how to make working model of acid rain

“This is a working model of acid rain. Factories release harmful gases like sulfur dioxide and nitrogen oxides into the air.


These gases rise into the atmosphere and mix with water vapor in the clouds to form sulfuric and nitric acid.
When it rains, this mixture falls to the ground as acid rain.
Acid rain damages forests, pollutes rivers and lakes, and even erodes buildings and monuments.
This model shows how human activities contribute to acid rain and how it affects the environment.

Materials Required:

  • Cardboard base (for landscape)
  • Thermocol or cardboard mountains
  • Small toy trees / green sponge / green color paper (for forests)
  • Factory model (use small boxes, straws/pipes as chimneys)
  • Cotton or sponge (for clouds)
  • Blue cellophane or colored paper (to show water/river)
  • Markers / sketch pens
  • Color paper (grey, black for pollution effect)
  • Glue, scissors, tape
  • Optional: LED light and spray bottle (for rain effect)

Video Step-by-Step Model Making:

Step 1: Prepare the Base

  • Take a large cardboard as the base.
  • Mark different zones: Factory area, Mountains, Forest, River.

Step 2: Make the Factory

  • Use small boxes to make factories.
  • Add chimneys using straws or paper rolls.
  • Show smoke with cotton colored grey or black.

Step 3: Make the Mountains

  • Use thermocol cut in triangle shape or folded cardboard.
  • Paint brown and white (for snow top).

Step 4: Forest and Water

  • Stick green sponge or toy trees for forest.
  • Show river using blue paper or foil.

Step 5: Clouds and Rain

  • Use cotton for clouds.
  • Use a spray bottle filled with water (add vinegar to simulate acidic nature) and label it “Acid Rain”.
  • Optionally, use LED lights inside clouds for effect.
