7 Steps of the Scientific Method
• IDENTIFY the problem
•BACKGROUND INFORMATION
•HYPOTHESIS
•Design and Conduct EXPERIMENT
•RECORD YOUR DATA
•ANALYZE / INTERPRET: (graphs)
•CONCLUSION
• IDENTIFY the problem: what is the question we are trying to solve
•GATHER basic information: about your problem do some background research
•STATE your HYPOTHESIS! (what you are trying to prove, often stated as an “if….then …”)
sometimes the 3 are combined

7 Steps of the Scientific Method
•EXPERIMENT: (design and conduct your experiment to test your hypothesis)
•RECORD YOUR DATA: (record your results with words or tables, or both)
•ANALYZE AND INTERPRET: (think about your results, identify trends, make inferences, perhaps prepare charts or graphs)

7 Steps of the Scientific Method
•STATE YOUR CONCLUSIONS: *should answer your hypothesis based upon your experiment, observations and data
*should be in a well formed paragraph
*should state whether your original hypothesis was right or wrong

7 Steps of the Scientific Method
Example:
•What do we know about plants, what do they need?
•Do we know for sure how much water they need?
•Let’s follow the 7 steps of the Scientific Method

7 Steps of the Scientific Method
Step1: Identify the problem - How much water is the best for my plants?
Step2: Gather background information - a)Referral --ask Mr. Cohen or Mr. Ryal
b)Research -- look it up on the internet
c)Expert -- go ask somebody at the plant store

Step3: State my Hypothesis
““If I water my plants three times per If I water my plants three times per week then they will grow the best”week then they will grow the best”

7 Steps of the Scientific Method
1. Use three plants
2. Water Plant 1, one time per week
3. Water Plant 2, two times per week
4. Water Pant 3, three time per week
7 Steps of the Scientific Method
WAIT: Before I begin my experiment,
Do the plants need the same amount of sun?
Do I have to use the same type of soil?
Do I have to use the same type of plant?
Do I have to give each the same amount/type of fertilizer?

STEP 7: STATE YOUR CONCLUSIONS!
Since Plant #2 grew the best, I should water my plants 2 times per week. I should not water my plants 3x times per week.
My hypothesis was not correct.
Notice how my conclusion relates back to my hypothesis!

IMAGINE you are Galileo at the leaning Tower of Pisa.
Your notice things fall to earth because of gravity.
You hypothesize: That heavier objects fall first.
You design an experiment:
You conduct observations:
You interpret your results
You state a conclusion:
Lets see how this works!
