This model demonstrates how a greenhouse creates a controlled environment to help plants grow. It traps heat from sunlight using a transparent cover, maintaining a warm and moist atmosphere inside.
Greenhouses are used in agriculture to grow plants even in cold weather or poor soil conditions.
This DIY model shows the greenhouse effect, temperature control, and water retention — all essential for modern farming.
Materials Needed (Easily Available):
- Cardboard sheet (for base)
- Transparent plastic sheet / cling film / old plastic file (for covering)
- Small plastic or paper box (greenhouse frame)
- Straws or ice cream sticks (for greenhouse frame structure)
- Small toy plants / artificial plants / real seedlings (for display)
- LED bulb or torch (to show sunlight or internal heating)
- Thermometer (optional – to show temperature difference)
- Paints, glue, scissors, tape, scale
- Cotton or sponge (to simulate water/moisture)
- Marker pens and labels
How to Make It – Step-by-Step:
Step 1: Make the Base
Use a cardboard sheet as your base platform.
- Paint or cover with green paper to resemble farmland or soil.
Step 2: Build the Greenhouse Frame
- Use straws or ice cream sticks to make a cube-shaped frame (like a small hut).
- Glue or tape the joints to secure them.
- Leave one side open as a “door.”
Step 3: Cover with Transparent Plastic
- Wrap the greenhouse frame with transparent plastic or cling film.
- This simulates the glass walls of a real greenhouse.
- Make sure all sides except the door are sealed.
Step 4: Add Plants
- Place small artificial plants or real seedlings inside the greenhouse.
- Optionally, keep moist cotton or sponge to simulate watering.
Step 5: Light Source
- Place a small LED bulb or flashlight outside to show sunlight.
- You can even show how it heats up faster inside the greenhouse with a thermometer.
