What I Need to Know
The second to the last step of the scientific method is to state your
conclusion. Conclusions in science are reliable, although it is tentative;
science is always a work in progress. Scientific conclusions are tentative
because all ideas are open to examination for further improvement.
Drawing conclusion is utilizing information that is implied to make
meaning out of what is not clarified. When a conclusion is drawn, the validity
of the conclusions and the research findings will be presented. On the other
hand, communicating results is the sharing of results to others and allowing
them to scrutinize your work for further enhancement.
After going through this module, you are expected to describe the
components of a scientific investigation (S7MT-Ia-1).
Specifically, you are also expected to:
1. differentiate law from theory;
2. formulate a conclusion; and
3. relate the importance of communicating results in solving problems to
others.
This module was designed and written with you in mind. It is here to help
you master the last two steps in Scientific Method: Drawing a Conclusion and
Communicating Results. The scope of this module permits you to use
different learning situations. You have to extend your patience in
understanding and analyzing what you are reading. Follow the directions in
the activities and answer the given test and exercises properly.

What is It
Step 6. Drawing a Conclusion
A conclusion is a statement
about the results of the experiment.
You
compare
the
results
of
the
experiment with the hypothesis. If the
data supports the hypothesis, then the
hypothesis may be the explanation for
the problem. If the data do not support
the
hypothesis,
then
more
observations will be made, a new
hypothesis will be formed, and the
scientific method will be used.
When a hypothesis has been tested many times under many different
conditions and has been found to explain a group of observations, the
hypothesis becomes a theory. Theories are explanations for some problems
based on observations, experimentation and reasoning. While, if the same
results have been obtained for so many times by different scientists, the
summary of these experimental results becomes a law. Laws are summaries
of many experimental results and observations. Laws are not the same with
theories because laws tell only what happens, not why it happens.
7
Step 7. Communicating Results
When a conclusion is drawn, the
research can be presented to others to inform
them of the findings and receive input about
the validity of the conclusion drawn from the
research. Reporting one’s research let other
scientists repeat the investigation to see
whether they get the same results. Getting
the same results when an experiment is
repeated is called replication.
If results can be replicated, it means they are more likely to be
corrected. Replication of investigations is one way that a hypothesis may
eventually become a theory.
