Creating a rainwater harvesting model using cardboard and waste materials is an excellent way to demonstrate sustainable practices and the importance of water conservation. Here’s a step-by-step guide to make this model:
Materials Needed:
- Cardboard (for the base, house, and tank)
- Waste materials (e.g., plastic bottles, straws, etc.)
- Color paper (for decoration)
- Plastic tray (for the agriculture field)
- Small plants or artificial plants
- Plastic tubing or straws (for the water pipes)
- Small water pump (optional, if you want to show the working model)
- 9V battery (if using a water pump)
- Scissors or craft knife
- Glue or hot glue gun
- Markers or pens
- Ruler

1. Prepare the Base and Structure
- Base Preparation:
- Cut a large rectangular piece of cardboard to serve as the base.
- Cover the base with green or brown color paper to represent the ground.
- House Construction:
- Construct a small house using cardboard. Cut out pieces for the walls, roof, and base.
- Assemble the house and cover it with color paper for a neat finish.
- Create a slanted roof to represent the water collection area.
2. Create the Rainwater Collection System
- Roof to Tank System:
- Cut a piece of plastic tubing or straws to represent the gutter system that will collect rainwater from the roof.
- Attach the tubing to the edge of the roof, ensuring it leads down to the side of the house.
- Water Tank:
- Create a water tank using a small plastic bottle or a cardboard box covered with color paper.
- Place the tank on the ground next to the house and connect the tubing from the roof to the tank.
3. Set Up the Agriculture Field
- Agriculture Field:
- Place a plastic tray next to the house to represent the agriculture field.
- Fill the tray with soil or artificial plants to simulate a field.
- Water Pump System (Optional):
- If using a small water pump, connect the pump to the water tank using plastic tubing.
- Connect the other end of the pump to the agriculture field tray.
- Use a 9V battery to power the pump and demonstrate the water flow from the tank to the field.
4. Assemble the Model
- Attach All Parts:
- Secure the house, water tank, and agriculture field to the base using glue.
- Ensure all tubing connections are secure and properly positioned.
- Add Details:
- Use markers to draw windows, doors, and other details on the house.
- Add small plants or artificial plants to the agriculture field for a realistic look.
5. Label and Decorate
- Label the Parts:
- Use markers or printed labels to mark different parts of the model, such as the house, roof, gutter, water tank, and agriculture field.
- Decorate the Model:
- Add color paper and other decorative elements to make the model visually appealing.
- Ensure the model is neat and clearly shows the rainwater harvesting process.
Final Touches:
- Interactive Elements:
- Demonstrate how rainwater flows from the roof to the tank and then to the agriculture field.
- If using a pump, show the water being pumped from the tank to the field.
By following these steps, you can create an effective and interactive rainwater harvesting model using cardboard and waste materials.
