Scientific Method
A series of steps designed to help you solve problems and answer questions. (Triple Points)
A) scientific method
B) experiment
C) hypothesis
D) observation
A) scientific method
what is a factor, feature, or quantity that can be changed or measured during an experiment?
Variable
What is the 1st step of the scientific method?
Make an Observation
The information (evidence) gathered from observations and experimentation is called
Data
Scientists are the only individuals who use the scientific method True or False
False - WE ALL USE IT
What step in the scientific method involves interpreting your data and making a final determination about your results?
Conclusion
What is a hypothesis?
An educated guess or prediction of what you think the outcome will be
What 2 words should always be in your hypothesis statement?
If, Then
All questions or problems that we want to use the scientific method for must be ______________.
400 points
Testable
In order to insure accurate results all experiments must be _______________.
A. Repeated multiple time
B. Done only once
A. Repeated multiple time
This stays the same or is kept the same during an experiment or test.
Constant
True or False: It is important to conduct multiple trials in an experiment.
600 points
True
Gathering information by using your senses
Observation
True or False: The scientific method can only be used to answer scientific questions or problems.
False
What is the second step of the scientific method?
Doing research on your topic
True or False: An experiment is successful when new information is learned, even if the original hypothesis is not supported by the results of the experiment.
True
When a scientist shares their findings with other scientists, what step of the scientific method are they completing?
Sharing Results
The variable you manipulate, control, or vary in an experimental study to explore its effects. Double points
A. | Dependent |
B. | Independent |
C. | Control |
D. | Uncontrolled |
B- Independent

Plant A
What step of the scientific method has us making sense of the data, looking for patterns, finding trends, ect.
