What is the variable that is held constant in the experiment?

Responding Variable
The variable that is kept constant is called a(n) _______.
independent
dependent
control
data point
A ___________ gets tested with some sort of experimentation to collect data
purpose statement
conclusion
trial
hypothesis
Statement that describes WHAT always happens under certain conditions
Fact
hypothesis
law
theory
A well-substantiated explanation acquired through the scientific method and repeatedly tested and confirmed through observation and experimentation.
Fact
Hypothesis
Law
Theory
What is a fact?
a well-evidenced description of what happens
something that is known to be true
a well-evidenced explanation of how or why some phenomenon occurs
a proposed explanation made on the basis of limited evidence as a starting point for further investigation
Which statement best summarizes the difference between a scientific law and a scientific theory?
With enough evidence, a scientific theory can become a scientific law, therefore the law is a greater accomplishment.
A scientific law is a greater accomplishment because it is the proven answer, whereas a scientific theory is merely a proposed answer.
A scientific law and a scientific theory are both well-evidenced, but the theory is a greater accomplishment because it is an explanation of how or why, whereas the law is only a description of what will happen.
A scientific law is a greater accomplishment than a scientific theory, because a law is well-evidenced, whereas a theory is not based on evidence.
The role of the control group (the group that does not receive the treatment) is used in an experiment to
provide a basis for comparison to the experimental group.
prove that a hypothesis is correct.
ensure repeatability.
produce more accurate data.
none of the above
Which of the following statements regarding a valid scientific experiment is FALSE?
An experiment must have at least two values of the independent variable.
An experiment can test only one independent variable.
The only successful experiment is one that supports the hypothesis.
An experiment is done to test a hypothesis.
With further investigation, experimentation and a more evidence, a theory may eventually become a law.
True
False
