Physics Chapter 1 test
5 STEPS OF SCIENTIFIC METHOD:
1. recognize a problem 2. create a hypothesis 3. make a prediction 4. test prediction 5. verify/modify hypothesis
Which of the following statements is not true?
A good scientist is influenced by his or her likes and dislikes
T/F: A scientific fact is something that is absolute and unchanging.
False
Which of the following problems would NOT be a part of physics?
Identifying all the bones in a human body
A theory is...
a synthesis of a large collection of information that includes well-tested guesses.
Physics is the most basic science because...
all of the above
Science, art, and religion do not contradict one another because...
all three have different domains.
The difference between a hypothesis and a theory is that a hypothesis is...
an educated guess whereas a theory has been tested successfully many times in many ways
A scientific fact is...
close agreement by competent observers of observations of the same phenomena
A scientific hypothesis may turn out to be right or it may turn out to be wrong. If it is a valid hypothesis, there must be a test by proving that it is...
wrong
Which of these is a scientific hypothesis?
Atoms are the smallest particles of matter that exist
T test a scientific hypothesis you would...
set up an experiment and look at the results.
A hypothesis is...
An educated guess that has yet to be proven by experiment.
T/F: close agreement by competent observers about a series of observations of the same phenomena is known as a scientific theory.
False
The difference between a hypothesis and a theory is that a hypothesis...
Is a guess that has not been well tested, whereas a theory is a synthesis of well-tested guesses.
Which one of the following is NOT a part of the scientific method?
Repeat the experiments until the answers match the prediction.
T/F In science, an educated guess about the answer to a scientific question is called a hypothesis
True
T/F: A hypothesis is not scientific if there exists no test for attempting to prove it wrong.
True
T/F: The synthesis of a large collection of information that encompasses well-tested hypotheses about certain aspects of the natural world is known as a scientific theory.
True
T/F: When scientific findings are expressed mathematically, they are easier to verify or disprove by experiment.
True
