Louis Pasteur’s Experiment
Like many other scientific breakthroughs, the
discovery of immunization happened by accident.
In 1880 Louis Pasteur was trying to protect chickens
from cholera. To study the disease, Pasteur and his
assistants gave injections of cholera bacteria to
several groups of chickens. The chickens usually
died from cholera after being injected with the
bacteria. However, one group of chickens survived.
Pasteur noticed that these chickens had been
injected with a six-week-old batch of cholera bacteria.
Pasteur’s assistants prepared new colonies of
cholera bacteria and injected these chickens a
second time. They also injected a group of chickens
that had not been previously injected. Pasteur was
surprised that the chickens that had been injected
previously with the old bacteria remained healthy,
while all the chickens in the second group became
sick and died.
This is how Pasteur came to discover that exposure
to weakened pathogens can provide immunity from
disease. The idea was later used to protect animals
from other serious diseases. Today immunizations
help protect people from many illnesses.

chickens

Boyle’s law gives the relationship
between the pressure and volume of
a gas if the temperature and mass of
the gas are held constant:• If the
volume of the gas is increased, the
pressure of the gas decreases.• If
the volume of the gas is decreased,
the pressure of the gas increases.

described above?
F Gas molecules travel longer distances at
greater speeds when the volume of the gas
is decreased.
G A gas is more likely to lose kinetic energy
when its volume is reduced.
H Gas molecules collide less frequently when
the volume of the gas is increased.
J A gas is more likely to increase in
momentum when its volume is increased.

the ocean.

101 In the past, people thought that life arose
spontaneously out of non-living material. This
belief was based partly on the observation that
vegetable broth swarmed with microorganisms
after sitting out for a few hours. Louis Pasteur
(1822–1895) believed spontaneous generation
was impossible. Which statement below would
best support Pasteur’s belief?
A Broth that was kept clean of airborne dust
particles shows no signs of life after many
days.

that those scientists made many
observations.
C If distilled water is substituted for the
broth, no microorganisms are revealed
after a few hours.
D Philosophical arguments offer no support
for spontaneous generation.
102 The smell of an ammonia solution used to clean
a floor can quickly be detected throughout a

Which statement best demonstrates the strength
of this theory?
A Scientists have observed tiny smoke
particles moved by unseen particles in a
rapid, irregular fashion.
B Scientists have unanimously agreed on this
theory since Thomas Graham’s
experiments in the 1820s.
C The possibility of another theory being
formed to explain the phenomenon as well
is very remote.
D Reason, as opposed to experimentation, is
superior to any explanation found through
chemical testing.

in stored apples

Ancient Greeks and Science
The ancient Greeks developed a set of
assumptions, based on observations, to
explain how the universe works. These
observations led the Greeks to believe that the
universe was composed of four elements:
earth, water, fire, and air. The “theory of natural
place” was based on their observations of
these four elements. The theory stated that
anything not in its natural place would move
toward its natural place as soon as an
opportunity arose. The theory of natural place
was the foundation for the modern
understanding of the elements. The following
chart describes some observations and
assumptions made by the ancient Greeks.
