Scientific Method
A way of problem solving by making a hypothesis and testing it.
Scientific Method
A factor in an experiment that can exist in different amounts.
Variables
What is the first step of the scientific method?
Problem - Ask a Question
What questions does a Problem normally ask?
Who, what, when, where, why, or how
Scientists are the only individuals who use the scientific method True or False
False - WE ALL USE IT
What is the last step of the scientific method?
Conclusion
What is a hypothesis?

What 2 words should always be in your hypothesis statement?
If, Then
What type of data is measurable or countable?
Quantitative
What kind of observation is collected by using your senses and is descriptive?
Qualitative
The variable that is kept the same in an experiment
Controlled Variable
True or False? You can skip steps or change the order of the procedure.
False
Gathering information by using your senses
Observation
The question in an experiment that is being tested.
Problem
True or False? A good procedure will require multiple trials of testing to be conducted; this allows the data and results to be more reliable.
True
Data, details, and facts that support your claim
Evidence
A guess or conclusion based on your observations.
Inference
The variable that is changed in an experiment; also referred to as the manipulated variable
Independent
What is the fourth step of the Scientific Method?
Data and Results
The process of learning about the natural world through observation and experimentation.
Science
A scientist conducted an experiment to determine how the amount of salt in a body of water affects the plants that can live in the water. In this experiment the independent variable is
the amount of salt in the water
What are the steps to the scientific method?
Problem
Hypothesis
Procedure
Data and Results
The variable that is measured in an experiment; also referred to as the responding variable.
Dependent variable.
Different preservatives were tried in foods to determine which best restricted the growth of molds. What is the dependent variable?
Growth of Mold
What do both observations and inferences help us to form?
Conclusions
