Key Terms to Know
• Scientific inquiry – A process that includes the
different ways that scientists find out about
the natural world and try to explain what they
have observed.
• Hypothesis – One possible answer to a
scientific question.
• Variable – Something that can change in an
experiment.
Key Terms to Know – continued…
• Manipulated Variable or also called the
Independent Variable (IV) – The variable that
is changed on purpose during an experiment
to test a hypothesis.
• Responding Variable or also called the
Dependent Variable (DV) – The variable that
changes in response to changes in the
manipulated variable.
Key Terms to Know – continued…
• Controlled Experiment – An experiment in
which only one variable is manipulated.
• Operational Definition – A description of how
to measure a variable or define a term within
a controlled experiment.
• Data – Facts, figures, and other evidence that
a scientists collects through observing.
Key Terms to Know – continued…
• Communicating – The ways in which scientists
share ideas and experimental results with
other scientists.
• Scientific theory – A single explanation that
connects a large set of related observations or
results from experiments.
• Scientific law – A rule of nature that describes
what scientists suppose will happen every
time when conditions are the same.
Introduction 1. What does scientific inquiry refer
to?
Scientific theory refers to the diverse
ways in which scientist study the
natural world and propose
explanations based on the evidence
they gather.
Posing Questions
2. Is the following sentence true or false? Scientific
inquiry often begins with developing a
hypothesis. FALSE
3. Circle the letter of each sentence that is a
scientific question.
a. At which temperature does water boil?
b. When does the sun rise on April 3?
c. How can my team work better together?
d. Why does she like science more than he does?
Developing Hypotheses
4. A (n) hypothesis is a possible explanation for a
set of observations or answer to a scientific
question.
5. Is the following sentence true or false?
Scientists consider a hypothesis to be a fact.
_____true or false ___
6. What is a testable hypothesis? A hypothesis for
which researchers can carry out investigations
and gather evidence that will either support or
disprove the hypothesis.
Designing an Experiment
7. To test a hypothesis, a scientist designs a (n)
experiment.
GO TO THE NEXT PAGE FOR MATCHING TERMS->
Designing an Experiment
Match the term with its definition.
D 8. responding variable
A 9. operational variable
B 10. manipulated variable
E 11. controlled experiment
C 12. variable
13. Is the following sentence true or false? If you
did not control variables in an experiment, there
would be no way to know which variable explained
your results. TRUE
Collecting and Interpreting Data
14.The facts, figures, and other evidence
gathered through observations are called
data.
15.In carrying out a controlled experiment, what
does a data table help you do? A data table
provides you an organized way to collect
and record your observations.
Collecting and Interpreting Data
16.Circle the letter of each sentence that is true
about graphs.
a. A graph can reveal a trend in data.
b. Graphs help scientists interpret data.
c. Graphs are the only way to organize data.
d. A graph can reveal a pattern in data.
Drawing Conclusions
17.A (n) conclusion is a summary of what you
have learned from an experiment.
18. What do you ask yourself in drawing a
conclusion about an experiment?
Whether the data support the hypothesis.
The Nature of Inquiry
Complete the Nature of Inquiry diagram by filling in
the blanks.
The Nature of Inquiry
19.Pose Questions
20.Form a hypothesis
21.Draw conclusions
Design an experiment
Collect and interpret data
The Nature of Inquiry
22.Why is scientific inquiry a process with many
paths, not a rigid sequence of steps?
Different questions may require different
approaches to finding answers.
Communicating
23.In scientific inquiry, what is communicating?
The sharing of ideas and experimental findings
with other through writing and speaking.
24.Circle the letter of the sentence that explains
why scientists describe their research in full
when they communicate with other scientists.
B. Other scientists need to be able to repeat a
scientist’s experiments.
Scientific Theories and Laws
25.What is a scientific theory?
A well tested explanation for wide range of
observations or experimental results.
26.Is the following sentence true or false?
Future testing can prove a scientific theory to
be incorrect. TRUE
27.You can think of a (n) scientific law as a rule
of nature.
Scientific Theories and Laws
28.How is a scientific law unlike a scientific
theory? Unlike a scientific theory, a
scientific law describes an observed pattern
in nature without attempting to explain it.
