What does method mean?
  1. Graph to interpret
  2. Data to record
  3. Steps to follow

7 Steps of the Scientific Method
  • IDENTIFY the problem
  • BACKGROUND INFORMATION
  • HYPOTHESIS
  • Design and Conduct EXPERIMENT
  • RECORD YOUR DATA
  • ANALYZE / INTERPRET (graphs)
  • CONCLUSION

7 Steps of the Scientific Method
  • 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?
  • Lets 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

three times per week then they will grow the best

Step 4 DESIGN AN EXPERIMENT!
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
Step 4 DESIGN AN EXPERIMENT!
  • 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.
33
You design an experiment You conduct
observations You interpret your results You
state a conclusion Lets see how this works!
34
LET TRY Galileo's
EXPERIMENT
35
Did your conclusion agree with your
hypothesis? Is that OK?
36
LET Take a QUIZ!
