Hi, young scientists! I am Jay. Today we will learn
about the scientific method. I am sure that you are
excited to learn. Come on! Let’s explore more with
the help of my friends!
A. Introduction
is a systematized body of knowledge
based on facts, unbiased observations
and systematic experimentation. Science
came from the Latin word “Scientia,”
meaning knowledge.
Wow! Now, I know why
we follow steps when
making experiments.
Teacher Jella,
what is science?
2
It is a process used to find answers to questions about the things
around us.
It involves the application of scientific knowledge and problemsolving skills. It can be done anywhere.
Here are the different
STEPS IN
SCIENTIFIC METHOD.
1. Observation and identification of the problem
Researchers make observations around them to spot
problem areas. Then, they identify the specific problem
they want to study.
Problem - this is the question that you are trying to
answer or problem that you are trying to solve. Try to
narrow it down and be very specific.
produce
Example: Do santan plants need much sunlight to
many flowers?
2. Formulation of hypothesis
Hypothesis - an educated guess.
- a temporary answer to a problem.
-a prediction based on data
- it is what you think the answer based upon
your gathered information.
Example: Santan plants need much sunlight to
produce many flowers.
3. Experimentation
•This is the stage where the hypothesis is tested.
•This is broken into two parts, materials, and procedure.
•Materials is a list of equipment that you will need for the
experiment.
3
•Procedure is a list of instructions that you need to follow
the experiment.
for
Variables - factors that affect the result of the experiment.
Three Kinds of Variables
•Independent (manipulated) variable – the variable that is
changed in the experiment to see its effect.
•Dependent (responding) variable – the factor being affected by
the independent variable.
•Controlled variables – variables that stay the same all
throughout the experiment.
Two Types of Groups:
•Experimental setup – the setup in which change is applied.
•Control setup – the setup that is used as a standard for
comparison.
4. Analysis of Data
•The analysis and interpretation of data gathered from the
experiment allow the researchers to list the findings of their
study.
5. Conclusion
•It the answer to the question of the experiment.
•Based on the findings of the experiment, the researchers draw
generalization about the problem they are investigating.
•It is OK if it turns out that your hypothesis was not correct. What
you learned is more important.!
6. Communicate your results
•One of the most important parts of the scientific method I
report to others your findings.
•You will help others learn.

d. draw conclusions
D. Review
The scientific method is a process for experimentation that is
used to explore observations and answer questions. There are six steps
in the scientific method. The first step is the observation and
identification of the problem. This step is done through the use of our
senses. The second step is the formulation of hypothesis. A hypothesis is
an educated guess or a possible answer to your problem. To test the
hypothesis it must undergo experimentation which is the third step in
the scientific method. In the experimentation, we are dealing with
variables. A variable is anything that can change or be changed. In
other words, it is any factor that can be manipulated, controlled for, or
measured in an experiment. There are three types of variables. These
are independent, dependent, and controlled. The next step is the
analysis of data. In this step, the collected data from the experiment
and interpretation of data gathered from the experiment allow the
researchers to list the findings of their study. The fifth step is conclusion
which is based from the findings of the experiment. Here, the
researchers draw generalization about the problem they are
investigating. Lastly, communicate your results. One of the most
important parts of the scientific method is to report to others your
findings so you can help them to learn.

________________b. Communicate your results
________________c. Observation and identification of the problem
________________d. Conclusion
________________e. Experimentation
________________f. Formulation of hypothesis

On the activities, you have observed that critical thinking is a key
component in the scientific method. Without it, you cannot use logic
to arrive to conclusions. Moreover, when making an experiment, there
should be a dependent variable (which does not change) and an
independent variable (which does change). An experiment should
include an experimental group and a control group. The control group
is what the experimental group is compared with.
It is important to follow the step by step procedure of the
scientific method to have a reliable conclusion. Skipping or mixing up
steps may lead to wrong conclusions or even danger. Therefore, it is a
must to stick with the steps and do them properly.
The scientific method was used even in
ancient times, but it was first documented by
England's Sir Francis Bacon (1561–1626) who set up
inductive methods for scientific inquiry. The scientific
method can be applied to almost all fields of study
as a logical and rational problem-solving method.

