Quiz One (NSC 131)
Science (5) - ANS --A way of knowing
-An approach to understanding the natural world
-Based on inquiry
-Process
-A search for explanations, information, and answers to specific questions
_______ and _______ are the two approaches that evolve critical thinking. - ANS --Discovery
-Hypothesis-driven
Discovery Science - ANS --Describes Nature
-Observe and measure
-Verifiable, replicable
Scientific method steps - ANS --Observe
-Question
-Hypothesis
-Prediction
-Experiment
Model - ANS --Test an experiment that isn't practical
-Simulates a long term event
-Ex: Weather, Traffic
Data/Datum - ANS --Collected information
-Often in numbers
-If data supports hypothesis, you accept it
-If data doesn't support hypothesis, you reject it
Laws in Science - ANS -Generalization that describes constant natural phenomenon for which
there is an incomplete scientific method
Laws - ANS --Observed to occur in every instance
-Unexplainable
Ex:Laws of Motion, Thermodynamics
Theories - ANS --Revolutionary ideas
-Tie together multiple observations that seemed unrelated
-Broad explanatory power
-Cover hard to test ideas
, -Never been disproved
-Accumulation of support
-Comprehensive, extensive, and varied evidence
Ex: Cell Theory, Big Bang Theory, Evolution
Experiments - ANS --Tests that can support/falsify a prediction
Variables - ANS --A characteristic or event that differs among groups
-Ex: Experimental group, Control group,
Independent, Dependent, Controlled
Experimental Group - ANS -Has a certain characteristic/receives particular treatment
Control Group - ANS -Identical to the experimental group but does not have certain
characteristic/receive particular treatment
Independent Variable - ANS --The variable changed
-Only one independent variable
Ex: amount of water
Dependent Variable - ANS --The variable measured
-Can be many dependent variables
Ex: Height in plants, Amount of seeds
Controlled Variables - ANS --Variable that doesn't change
Ex: Environment, time watered, amount of light
The larger the sample the more _______ the _______ gets. - ANS -Reliable, data
Sampling Error - ANS --Results
-Aren't Reliable due to sample size
-30+ samples is average
Probability - ANS -A measure of chance that a particular outcome will occur
Statistical Significance - ANS --Didn't occur by chance
-Repetitions increase significance
T or F: Science answers all questions - ANS -False; Can not answer all questions
What must all hypotheses do? - ANS -Be able to be disproved or it isn't valid
T or F: Science is Self-correcting and progressive - ANS -True
