Investigating the Effects of Acid Rain on Plants


Simulate acid rain and observe its impact on plant growth and health.


  • Potted plants (same species)
  • Vinegar
  • Water
  • pH strips
  • Measuring cup
  • Notebook for observations


  1. Prepare a solution of water and vinegar to simulate acid rain with a pH similar to real acid rain.
  2. Water one group of plants with the acidic solution and another group with regular water.
  3. Measure the pH of the solutions using pH strips.
  4. Water the plants at regular intervals with the respective solutions.
  5. Observe and record the growth, leaf color, and overall health of each plant weekly in your notebook.
  6. Compare the growth and health of plants exposed to acid rain with those watered with regular water.
  7. Analyze the impact of acid rain on plant growth and document your findings.
