all mixed with distilled water): lemon juice, black coffee, bleach, baking soda, and unaffected distilled water. I ran this experiment over the course of two days, adding more of each substance every twelve hours."
