3. LEARNING OBJECTIVES
Define scientific method;
use the scientific method to create an experiment in
their daily life;
recognize the importance of scientific method in
solving a problem.
10. 1. Make an observation.
Let's suppose that you get two slices of bread, put
them into the toaster, and press the button. However,
your bread does not toast.
11. 2. Ask a question.
Why didn't my bread get toasted?
12. 3. Form a hypothesis.
This hypothesis is not necessarily the right explanation. Instead, it's a possible explanation that
we can test to see if it is likely correct, or if we need to make a new hypothesis.
A hypothesis is a potential answer to the
question, one that can somehow be tested.
13. 4. Make predictions.
A prediction is an outcome we'd expect to see
if the hypothesis is correct.
14. 5. Test the predictions.
If the toaster does toast, then the hypothesis is supported—likely correct.
If the toaster doesn't toast, then the hypothesis is not supported—likely wrong.
To test the hypothesis, we need to make an
observation or perform an experiment associated
with the prediction.
15. 6. Iterate.
The last step of the scientific method is to reflect on our results
and use them to guide our next steps.

17. Let’s Do the Scientific Method Way!
TEAM A
Imagine you wake up on a
Saturday,and you couldn’t find your
cellphone. Solve the problem using
the scientific method.
TEAM B
Using the steps in Scientific Method,
learners are going to make a fried
chicken that is even better than their
mom or better than KFC.
TEAM C
Using the steps in scientific method,
solve your everyday question about
what is the fastest route from my
house to school?
TEAM D
Think critically about how scientist
prove that the planet is getting
warmer (eventually leads to climate
change). Use the steps in scientific
method.
20. The Scientific Method
What is the scientific
method?
•It is a process that
is used to find
answers to
questions about
the world around
us.
21. The Steps of Scientific Method
1) Make an observation.
a. Use your 5 senses!
b. Not all senses have to be used at the
same time.
c. Example: Some plants are taller
than other plants.
22. c. Example: Will fertilizers increase the
growth rate of plants?
2) Ask a question.
a. Pose a question to try to figure out why you
observed what you did.
b. Scientists often ask a question after making
many observations.
The Steps of Scientific Method
23. 3) Formulate Hypothesis, or write or develop
a possible explanation for the problem.
a. NOT a question, always a statement
b. A hypothesis is a prediction, or an educated guess.
c. Always written as: “IF…, THEN…, BECAUSE…”
d. Example: If fertilizer is added to trees, then the
plants will grow faster because the added nutrients
will speed their growth.
24. 4) Test Hypothesis
a. Design a test that will support or disprove
your hypothesis.
b. The test should be repeatable (you conduct
the test more than once and get the same
results every time).
25. 5) Analyze/Interpret the results.
a. After you have measured and recorded information, what
do they mean?
b. Did the trees with the fertilizer (experiment group) grow
more than those in the control group (without the
fertilizer)?
26. 6) Draw conclusions.
a. Look back at your hypothesis.
b. Does your data support your hypothesis or
reject it?
27. GENERALIZATION
In most cases, the scientific method is an iterative
process. In other words, it's a cycle rather than a
straight line. The result of one go-round becomes
feedback that improves the next round of question
asking.
