Introduction: Getting to know CO2 levels; Seeing the invisible all around us.
Observing how much higher the CO2 is in what you breath out
Compared to what we breath in. Experience the dramatic difference.
People of all ages become aware of levels, comfortable with ppm
Comparing amounts of carbon dioxide released by different human activity.
by various human activity -- one kilogram of carbon dioxide is produced by:
24 hours of breathing by an adult (2 days by a small child). NOT a large amount.
Easily absorbed by a large tree, Earth's natural cycles can handle with no problem.
By comparison, the same amount is released in 3 minutes by one car
[if a 30mpg vehicle at 60 miles per hour].
The burning of jet fuel to keep one passenger aloft in a commercial airliner
produces the same 1 kilogram of carbon dioxide in 18 seconds.
What we do, as individuals and as a society, makes a big difference in emissions.
More in depth labs experiment with emissions by various transportion
and energy technologies.
Characteristics of CO2 molecules-heat trapping gas, compared to N2 & O2
At the American Association for the Advancement of Science conference:
NASA/JPL Climate Science Day
Over a thousand high school students take part in climate science labs
Lab Experiments -- examples:
Take samples of CO2 produced by cars. Tailpipe emissions. Percentage C02.
Calculate volume and rate at different fuel consumption.
Measuring the CO2 produced by burning of fuel. Starting with a candle.
Calculate amount released by burning of a liter (or gallon) of gasoline.
