What is the first step of The Scientific Method?
Ask a question.
What is the second step of The Scientific Method?
Do research.
What is the third step of The Scientific Method?
Form a hypothesis.
What is an educated guess called?
Hypothesis
What is a variable?
Something that changes
What is the one variable you change on purpose?
The Independent Variable
What is the fourth step of The Scientific Method?
Perform the experiment(s).
What are the Control Variables?
The variables that stay the same.
If I design an electromagnet experiment where I change the number of coils to see how many paper clips can be picked up, what is my dependent variable?
Dependent variable = Number of paperclips picked up
That's what changed as a result of changing the number of coils.
Which variable is the change that is the result (measured) of the experiment?
The Dependent Variable
What is the fifth step of The Scientific Method?
Analyse the data.
What is the Independent Variable?
The one variable you change on purpose.
What is a hypothesis?
An educated guess
What are the variables that stay the same?
The Control Variables
What is the sixth step of The Scientific Method?
Form a conclusion.
Which is the dependent variable?
The variable that is the change that is the result (measured) of the experiment?
What 3 things must a hypothesis be?
Clear, Brief, Testable
If I design an electromagnet experiment where I change the number of coils to see how many paper clips can be picked up, what is my independent variable?
Independent variable = Number of coils
That's what I changed on purpose.
How many independent variables can you have?
One
A good hypothesis contains what three words?
If, then, and because
