WGU Integrated Natural Science Exam
Questions and Answers
Describe the scientific method - ANSWER-Question, Hypothesis, investigation,
observations, conclusion, reproducibility
Definition of each component of the scientific method - ANSWER-Question- what do
you want to know, Hypothesis- production about what will happen, Investigation- a way
to test the hypothesis, Observation- info gathered, Conclusion- results, Reproducibility-
can the results be replicated.
Controlled experiment - ANSWER-An experiment in which one condition is allowed to
vary and all others are kept constant
Independent Variable - ANSWER-What we are changing on purpose
Dependent Variable - ANSWER-Its what depends on the independant variable
Controlled Variable - ANSWER-All the conditions except the independent variable have
to be kept exactly the same
Field Study - ANSWER-Investigations in the real world not in a lab
Computational Models - ANSWER-And representation of the natural world developed
mathematically on the computer
Falsifiablity - ANSWER-The hypothesis has to be able to be proven wrong
Fact - ANSWER-Anyone who is able to observe the phenomenon will observe the same
thing
Law - ANSWER-Supported by all available evidence
Theory - ANSWER-Broad synthesis of info that explains all of our available
observations
How can evidence be used to either support or refute a claim - ANSWER-Expected
results= actual results- supports claim
Expected results do not equal actual results- refutes claim
Systems approach - ANSWER-Stufy the system as a while and the interactions
between its components.
