Acid rain experiment
Aim: to observe the effect of acid rain on plants
Materials:

  • 8 small potted plants of the same kind
  • white vinegar

  • measuring cups

  • teaspoon

  • distilled water

Method:
  1. Pour 41/2 teaspoons of vinegar into 2 cups of water, stir well.

  2. Put labels ‘water’ on 4 plants and ‘vinegar’ on the other 4 plants.

  3. Set the cups where they are not likely to be disturbed and where they will receive some daylight.

  4. Water the plants labeled ‘water’ with 1/8 cup of water daily.

  5. Water the plants labeled ‘vinegar’ with 1/8 cup dilute vinegar-water daily.

  6. Take photos, observe and record results.

The plants grown with water should grow faster than plants grown with acid water. Acid water, like acid rain, can directly damage plants and slow or stop new growth.

 

Results:

 Day 1
Both sets of plants limp from insufficient moisture

Day 2
‘water’ plants revived while ‘vinegar’ plants have become even more limp

Day 3
‘water’ continues to grow while one set of ‘vinegar’ plant dies and the other starts to wither

Day 4
‘vinegar’ plants are not dead, as can be seen with new growth, but are heavily withered and bleached. 'water' plants flourishing  and growing at a speedy rate.

Day 5
All colour starts to fade from ‘vinegar’ plants, still alive but on the brink of death. ‘water’ plants have further growth.
