NAS 2 CHALLENGE EXAM (EXPECTED
QUESTIONS AND ANSWERS)
what is the purpose of the scientific method?
to ensure theory's are true by testing a hypothesis
What is the purpose of scientific method?
solve a problem or answer a question
"Test the hypothesis"
Scientific Method
It is a process that is used to answer questions about the
world
Steps of the Scientific Method
Identify problem, ( question)
Form Hypothesis,
Collect Data,
Analyze Data,
Form Conclusions
Identify the steps to the Scientific Method
observation, question, hypothesis, experiment, conclusion
The steps of the ______ are asking questions,
formulating hypotheses, gathering data, analyzing
data, and drawing conclusions. The method is widely
used in all the branches of science as it provides a
step-by-step guide of investigating questions and
answering a problem
scientific method
Independent variable
a variable that stands alone and isn't changed by the other
variables you are trying to measure, change or controlled
,example: age
The part of the experiment that is being changed or
manipulated to see if it has an effect.
Independent variable
the one variable that changes
Independent variable
a variable dependent on other factors, tested or
measured
example: test score - factors that go into a score you
receive on a test
dependent variable
dependent variable
the outcome; The part of the experiment that you
measure. It changes based on the effect of the
Independent variable.
the variable that remains constant
dependent variable
does not receive treatment and used to compare or
measure the other subjects
control group
Control group
Experimental group that does NOT get the independent
variable; used for comparison.
the thing that remains unchanged
control
experimental group
exposed to changes in independent variable.
the thing being tested on
experimental group
, anatomy
the study of bodily structures
branch of science concerned with bodily structure of
living organisms; structure
anatomy
Physiology
the study of functions of bodies
Structure determines function; function determines
structure - they're inseparable.
science dealing with the functions of living things or
their organs
physiology
six levels of organization
1.chemical
2.cellular
3. tissue
4. organ
5. organ system
6. organismic system
requirements for life
Cellular organization
Reproduction
Metabolism
Homeostasis
Heredity
Response to stimuli
Growth and development
Adaptation through evolution
water, food, oxygen, heat, pressure are __________
requirements of life
