1
What does a horizontal line on a line graph represent?
it is increasing
it is decreasing
no change over time
the data is inconclusive
2
Which is the LEAST LIKELY to provide empirical evidence supporting a scientific theory?
measurements
repeatable results
consistent observations
popular opinion
3
What is a scientific explanation of related observations based on ideas that have been repeatedly tested and true.
scientific theory
skepticism
conclusion
scientific law
4
What type of scientist is MOST LIKELY to use a microscope to observe the structures that make up living things?
physics
chemistry
biology
geology
5
Which of the following is MOST LIKELY to increase the confidence of the scientific community in the results of an exp.
scientists who replicate the experiment obtain different results
the experiment is repeated many times with same results
the company that paid for the experiment publishes the results
scientists who replicate the experiment change a variable
6
An experiment tests how the amount of light (h) affects the growth of bean plants (cm). What is the x axis and y axis?
x = bean plant, y = amount of light per day (h)
x = amount of light per day (h), y = height after 4 weeks (cm)
x = amount of light per day (h), y = bean plant
x = height after 4 weeks (cm), y = amount of light per day (h)
7
Scientific explanations are based on which of the following?
hypotheses
hunches
predictions
empirical evidence
8
Which of these questions can BEST be answered by a field study?
how dense is the wood in an oak tree
who owns the nearby forest
will squirrels have healthier offspring if their diet changes
which types of trees in a nearby forest are growing fastest
9
A geologist is MORE LIKELY to work in a lab than in the field when
collecting rock samples
testing rock samples for their reactivity with acid
measuring the thickness of layers in a boulder
collecting water samples
10
Which is most likely to involve experimentation in addition to observation?
determining the effect of temperature on cell division in bacteria
determining population size of deer in a forest
calculating the density of different types of wood
determining the chemical composition of a substance
11
A scientist conducts an experiment to find conflicting data with a theory widely accepted. What should the scientist do
the scientist should record the results and repeat the experiment
the scientist should discard the findings
the scientist should publish the results
the scientist should communicate the results
12
Which is an example of a good scientific question?
Which kind of animal makes a better pet-cats or birds?
How should a teacher grade students in his class?

13
What is a characteristic of ALL models?
they use data to make predictions
they represent things that are too large to be observed directly
they have limitations as well as benefits
they are built to scale
14
New evidence shows an accepted scientific theory to be wrong. Which is most likely to happen as a result?
the accepted theory will not be affected in any way
new experiments will be done to support the accepted theory
the accepted theory will be revised or replaced
reports of the new evidence will be changed to support the accepted theory
15
A student wants to know if a type of soil used will affect the growth of a pea plant. What is the dependent variable?
type of soil
amount of water
number of plants
height of the plant
16
A student does an exp. to test how temp. affects how high a tennis ball bounces. What is the independent variable?
average bounce height of all three balls
temperature of each ball
type of ball used in the experiment
bounce height for each ball
17
Two scientists conduct the same experiment with different results. What is the best plan to resolve the difference?
consider the educational backgrounds of the scientists
have other scientists replicate the experiment to validate the results
accept the results of the scientist who published the results first
accept the results that best support the current theory
18
Which of the following is an example of repetition in science?
a scientist designs an experiment that contains multiple trials

procedure
hypothesis
question
20
Why do all scientific models have limitations?
it is never EXACTLY the same as what it represents
scientific models have no limitations
it is exactly the same as what it represents
scientific models are manmade
