What I Need to Know

Investigation is the heart of science. It is the way scientists do

research. Scientific investigation is a way to find answers to a question that

will produce evidences that help you answer questions and solve problems.

When the evidence cannot provide answers or solutions then it may lead to

new questions or problems for investigation. As more knowledge are

discovered, science advances.

Researchers investigate the world in so many ways. In different fields

of science, they may use different methods and be guided by different

theories and hypotheses but most of them generally follow the steps in a

Scientific Investigation.

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. identify the steps in scientific method.

This module was designed and written with you in mind. It is here to help

you understand the process of Scientific Investigation. The scope of this

module allows you to use different learning situations. You need to be patient

in doing your tasks. Follow the directions in the activities and answer the

given test and exercises properly.

Lesson

1 Introduction to Scientific Investigation

What is Scientific Investigation?

Scientific Investigation is the way in which scientists and researchers

use a systematic process to answer questions about the world around us. It is

a way of finding the answer to a question using the carefully arranged steps.

In other words, the scientific method is a systematic process that involves

measurable observations to formulate, test or modify and prove a hypothesis.

What’s In

Activity 1: Arrange Me!

Below are steps in scientific investigation, arrange the following steps

in the proper order. Write numbers 1-7 (1 being the first step and 7 as the last

step). Write your answers in your Science activity notebook.

______________ a. Find out the problem

____________ b. Observe and record

____________ c. Make a hypothesis/ temporary solution or answer

____________ d. Communicate the result

____________ e. Identify the problem

____________ f. Arrive at a conclusion/ making of general statement

____________ g. Test the hypothesis

1. To explain or give meaning

2. Factor to be considered during an experiment.

3. Something that can change or influence the results of an experiment.

4. The inquiry or problem relating to a topic that can be answered by

conducting an experiment.

5. A method of doing investigation that include the steps such as identifying a

problem, gathering data, forming a hypothesis, testing a hypothesis, and

drawing a conclusion.

6. Following the rules of being fair and honest.

identified problem.

10. The general statement/s made by an investigator based on the results of

the experiment.

What is It

Steps in Scientific Method

Scientists are, by nature, keen observers that is why they can easily

perceive areas where problems exist. Having identified the problem, scientist

undertakes a carefully planned investigation following a systematic and logical

approach using steps in scientific method. The figure below shows the steps

in Scientific Investigation.

Figure 1. Steps in Scientific Investigation

6

1. Identifying Problems – The first step in

scientific investigations is to

identify a problem in a given

situation. This problem comes

when a researcher is curious

or interested about something

he/she has observed in the

environment.

2. Making Observations – The process of

science starts with an observation within the

surrounding of a researcher. In this step, the

scientist will research and make observations

regarding the problem.

3. Forming a Hypothesis – In this step, you will

give temporary solutions to the

identified problem.

4. Testing the Hypothesis/ Experiment – The

next scientific step you are going to is to test

your hypothesis. Some hypothesis may be

tested simply by further observations or take an

elaborate and tedious process as in the

experiment.

7

5. Organize and Analyze Data - After performing an

experiment and collecting data, one

must analyze the data. Research

experiments usually analyzed data

with statistical software in order to

determine the relationships among

the data gathered. In the case of a

simpler experiment, one would look at

the data and see how they show a

relationship.

6. Draw Conclusions – The next step of scientific investigation is to form a

conclusion. If the data support the

hypothesis, then the hypothesis is correct

and may be the explanation for the

phenomena. If the data do not support the

hypothesis, then more observations must

be made, a new hypothesis is formed, and

the scientific investigation is used all over

again.

7. Communicate 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.

8

What’s More

Activity 3: Fill in the Blanks

Directions: Fill in the blanks with the appropriate words from the vocabulary

list inside the box. Write your answers in your Science activity notebook.

The _________________ method is one way that people think about

and solve questions or problems. When you begin your experiment, it is

important to state a problem or _________________ that you would like to

find an answer to. It is important to look up or _________________ up-to-date

information about your topic before you conduct any experiments. A(n)

_________________ is a possible explanation about something.

scientific method: a method of doing research that includes the steps

of identifying problem, gathering data, forming a hypothesis,

testing a hypothesis, and drawing a conclusion

question: the inquiry or problem relating to a topic that can be

answered by conducting an experiment

experiment: a test or trial performed in order to discover something

hypothesis: an educated guess or reasonable assumption

procedure: a sequence of steps involved in performing an experiment

observe: to notice what occurs during an experiment

record: to write accurate information about what occurs during an

experiment

interpret: to explain or give meaning to

conclusion: the result or outcome of something

variable: something that can change or influence the results of an

experiment

ethical: following the rules of being fair and honest

research: to conduct and investigate into current information about

something

9

To conduct a(n) _________________ is a good way to discover

something new about science. Be sure to write down each step or

_________________ in the correct order before you start your science

experiment. When you conduct an experiment and you deliberately change

one thing, you are introducing a(n) _________________. It is critical to watch

or _________________ what is happening with every step of your

experiment. After you conduct your experiment, a valuable step is to write

down or _________________ what happened. When you explain what

happened in your experiment, you _________________ the results. Sharing

true information about the outcome of your experiment is an example of

_________________ behavior. After an experiment, it is important to write

down your _________________ or summary of what you learned.

What I Have Learned

Given the situations below, choose the letter that corresponds to your

answer and write an essay about what is ask in number two (2). Write your

answers in your Science activity notebook.

1. The mother of John wanted to find out the effect of organic fertilizer
