Does ice )melt faster in an empty glass or in a glass full
of water?
Which topic would be appropriate for a controlled experiment? ( Correct

Determining how fast different chemical pollutants
dissolve in water
Which question requires a controlled experiment to answer? ( Correct
answers
type of rock

calcium?
Sir Isaac Newton discovered that the force of gravity between two masses
increases
the masses if increase, and decreases if the distance between the masses
increases. Nohave ever contradicted this relationship. Which type of
experiments
scientific
is statement
this? ( Correct answers )
Law
The well-accepted scientific explanation for many characteristics of Earth's
crustthe
that states
crust is broken into several large plates. These plates move
slowly over
mantle below thebecause of convection and other processes. Earthquakes and
are most common at places where the plates interact. Evidence
volcanoes
from physics,
chemistry, and geology supports this explanation. Which type of scientific
idea is this an example of? ( Correct answers )
explanation
Theory
A student proposes that sugar will dissolve faster in rubbing alcohol than in
water. The
student reasons that sugar and rubbing alcohol both contain carbon so
they will

relationships
individuals andamong

society.
GRADED
A+
, Theory ( Correct answers ) A hypothesis that has been tested with a
significant amount of data
Hypothesis ( Correct answers ) A testable prediction, often implied
by a theory
Observation ( Correct answers ) Information obtained through
the senses.
Why was the shrinking Earth idea replaced by the theory of plate
tectonics?
answers ) Plate
( Correct
tectonics explained observations about Earth that the
shrinking
idea couldEarthnot
explain.
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
Valles Marineris of on Mars, the longest known series of canyons in the solar
system. The
scientist found that Valles Marineris showed features found only in
locations
where major on Earth
tectonic plates divide. What would be the appropriate
scientists
response of to this information? ( Correct answers ) Carry out further
research
more to gain
understanding of possible plate tectonics
on Mars
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
are in lines that could correspond to past or present plate boundaries, but
seamounts
many are
aligned in not
this way. How should scientists appropriately respond to the idea
that some
new mechanism of forming the volcanoes is involved? ( Correct answers )
Carry research
more out to understand better how the seamounts form
For many decades, scientists thought they understood how ozone breaks
stratosphere,
down in the creating ozone holes. However, new data show
significantly
reaction rateslower
than can be explained by the long-held model. What is the
scientific approach for dealing with this contradiction? ( Correct answers )
appropriate
The existing
theory was changed to account for
new data
A woman does pushups by lowering her body to the floor using her
arms andagainst
pressing then the floor with her hands to push herself back up, as
shown

Two boxes sitting on the floor look identical, but one has more mass than
the other.
