Conserve Natural India

Sustainable Development in Northern India

Sunny morning in Shanney

It was a perfect day for solar cooker experiment. So we gathered some kids from the community and a few interns at 10 am in the Shanny community (Naddi).

The idea was to make a solar cooker using a pizza box and explain some concepts related to solar energy.

Concepts explained:

  • What is solar energy?
  • What is the purpose of using black paint and aluminium paper? Absorption and reflection.
  • What is the purpose of using transparent paper? Insulation.
  • Sun path and cardinal points.
  • Orientation and inclination.

We moved from Shanny community to Mr B’s (Chief Project director of EduCARE India) house where I had prepared all the materials and one “solar pizza cooker” prototype a week in advance.

We split in 3 teams; Leopards, Tigers and Beandriya (female monkey in Hindi). Each team had one or more interns who were helping them with the assembly.

After about 20 minutes of construction Beandriya team finished first, with a very nice and personalized model, Tigers were second and Leopards third.

While asking few questions it turned out that they were well aware of the sun path, sunset and sunrise. However, naming the cardinal points became a very confusing task. After 5 minutes of pointing South, saying East a variety of cardinal points came into existence. I tried to make clear how to point South and locate East and West. I hope they remember for future reference.

To explain absorption and reflection I left 2 different containers filled with water in the sun. One painted black and the other wrapped in aluminium.

Kids (and some interns…) found the result of the experiment very interesting. Which container would have the water with the higher temperature?

Finally the three solar cookers were ready to be tested.
