You can build an agriculture working model that combines hydroponics, solar energy, greenhouse farming, and drip irrigation on one base.
Materials Needed:
Cardboard & Color Paper (for structure and decoration)
Plastic Bottles or Small Containers (for hydroponic system)
Small Tubes or Straws (for drip irrigation)
LED Light or Small Solar Panel (for solar energy simulation)
Transparent Plastic Sheet (for greenhouse effect)
Small Plants or Artificial Plants (for demonstration)
Water Pump (Optional) (for automatic water flow)
Glue, Scissors, and Tape
Steps to Build:
1. Base Setup (Common Foundation for All Systems)
- Use a cardboard sheet as the base.
- Divide it into four sections for hydroponics, solar, greenhouse, and drip irrigation.
2. Hydroponics System
Concept: Growing plants in nutrient-rich water without soil.
- Cut a plastic bottle or tray to make a water reservoir.
- Place small net cups or sponge pieces with plant roots inside the reservoir.
- Use a small tube or straw to circulate water.
3. Solar Energy System Concept: Using solar energy for sustainable farming.
- Place a small solar panel on the roof of the greenhouse or a stand.
- Connect it to an LED light to show how solar energy powers farming.
- Alternatively, use solar energy to power a water pump for drip irrigation.
4. Greenhouse Farming
Concept: Controlling temperature and humidity for plant growth.
- Build a mini greenhouse structure using cardboard for walls and a transparent plastic sheet for the roof.
- Place small plants inside to show how they grow in a controlled environment.
- You can also add cotton or small mist spray to represent humidity control.
5. Drip Irrigation System
Concept: Conserving water by providing slow and steady moisture to plant roots.
- Use small plastic tubes or straws to create a pipeline.
- Attach tiny holes in the tubes to allow water to drip slowly to plant roots.
- Connect it to a small water container or pump for demonstration.
How the Model Works:
The hydroponic system grows plants without soil.
The solar panel provides energy for the farm.
The greenhouse protects plants and controls temperature.
The drip irrigation system delivers water efficiently to the roots.
