Abstract

In this experiment, the effect of acid rain on duckweed growth was tested. The purpose of this research project was to find just how harmful acid rain is to aquatic environments as it is starting to become a major issue in today's world. As humans we already know that acid rain can be harmful to our crops, but this experiment clearly showed the damages acid rain does to animals and plants living around us. It was hypothesized that when duckweed was placed in an environment with a lower pH than the duckweed will grow more slowly than if it were placed in a neutral pH of 7. In this experiment there were fifteen petri dishes each containing 50 duckweed pods. The fifteen dishes were split up into three groups of five, each group representing a different pH level. One group was pH 3, one was pH 5, and one was pH 7. The duckweeds growth was observed over a 12 hour period and data was recorded. In this experiment, the hypothesis was supported the fact that the duckweed died faster when placed in an environment with a low pH. The pH 3 group died the fastest then the pH 5 group would've been next, and there wasn't a significant amount of change within the pH 7 group.

As humans we already know that acid rain can be harmful to our crops, but this experiment clearly showed the damages acid rain does to animals and plants living around us. It was hypothesized that when duckweed was placed in an environment with a lower pH than the duckweed will grow more slowly than if it were placed in a neutral pH of 7.
