Did You Know?
The world’s largest solar cooking system in India can cook 50,000 meals per day!
Solar ovens can reach temperatures of 150-200°C, enough to bake bread and cook rice!
What is a Solar Oven?
A solar oven is a device that traps sunlight and converts it into heat to cook food. It works by reflecting, absorbing, and retaining heat using mirrors, glass, and insulating materials.
Advantages of a Solar Cooker:
Uses renewable energy (free sunlight!)
Eco-friendly – no fuel or electricity required
Safe and easy to use for kids
Can be used in remote areas where fuel is scarce
Materials Required
To build a simple solar oven, gather these materials:
Cardboard box (for the structure)
Aluminum foil (to reflect sunlight)
Plastic wrap or glass sheet (to trap heat)
Black construction paper (to absorb heat)
Tape and glue (for assembly)
Thermometer (to measure heat inside the oven)
Arduino Kit & Temperature Sensor (optional for advanced experiment)

Step-by-Step Guide: How to Make a Solar Oven
1. Prepare the Box
Take a cardboard box and cut a flap in the lid.
Cover the inner side of the flap with aluminum foil.
2. Line the Box
Cover the inside of the box with black construction paper.
Seal the opening with plastic wrap to create a greenhouse effect.
3. Set Up the Reflector
Adjust the foil-covered flap to reflect sunlight into the box.
Place food inside and position the oven in direct sunlight.
4. Measure the Heat
Use a thermometer to track the temperature inside the solar oven.
Observe how long it takes to cook simple food items like s’mores or toast!
The Science Behind a Solar Cooker
A solar cooker diagram helps visualize how sunlight is captured and converted into heat. By reflecting and trapping solar energy, a solar oven efficiently cooks food.
A Box-Type Solar Cooker works using three main principles:
Reflection: The aluminum foil redirects sunlight into the box.
Absorption: Black paper absorbs heat to warm the food.
Insulation: The plastic wrap traps heat inside, creating a mini greenhouse effect.
