Introduction
Discuss “What is a actual greenhouse and science behind it”
Pre-Requisites:
pollution, air pollution, emission of gases on burning
Activity:
Observe how radiation gets trapped in a greenhouse and increases temperature, Make a table of earth’s temperature from fast 50 years for every 5 years and observe how it is rising, Make a list of measure you think your family can take to save Earth from global warming
Real Life Question:
“What happens in a greenhouse?”, “What greenhouse gases come out from our homes?”
