Steps of the Scientific Method
The first step in the scientific method
What is ask a question
The variable that the scientist changes on purpose in an experiment
What is independent variable
The "if" part of the hypothesis
What is the independent variable
The name for a trial conducted to test a hypothesis
What is experiment
True or false: the independent variable is the one you measure during the experiment.
What is false. (the IV is what you change; the DV is what you measure)
The step where you gather existing information and data related to your topic
What is conducting background research
The variable that your measure in response to changes
What is dependent variable
The "then" part of the hypothesis
What is the dependent variable
Why do scientists perform multiple trials of an experiment?
What is to ensure accuracy and reliability of the results.
True or false: A hypothesis can be proven completely true.
What is false. (a hypothesis can be supported, but not definitively proven)
The step after forming a hypothesis
What is perform an experiment
The variables that are kept the same throughout the experiment
What are constants
True or false: A hypothesis must always be correct.
What is false. (It can be supported or refuted by the experiment)
The 2 types of data collected in an experiment
True or false: A good experiment only changes one variable at a time.
What is true.
The step after analyzing data
What is draw a conclusion
The name of the group in an experiment that does not receive the experimental treatment and is used for comparison.
What is the control group
The definition of hypothesis
What is a testable prediction based on observations that describes a cause and effect relationship between variables.
The name for information collected during an experiment
What is data
True or false: Observing patterns in data helps scientists form a hypothesis.
What is true.
The step that involves sharing the results of your experiment with others
What is communicate your findings
If you're testing the effect of sunlight on plant growth, what is the independent variable?
What is amount of sunlight
What hypotheses are based on
What is research or observations
The step scientists should take if the results of an experiment do not support the hypothesis
True or false: The conclusion of an experiment must always support the hypothesis.
What is false. (the conclusion can either support or refute the hypothesis)
