C165 Test Review Questions with Verified
Correct Answers
A scientist displays a poster of the solar system on their wall. What type of model is
this?
Conceptual
A 5th-grader builds a small-scale volcano for a science fair project. They use baking
soda and vinegar to make the volcano erupt. What type of model is this?
Physical
A physicist graphs the results of their experiment on a scatterplot. What type of model
is this?
Mathematical
Albert Einstein developed a detailed and far-reaching explanation of gravity being
caused by the bending of space and time by the presence of matter. This explanation
made far-reaching predictions of phenomena that were later confirmed, such as the
bending of the path of light when the path passed close by a star. It is currently the basis
for many phenomena observed in astronomy. Einstein's explanation would be MOST
accurately described as a
Theory
Which of these describes a statement that has usually NOT yet been tested?
Hypothesis
"Mass and acceleration are inversely related." What classification best describes this
statement?
, Law
A ten-year-old budding scientist studies how ants organize their colony in a glass
terrarium that she keeps in her room. What type of experiment is the child performing?
Laboratory-based observational study
A geologist hikes a portion of the Appalachian Trail and notes the angles of the
sedimentary rocks. What type of experiment is the geologist performing?
Field observational study
In a controlled experiment, which variable is changed by the scientist at the beginning?
Independent Variable
A jogger decides to test how the speed of the music they listen to will influence the time
it takes them to run a mile. Over the course of several days, they run the mile ten
different times along the same route, recording the time it takes to complete this. On
each run, they listen to music with different beats per minute. For example, on the first
run, the jogger listened to only music with a speed of 155 bpm. What is the dependent
variable in this experiment?
Time to complete the mile (minutes)
