Steps of the Scientific Method
This step is the first step of the scientific method
Make an Observation/Ask a question
A hypothesis is
An answer to the question being asked using research on the question
There are 2 important variables
Independent Variable and Dependent Variable
The Variable that is changed or manipulated
Independent Variable
Control variables
This step comes last in the Scientific Method
Making a Conclusion
Creating the hypothesis is this step in the Scientific Method
The Third Step
Variables that change are called
Independent variables
The Variable that is being measured is the
Dependent Variable
Scientists use the Scientific Method because
It helps scientists be orderly when conducting experiments so that their results are valid
A scientist measures the bounce of a Spalding basketball and a Nike basketball
Analyzing the data
Blue is the best color for a bedroom is a good hypothesis
No, it is not in the right format
In a good hypothesis, which variable comes first?
Independent Variable
If I change the amount of this_________, then I will see more or less of this variable___________
Independent Variable, Dependent Variable
List all the steps of the Scientific Method
Make an observation and ask a question; Create a hypothesis; Conduct an experiment; Collect and analyze data; Make a conclusion
This step is the step where a scientist tests their hypothesis
Conduct (Perform) an Experiment
A good hypothesis is written as
If (IV), then (DV) because (reason)
The dependent variable is
The variable that is being measured
Maya changed the amount of light one pot of her lilies were getting and did nothing to the second pot of lilies to see if the second pot would grow more. The independent variable is
The amount of sunlight the lilies receive/get
If a scientist is not able to support their hypothesis, the scientist will have to
Maddie thinks that if she switches the dog food she gives her dog to something with fewer ingredients, then her dog will weigh less. This step in the Scientific Method is
Creating a hypothesis
A good hypothesis has 3 things that are important to conduct a good experiment
IV, DV, Control Variables, Reason for the relationship between IV and DV
It is important to have only one Independent Variable because
It will be difficult to know what is being measured if you have many variables that you are changing
Jerry thinks that the amount of chocolate he eats as he studies will make his grades improve. The independent variable is____________ and the dependent variable is ______________
Amount of chocolate eaten as he studies; his grades
The purpose of a control group is to
Have a comparison for the variable that is being measured in the experiment
