QUESTION: A student proposes that sugar will dissolve faster in rubbing alcohol than water. The
student reasons that sugar and rubbing alcohol both contain carbon so they will mix more
easily. Which type of scientific idea is the student's proposal an example of?
a) Theory
b) Observation
c) Law
d) Hypothesis - ANSWER-d) Hypothesis
QUESTION: Why was the shrinking Earth idea replaced by the theory of plate tectonics?
a) Plate tectonics explained observations about Earth that the shrinking Earth could not explain.
b) Many well-known geologists were involved in proposing plate tectonics.
c) Geologists voted on which theory to accept, and chose plate tectonics.
d) Plate tectonics was a new theory, which made it more reliable. - ANSWER-a) Plate tectonics
explained observations about Earth that the shrinking Earth could not explain.
QUESTION: Astronomers have long accepted that plate tectonics exists nowhere in our solar
system except on Earth. In 2011, a scientist analyzed 100 NASA-space mission photographs of
Valles Marineris on Mars, the longest known series of canyons in the solar system. The scientist
1
,Page 2 of 166
found that Valles Marineris showed features found only in locations on Earth where major
tectonic plates divide.
What would be the appropriate response of scientists to this information?
a) Hold public debates among scientists and then vote whether plate tectonics occurs on Mars
b) Decide whether to accept plate tectonics on Mars based on the reputation of scientist
involved
c) Carry out further research to gain more understanding of possible plate tectonics on Mars
d) Reject plate tectonics on Mars as the explanation because it contradicts accepted science -
ANSWER-c) Carry out further research to gain more understanding of possible plate tectonics
on Mars
QUESTION: According to the theory of plate tectonics, volcanoes are especially likely to form
along plate boundaries because of rising magma. New satellite data mapping the ocean floor
reveals thousands of seamounts, which are small volcanoes. Some of the seamounts are in lines
that could correspond to past or present plate boundaries, but many are not aligned in this
way.
How should scientists appropriately respond to the idea that some new mechanism of forming
the volcanoes is involved?
a) Reject it because it contradicts the theory of plate tectonics
b) Accept it if the person proposing it is a credible expert on plate tectonics.
c) Carry out more research to understand better how the seamounts form
d) Stage public debates to get a consensus on how the seamounts form - ANSWER-c) Carry out
more research to understand better how the seamounts form

QUESTION: For many decades, scientists thought they understood how ozone breaks down in
the stratosphere, creating ozone holes. However, new data show significantly lower reaction
rates than can be explained by the long-held model.
What is the appropriate scientific approach for dealing with this contradiction?
a) Conduct additional experiments to confirm the new data
b) Ignore the new data because it contradicts the accepted model
c) Ask the general public to vote on which data are correct
d) Accept whichever data the most famous scientists support - ANSWER-a) Conduct additional
experiments to confirm the new data
QUESTION: For almost 1500 years most scientists in Europe accepted Ptolemy's geocentric
planetary model that suggested the sun revolved around Earth. By the eighteenth century,
most scientists supported a heliocentric model that suggests that Earth revolves around the
sun.
What is an appropriate scientific basis for this change in view?
a) The most prominent scientist that supported the geocentric model died
b) The existing theory was changed to account for new data
c) The old theory was voted down by a scientific council
d) The heliocentric model was supported by a popular scientist - ANSWER-b) The existing theory
was changed to account for new data
A mathematical model is used to predict the trajectory of a bullet fired from a gun.
