science test Flashcards
science
producing knowledge based on observations (science is the calmative body of knoledge produced by many scientist)
empiricism (Basic principles of Science)
Observations of real phenomena that can help us understand natural processes
Uniformitarianism
Natural forces at work today are the same in that worked in the past
Parsimony
The simpler of two explanations
Uncertianty
Unsure about something
Repeatability
inquires should be reproducible (I should be able to reproduce a scientist experiment and get the same results )
Proof is elusive
New evidence can always improve scientific knowledge
Testable question
A question that is retestable by experiments or observation with some form of evidence.
why is being skeptical good for scientist
Scientist are skeptical and this is good because it can help ensure that the theory they produce is backed by evidence.
Why do scientist need to reproduce their results over and over again?
To ensure there first result wasn’t a fluke and ensure that results are consistent
dectuctive reasoning
deductive reasoning is the logical reasoning from already known facts
inductive reasoning
Inductive reasoning is taking observations into account and producing a genral rule
steps to scientific method
identify problem
create hypothesis
develop a procedure
experiment
conclusion
what is the scientific theory
when a theory has been supported by a large number of scientist
what is probability
Probability is the chance of something happening
NAtural experiment
You simply observe whats happening
Blind experiment
The test subjects don’t know which varible is which the controlled varible and the maniolutative variable are
Manipulated exppermenet
You have a controlled varible and variables that are changing
Double blind expermint
when the scientist and the test subject don’t know which is the controlled varible and the changing varible
Quantitate data
Expressed in numbers obtained by counting messerments
Qualtiative data
descriptive data describing nd involve charters tics that cannot be counted (describes qualities or characteristics)
control expriment
A controlled experiment is defined as an experiment in which all the variable factors in an experimental group and a comparison control group are kept the same except for one variable factor in the experimental group that is changed or altered.
observation
gathering infromtin using are 5 senses
inference
a conclusion reached on the basis of evidence and reasoning
