C165 Study Guide Questions with Verified
Correct Answers
A mathematical model is used to predict the trajectory of a bullet fired from a gun.
Which discipline of physical science is used to develop this model?
Physics
An environmental scientist monitors pollutants in a lake. Which two disciplines of
physical science does this scientist use?
Chemistry and Earth science
Which study involves both Earth science and physics?
Calculating how much energy is associated with a hurricane
Which question could be answered with a controlled experiment?
Does ice melt faster in an empty glass or in a glass full of water?
Which topic would be appropriate for a controlled experiment?
Determining how fast different chemical pollutants dissolve in water
Which question requires a controlled experiment to answer?
Which type of rock contains the most calcium?
Sir Isaac Newton discovered that the force of gravity between two masses increases if
the masses increase, and decreases if the distance between the masses increases. No
experiments have ever contradicted this relationship. Which type of scientific statement
is this?
Law
, The well-accepted scientific explanation for many characteristics of Earth's crust states
that the crust is broken into several large plates. These plates move slowly over the
mantle below because of convection and other processes. Earthquakes and volcanoes
are most common at places where the plates interact. Evidence from physics, chemistry,
and geology supports this explanation. Which type of scientific idea is this explanation
an example of?
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 mix
more easily. Which type of scientific idea is the student's proposal an example of?
Hypothesis
Law
A body of enforceable rules governing relationships among individuals and between
individuals and their society.
Theory
A hypothesis that has been tested with a significant amount of data
Hypothesis
A testable prediction, often implied by a theory
Observation
Information obtained through the senses.
Why was the shrinking Earth idea replaced by the theory of plate tectonics?