Guide Card
Science is more about doing than knowing. Scientists are always
trying to learn more and to gain a better understanding of the natural
world. There are basic methods of gaining knowledge that are
common to all of the sciences. At the heart of science is the scientific
investigation. A scientific investigation is a plan for asking questions
and testing possible answers in order to advance scientific knowledge.
You are probably familiar with flow charts, like the steps followed
in a scientific investigation. The series of steps in a flow chart is
frequently referred to as the scientific method. This was discussed to
you in the previous lesson. Science textbooks often present this simple,
linear "recipe" for a scientific investigation. This is an oversimplification
of how science is actually done, but it does highlight the basic plan
and purpose of any scientific investigation: testing ideas with
evidence.

APPLE EXPERIMENT
Jaira is slicing an apple when she observes that after
some time the sliced apples turned brown. She wants to
prevent the apple from turning brown after being sliced. She
thinks that dipping apple slices into different liquids will slow the
process of browning. She used lemon juice, milk, and water. She
recorded her observations in after 30 minutes.

B. Learning Competency
Main Task:
The learner should be able to describe the components of a
scientific investigation. (S7MT-Ia-1)
Subtask:
The learner should be able to:
apply the different steps of scientific investigation.
appreciate and value the importance of scientific investigation.
C. Pre-assessment
Direction: Write true if the statement is true or false if the statement is
false. Write your answer on your notebook.
1. __________An experiment investigates the effects of the
dependent variable on the independent variable.
2. __________Only conclusions that support the hypothesis
should be reported in scientific research.
3. __________The steps of the scientific method must not
always be followed in a certain sequence.
4. __________A scientific investigation is generally
undertaken to answer a question.
5. __________A testable hypothesis can be proven true if it
really is false.
6. __________Results of an investigation are not reliable if
they have been replicated.
7. __________You cannot apply the scientific method to
answering a question in your daily life.
8. __________Scientific method is a series of logical steps for
testing a hypothesis.
9. __________Observations cannot be made with different
senses.
10. __________Methods used by scientists to communicate
the results of their research include publishing papers.
16
D. Review
Steps of a scientific investigation include observing and identifying a
research question or problem, forming a hypothesis, experimenting,
analyzing evidence or data, drawing conclusions, and
communicating the results. Scientific investigation must be guided by
ethical rules. They help ensure that the research is done safely and
the results are reliable.

Scientific investigation method is a systematic way of
gaining scientific knowledge. It trains us to think critically and
creatively and also trains us to be more observant and more
analytical. It gives us a standard approach in investigating the
phenomena around us like conducting investigatory
projects. Investigatory project is basically any science experiment in
whihc you start with an issue or problem and then, conduct
research or an investigation to decide whether what you think
matches with the actual outcome.
Through science investigatory projects, students develop their
scientific investigation and acquire knowledge of the different
scientific concepts, theories, principles and laws of nature. They use
their higher-order processes or thinking skills in conducting a study.
Enrichment Card
Hello! Are you still there? Let’s be more enlighten about
scientific investigation by answering the following
questions. Is that okay with you? Oh, that’s great. I know
you can do it. :)
Making observation is very important
because it sparks someone’s curiosity.
Without it, there will be no inventions
and discoveries. And to make
observations, we rely on our senses.
20
Question 1: What senses do you use when you observe?
a.
b.
c.
d.
e.
Data are the information gained from
observing and testing an
experiment. Scientists use data to gain
understanding and make
conclusions. Scientists often use graphs or
tables to show their data and research
findings.
Question 2: What are the two types of data? Use the
jumbled letter as your clue.
a. VUAQLE ITATI- ______________________
b. NAITVQUATITE - _____________________
Importance of Scientific Investigation
Necessity is the mother of invention. A need or
problem encourages creative efforts to meet the need
or solve the problem. And one of the efficient way to
solve problems is scientific investigation.
All of us is a scientist. We don't need to be a scientist and go to a
laboratory to perform scientific method. And just because it has the word
“scientific” in it, doesn’t mean that it’s hard to understand or apply. In
fact, you most likely already use the scientific method all the time.
Scientific investigation can help us in our everyday life. Scientific
investigations helps many scientists in solving problems and in making
their experiments, but not only scientific problems can be solve by it's
steps. It has also a potential to help us to be successful in our everyday
life and solve many personal problems of a ordinary people.
