How many steps are there to the
Scientific Method? Name as many
as you can.
1) Observe
2) Question
3) Hypothesis
4) Experiment
5) Results/Conclusion

2. DIRECTIONS 8/7/17
Read the “Scientific Method Science
Safety Rules” on your handout you just
received
Underline & number the broken safety
rules (using pencil)
How many did you find?
Sit quietly & be ready to share!

3. THE SCIENTIFIC METHOD

4. WHAT IS THE SCIENTIFIC
METHOD?
The Scientific Method is a general
pattern followed by scientists
when conducting an experiment.
Is there only one version of the
scientific method?
No…there are many variations of it,
but all seek to identify a problem
and provide an organized method
for conducting and analyzing an
experiment!

5. THE STEPS OF THE SCIENTIFIC
METHOD
Observe
Question
Hypothesis
Experiment
Results/Conclusion

6. OBSERVE
You observe a topic that can
generate questions for further
research.

7. QUESTION
You ask a question about
what is being observed.
Identify the problem or
question.

8. HYPOTHESIS
Based on your observations, you
make an educated guess on what
you think the outcome of the
experiment, or the answer to your
question will be.
Do you ever change
your hypothesis after
realizing it didn’t turn
out the way you thought
it would?
NO!!

9. EXPERIMENT
You will develop and follow a
procedure to test your hypothesis.
The outcome must be measurable.

10. RESULTS/CONCLUSION
You will record the results of your
experiment, and repeat the experiment
if needed. You will state if your
hypothesis was accepted or not and
explain your results.

11. • All factors are the same for the
control and experimental groups
EXCEPT for one. The ONE factor
that differs is called the VARIABLE.
• Any differences observed are
most likely caused by the
VARIABLE.
CONTROL GROUP &
EXPERIMENTAL GROUP-

12. WHAT ARE THE VARIABLES
IN AN EXPERIMENT?
Independent Variable- the variable that is
intentionally changed in an experiment to
observe its effect on the dependent variable.
Dependent Variable- What is observed during
the experiment; It changes as a result.
Controlled Experiment- Changing one factor
and observing its effect on another while
keeping all other factors constant.

17. REVIEW 1
Which step in the Scientific Method is given here?
If I water and feed the plants, then they will grow to be
tall and healthy.
1- Observe
2- Question
3- Hypothesis
4- Experiment
5- Results/Conclusion
Hold up your
answer using
your fingers…
1, 2, 3, 4, or 5

18. CORRECT!
An educated guess, hypothesis, is made to determine
the effect water and food will have on the growth of
plants.

19. REVIEW 2
Which step in the Scientific Method is given here?
My hypothesis is accepted. When I watered and fed
the plants daily, they grew.
1- Observe
2- Question
3- Hypothesis
4- Experiment
5- Results/Conclusion
Hold up your
fingers…
1, 2, 3, 4, or 5

20. CORRECT!
The results from the experiment were stated and a
conclusion was made.

21. REVIEW 3
Which step in the Scientific Method is given here?
Today while walking home, I noticed that the plants in
my front yard were starting to die.
1- Observe
2- Question
3- Hypothesis
4- Experiment
5- Results/Conclusion
Hold up your
fingers…
1, 2, 3, 4, or 5

22. CORRECT!
A simple observation was made about flowers.

23. REVIEW 4
Which step in the Scientific Method is given here?
Why is it that some plants are growing, and other
plants are dying? What affects the growth of plants?
1- Observe
2- Question
3- Hypothesis
4- Experiment
5- Results/Conclusion
Hold up your
fingers…
1, 2, 3, 4, or 5

24. CORRECT!
Questions were formed about the flowers. These will
be the questions carried out through the
experiment.

25. REVIEW 5
Which step in the Scientific Method is given here?
To answer my questions, I watered and fed the plants
daily and recorded my findings.
1- Observe
2- Question
3- Hypothesis
4- Experiment
5- Results/Conclusion
Hold up your
fingers…
1, 2, 3, 4, or 5

26. CORRECT!
An experiment was carried out to answer the
questions to my problem.
