Crawford County's Carbon Footprint
Posted: October 11, 2010
A "carbon footprint" is a measure of the impact our activities have on the environment, and in particular climate change. It relates to the amount of greenhouse gases produced in our day-to-day lives through burning fuels for electricity, heating and transportation etc.
The experiment that we conducted involved a glass of water colored with a special chemical that turned the water blue; we then covered the water with a piece of plastic and blew into the water with a straw. When the CO2 from a person's breath entered the water most of it bubbled and left the water, but some it stayed and reacted with the chemical already in the water turning the water yellow and green. this showed that CO2 does leave traces in water.
We also calculated our own effects on the environment. We calculated the number of miles we drive each year (approximately), the number of miles we flew, the amount of electricity we use each month, and some other variables to determine roughly how much carbon we put into the atmosphere annually.
The results were amazing. Some youth are very eco in-tune and leave barely a trace while others are considered carbon challengers and were seeking ways to conserve and improve their standings.
