                                 MAIN HYPOTHESES
        Matter or Energy                              Reasoning Skills
                                  Students use energy as a convenient "fudge factor"
                                  when they either can't or don't see the necessity of
              Energy              tracing matter.
                                  Students fail to note energy loss during carbon
                                  transformation processes (2nd law of
              Energy              thermodynamics?).
                    Students have difficulty tracing matter from solids to
                    gasses and gases to solids. Students see an overly
                    simplified gas-gas cycle and an overly simplified solid-
     Matter         solid cycle.

                    Students who can trace matter into and out of an
                    organism may still not have an understanding of how
     Matter         matter is used/partitioned once in an organism.
                    Students who do not have an atomic-molecular
                    understanding of processes will not be able to trace
     Matter         matter across scales or across processes

                    Students do not recognize that processes happening at
                    larger scales are aggregate properties of the same
Matter and Energy   process happening at a smaller scale.
                    Students lack an understanding of quantification of
                    matter, especially small masses (e.g. mass of carbon
                    atom) and large masses (e.g. gigatons of carbon dioxide
     Matter         in the atmosphere).


                    Associated Misconceptions (Incomplete List)
                    Some students think atoms can become other atoms
     Matter         (e.g. carbon can become oxygen)
                    Some students think that matter can be transformed to
Matter and Energy   energy and vice versa
     Matter         Students think plants get carbon from the soil
                    Students don't conserve matter, assuming it can
     Matter         disappear

Explain why the use of biofuels instead of fossil fuels is a proposed strategy to slow the
rate of global climate change. Use as much detail in your answer as you can.

Scientists believe that the average temperature of the earth’s atmosphere has been
increasing
during the past 100 years. What is the major cause of this?
A) More heat is released from vehicles and factories into the atmosphere.
B) More particulate pollution (smog) is in the atmosphere.
C) More carbon dioxide is in the atmosphere.
D) Deterioration of the ozone layer
E) None of these causes global warming.

One liquid biofuel often used as a transportation fuel is ethanol (C2H5OH). Decide whether each of
the following statements is true (T) or false (F) about what happens to the atoms in a molecule of
ethanol when it burns.

T F Some of the atoms in the ethanol are incorporated into carbon dioxide in the air.
T F Some of the atoms in the ethanol are incorporated into air pollutants such as ozone or nitric
oxide.
T F Some of the atoms in the ethanol are converted into energy that moves the car.
T F Some of the atoms in the ethanol are burned up and disappear.
T F Some of the atoms in the ethanol are converted into heat.
T F Some of the atoms in the ethanol are incorporated into water vapor in the atmosphere.

On March 10, 2004, National Public Radio reported that “forests in a remote part of
the Amazon
are suddenly growing like teenagers in a growth spurt.” Though, the radio report
added, “This
shouldn't be happening in old, mature forests.” Scientists have speculated that our
actions may
have caused this phenomenon. What do you think could be the scientific basis
behind such a
speculation?
