1. Steps to Scientific Method
Designing an Experiment

2. Steps to Scientific Method
1) OBSERVE
“You can observe a lot just by watching.” Yogi Berra
You see something happen and you ask “Why?”

3. Steps to Scientific Method
2) Formulate a QUESTION
Decide what you want to know or find out

4. Steps to Scientific Method
3) RESEARCH AND COLLECT DATA
See what you already know

5. Steps to Scientific Method
Formulate a HYPOTHESIS
A hypothesis is an “if…then” statement
Example: “If I do this, then this will happen.”

6. INDEPENDENT AND DEPENDANT VARIABLES
The independent variable is the part that you choose to change and test (the word “variable” means to change)
The dependent variable is the part that you measure or count; it is the outcome

7. Steps to Scientific Method
TEST THE HYPOTHESIS
Run the experiment and test the change that you make (IV)

8. Steps to Scientific Method
OBSERVE
Consider the results of the experiment

9. Steps to Scientific Method
DRAW A CONCLUSION
Evaluate the hypothesis
