“This is a working model of a Geothermal Energy Power Plant.Water is pumped underground where Earth’s heat turns it into steam.This steam rises through pipes, rotates a turbine, and generates electricity.
The electricity is transmitted through power lines to homes and factories.
Geothermal energy is a renewable, clean, and sustainable power source.”
Video Step-by-Step Model Instructions:
Step 1: Create Earth’s Layers
- Take a large cardboard box and place it horizontally.
- Cut one long side open to reveal the inside.
- Draw or paste colored layers inside the box to represent:
- Crust (brown),
- Mantle (red/orange),
- Core (yellow/glowing effect).
Step 2: Add Geothermal Pipes
- Insert 2-3 plastic pipes/straws from the top of the box going down to the hot core layer.
- Label one as Injection Well (cold water in), another as Production Well (steam out).
Step 3: Build the Turbine System
- On top of the box, build a small power station building with cardboard.
- Inside it, fix a plastic fan blade (turbine).
- Connect the steam outlet pipe to blow air (or syringe push) to rotate the turbine.
- Optional: Attach a DC motor behind the fan blade to light up an LED when spinning.
Step 4: Add Cooling Tower & Condenser
- Beside the turbine house, create a cooling tower using a paper cone.
- Add a pipe from turbine to cooling tower.
- Use cotton to show steam flow (visual effect).
Step 5: Create Power Transmission
- Add 3–4 power poles using skewers or straws.
- Use thread/wire as transmission lines.
- Connect the wires to a cardboard house to show power is delivered to consumers.
Step 6: Decoration & Labeling
- Paint the Earth’s layers, steam pipes, and top structures.
- Label clearly:
- “Geothermal Reservoir”
- “Injection Well”
- “Production Well”
- “Turbine”
- “Generator”
- “Cooling Tower”
- “Power Lines”
- “Home/Factory”
