Test 1 - Scientific Method Flashcards
Why do we use the scientific method?
It is an organized way of solving a problem that is used unconsciously daily.
What are the steps of the scientific method?
Establish a problem Form a hypothesis Observe and record the data Classify and analyze the data Verify your answer Predict your outcomes
What does the problem have to be?
Observable
Measurable
Repeatable
What are the steps to establishing a problem?
Defining and researching the problem
What is a hypothesis?
An educated guess about how to solve the problem
What can be found after researching and defining the problem?
A solution
When can you find the solution?
After researching and defining the problem
Where does the experiment happen?
Observing and recording the data
What are the three parts of experiments?
Variables, controls, and constant
What is the independent variable?
What is added to solve the problem
What does the independent variable effect?
The dependent variable
Which variable is the “if” part of the hypothesis?
Independent variable
Where do you graph the independent variable?
X axis
What are two definitions for dependent variable?
What is being tested and
The problem we are trying to solve
What does the dependent variable do?
Responds to the independent variable
What part of the hypothesis is the dependent variable?
The “then” part
Where is the dependent variable graphed?
The y axis
What is a constant?
What is kept the same
How many variables are tested during an experiment?
1
What is the control group?
The group that doesn’t experience the change
Why is there a control group?
To see if the independent variable works
What is one thing not all experiments have?
A control groou
How do you classify data?
Put it in a chart or table
What is involved in analyzing the data?
Looking at the data for trends of support for the hypothesis
