1
A scientist proposes hypothesis about how a newly discovered virus affects humans. Other virus researchers would likely
design new experiments to test the proposed hypothesis
change the hypothesis to fit their own findings
assume that the hypothesis is true for all viruses
reject the hypothesis right away
2
The work of scientists usually begins with
creating experiments
careful observations
drawing conclusions
testing a hypothesis
3
A theory
is a problem to be solved
may be revised or replaced
is the opening statement of an experiment
is always true
4
Information gathered from observing a plant grow 3 cm over a two-week period is called
data
variables
hypothesis
inferences
5
During a controlled experiment, a scientist isolates and tests
a conclusion
a mass of information
a control group
a single variable
6
The basic unit of length in the metric system is the
meter
liter
gram
cup
7
Which of the following is NOT a goal of science?
to use derived explanations to make useful predictions
to establish a collection of unchanging truths
to explain events in the natural world
to investigate and understand the natural world
8
Scientists try to repeat each other's results. Which of the following should a scientist do to make it easier for this?
Not use a control to save time.
Skip peer-review so the results are available sooner.
Collect only one set of data
Use the metric system when communicating procedures and results.
9
How do scientific theories compare to hypotheses?
Theories unify a broad range of observations and hypotheses
Theories are the same as a hypotheses
Hypotheses combine the ideas of several theories to explain events
Hypotheses are the dominant view among scientists
10
A scientific hypothesis
is a proven fact with much evidence to support it
can be tested by experiments or observations
does not have to be tested to be accepted as correct
can be based on personal beliefs or opinions
11
A well tested explanation that explains a lot of observations is
a hypothesis
a controlled experiment
an inference
a theory
12

an analysis
a hypothesis
an experiment
14
