The Scientific Method
STEPS:
Step 1: Question
Step 2: Research
Step 3: Hypothesis
Step 4: Plan for the experiment
Step 5: Data Analysis
Step 6: Conclusion
Hypothesis Statement:
"If I put fenders on a bicycle [having fenders is the independent variable], then they will keep the rider dry when riding through puddles [the dependent variable is how much water splashes on the rider]
1.Independent- a variable (often denoted by x ) whose variation does not depend on that of another.
2.Dependent - a variable (often denoted by y ) whose value depends on that of another.
3.Controlled Variable-Controlled variables are quantities that a scientist wants to remain constant, and he must observe them as carefully as the dependent.
4.Control Group- used as a standard of comparison in a control experiment.5.Experimental Group-subjects that are exposed to the variable of a control experiment.
The hypothesis must be worded so that it can be tested in your experiment. Do this by expressing the hypothesis using your independent variable (the variable you change during your experiment) and your dependent variable (the variable you observe-changes in the dependent variable depend on changes in the independent variable).
