Creating a model for a science exhibition on air, water, land, and noise pollution using cardboard is a great idea!
Here’s a step-by-step guide for each aspect:
Materials Needed:
- Cardboard sheets
- Acrylic paint
- Paintbrushes
- Glue
- Scissors
- Markers
- Small plastic containers (for water pollution)
- Miniature toy cars, trees, and other elements (for land pollution)
- Small cardboard boxes (for buildings, houses, and factories)
- Small LED lights or colored paper (for noise pollution)
Air Pollution Model:
- Row Houses:
- Cut out rectangular shapes for row houses from cardboard.
- Paint them in various colors to represent different houses.
- Attach small chimneys made of rolled-up cardboard to represent air pollution from domestic sources.
- Vehicles:
- Create miniature cardboard vehicles like cars and buses.
- Paint them and attach them to the model roads.
- Consider making a small traffic jam to emphasize the pollution caused by vehicles.
Land Pollution Model:
- Agriculture Field and Dumping:
- Create a cardboard base to represent the land.
- Use small cardboard boxes as houses or factories, and place them on the land.
- Represent agriculture by adding tiny cardboard crops.
- Show dumping by placing miniature trash bins or piles of cardboard trash.
Water Pollution Model:
- House and Factory Outputs:
- Make small cardboard houses and factories.
- Attach plastic containers near them to represent water bodies.
- Paint the containers blue for water.
- Pour a small amount of water into the containers to represent the water bodies.
- Add drops of paint or small bits of colored paper to represent pollutants flowing into the water.
Noise Pollution Model:
- Loud Speaker and Sirens:
- Create miniature microphones using small cardboard pieces.
- Paint them black and attach them to represent sound recording equipment.
- Use small LED lights or colored paper to create sirens or loudspeakers.
- You can add a switch to simulate the activation of noise sources.
