Testing Rainwater pH | Science Fair Projects | STEM Projects
Have you ever wondered how the pH of rainwater changes in different places? Join us in this experiment to find out! Collect rainwater in your neighborhood and measure its pH with test strips.

Hypothesis

The hypothesis is that the pH of rainwater will differ from one place to another.

Method & Materials

You will collect rainwater in your neighborhood, measure its pH with test strips, and compare your findings with other students.
You will need pH test strips and a plastic 1-oz. cup for each student.

Results

The results of this experiment showed that the pH of rainwater does indeed differ from one place to another. One observation that stood out was that the pH of rainwater was higher in areas with more industrial activity.

Why do this project?

This science project is interesting and unique because it allows students to explore the environment around them and gain a better understanding of how different factors can affect the pH of rainwater.

Also Consider

Experiment variations to consider include testing the pH of a river and other water sources in the city.
