In this experiment, the goal was to find the correlation between soil pH and precipitation. This is in order to show the importance of preserving the environment because global warming is causing increased precipitation. This increase in precipitation causes soil to acidify, hurting the plants. It was hypothesized that an increase in precipitation would decrease the pH because the precipitation replaces basic ions with hydrogen ions that increase acidity. The findings showed that soil pH does decrease with the increase of precipitation. We used provided materials such as pH test strips, laser thermometer, test tubes, and other lab equipment. In conclusion, the effect of precipitation is apparent in relation to soil pH.
