Imagine that you have a ten year old niece/nephew who has just begun 

to hear about climate change in the current events part of their class 

in fifth grade.  However, s/he doesn’t really understand the concept of 

the Earth’s heating and cooling.  Write one page (paragraph format) 

about the relationship between the “Greenhouse Effect and 

Greenhouse Gases” that you could use as notes for explaining the 

concept to your niece/nephew.
