Causing Rapid Climate Change Worksheet
The major component of any fossil fuel is
carbon. It forms seventy-five percent of methane, the major component of
high-grade natural gas. Carbon forms eighty-four percent of octane, which
typifies most gasolines, and it forms eighty percent of good anthracite coal.
Now here’s the catch. Since each carbon
atom joins with two heavier oxygen atoms, CO2 molecules are much
heavier than the carbon in fuels. Each pound of fuel yields almost three pounds
of CO2. That takes some digesting. Our first reaction is, “It’s
only a gas; it surely can’t amount to much.” But each gallon of gasoline
produces twenty pounds of carbon dioxide.
Our consumption of fossil fuels has now
caused the CO2 content of Earth’s air to be higher than it would normally
be. It’s certainly impacting our climates. How much is subject to a pretty
fierce debate, but global temperatures are definitely on the rise. While better
analysts than I try to determine exactly what part of the rise comes from CO2
greenhouse effects, we’d be crazy not to look for ways of reducing the CO2
in our air.
Your CO2 “footprint” is
basically a measurement of how much carbon dioxide is emitted into the
atmosphere as a result of your individual actions. Transportation choices are
just one component of a CO2 footprint – but can often be the most
significant. How big is yourtransportation footprint? And how
does it compare with that of your classmates? Through this activity you will
calculate your transportation CO2footprint for one trip
remembering that as a rough estimate, the burning of one gallon of gasoline produces
about 20lbs of CO2.
How to Calculate
Your Car’s Miles Per Gallon (MPG) Yield
You
must use this method and not just guess a value or use the value that the
manufacture or a web site gives. We want
to see what you car is actually getting with your driving.
1. Fill up your car’s gas
tank all the way (till the pump clicks off).
Before you leave the gas station write down the odometer mileage shown
in your vehicle.
2. Record the odometer
mileage reading for your car on the worksheet.
3. Drive your car as you
normally would, and let your gas tank deplete to at least a half of a tank.
(The lower you let your tank go, the better average rating you will get, but
don’t run out of gas!)
4. Get to the gas station
and fill your tank again (once more wait for the pump to click off).
5. Get a receipt, as this
will show the amount of gas in gallons that you pumped. Note the mileage on your odometer.
6. Record the amount of gas
it took to refill the tank on the worksheet.
7. Record the new odometer
mileage on the worksheet.
8. Calculate the miles
traveled by subtracting the first odometer reading from the second reading.
9. Divide the miles traveled
by the amount of gallons it took to refill the tank. The result will be your
car’s average Miles Per Gallon yield for that driving period.
10. Calculate the information
required and post your results to the Q&A forum on the class web site by Friday.
11. Complete the work sheet
and upload this document by the assignment due date.
Note
that the syllabus includes a vehicle to use so that you may complete the
worksheet assignments such as this one.
If you do not have your own car then arrange to collect the data from
one of your acquaintances or family members who do have a vehicle.
You must post your values
for table rows A, B, G and Question 4 to the Q&A from by noon on Friday.
