The Impact of Acid Rain on Plant Growth




Investigate how acid rain affects plant growth.


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


  1. Prepare a solution of vinegar and water to simulate acid rain with a pH similar to 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. Measure the growth of each plant weekly using a measuring tape or ruler.
  6. Record observations, including plant height, leaf color, and overall health in the notebook.
  7. Compare the growth and health of plants exposed to acid rain with those watered with regular water.
  8. Draw conclusions about the impact of acid rain on plant growth.
