Acid Rain and Seed Germination

Lab Summary

Use a pH sensor to determine the effect of acid rain on the germination of bean seeds.


Using the pH sensor and simulated rainwater from different sources, the students determine the effect of acid rain on the germination of bean seeds.
In this activity students will:

  • Become familiar with the way pH levels can vary within rainfalls or surface water
  • Measure the pH of different rain water samples
  • Gain skills and confidence in using a scientific measurement tool, the pH sensor, as well as the graphing capability of a computer to represent and analyze data

Sensors / Equipment Used:

PASPORT Chemistry Sensor


Allows students to measure Temperature, pH/ISE/ORP, Absolute Pressure & Voltage in one sensor. For use with PASPORT Interfaces.
