Does this sound familiar?
Where are My Shoes?
What should I have for lunch?
What class do I have next?
Did I do my homework for that class?
What is the cure for cancer?
Which deodorant works the longest?

Scientific Method Definition: A way to describe the steps of explaining a
scientific problem.
Note: there are several ways to explain the scientific
method. All methods use the overall process of
scientific investigation.
Let’s talk about the steps…
Problem/Question – Research – Hypothesis –
Experiment - Results/Analysis – Conclusion -
Communication

Problem/Question/Purpose
Problem – The focus question posed.
The BIG IDEA!
Examples – How did the children
become infected with salmonella?
Why did the plant die?
Why are my neighbor’s tomato plants
so healthy and tall?

Research/Background Knowledge
Research/Background
Investigate the problem.
Make observations and inferences and
gather information related to your
problem that would help you form a
hypothesis.

Hypothesis A possible explanation for a set of
observations or an answer to a scientific question.
A hypothesis should be:
A statement
Backed by information or research
TESTABLE!
Example: Tomato plants with Miracle Grow (a fertilizer) will grow two times faster than tomato plants without.

The Experiment
Testing the hypothesis
An experiment includes:
Materials- the items used in the
experiment
Procedure – the steps you take in the
experiment
Variables – factors that change in an
experiment
![Page 10: Scientific Method - Kyrene School District · Scientific Method Definition: A way to describe the steps of explaining a scientific problem. Note: there are several ways to explain](https://reader033.fdocuments.net/reader033/viewer/2022060420/5f17895a29f28b01934f10f2/html5/thumbnails/10.jpg)
Results/Analysis
Recording the observations and data of
the experiment and arranging the results
in an organized way.
Examples – tables, graphs (bar, line,
etc), qualitative observations and
quantitative observations

Conclusion Does the data support the hypothesis? If
so the hypothesis is supported. If not, it is rejected.
A conclusion is a detailed explanation, not just a sentence or two. It explains the data and infers why you got the results that you did.
This is where any ERRORS are mentioned. There are always errors!
A hypothesis can never be proven true, just supported.

Communication
This step is necessary in science so that
the scientific community knows the
findings as well.
This can be a lab report, an article in
a scientific journal, scientific
meetings, etc.

Is the Scientific
Method a Cycle? Or
does it end with the
last step?
