Module 3: Science Investigations

Hi girls! Welcome to Module 3.
How are you so far in the past two modules? Good job for putting
effort in learning and answering all the practice activities. I hope
you have adjusted a little this time in our online learning.
In this module we will be learning on:

COMPONENTS OF A SCIENTIFIC INVESTIGATION
Science Process Skills
The Scientific Method

Goals of the Subject: To deliberately develop in the students the capacity to do scientific

thinking, critical thinking, and problem-solving real life situations.

At the end of this module, you will be able to:
1. Identify components that should be included in a science investigation.
2. Perform an activity involving the science process skills.
3. Design or conceptualize a simple scientific investigation at home.

Essential Questions

Lesson 1: Science Process Skills

There are different ways to answer this question. Maybe
some will go online and research for the answer, or perhaps
others will conduct an experiment to try and see it for
themselves.
Of these two approaches, which one will you most likely do?
Of course, you have your own choice.
But the best way to answer this is by conducting a simple
investigation.

Let’s review first one important concept: The Science
Process Skills.

KEY CONCEPT 1

SCIENCE PROCESS SKILLS
The science process skills form the foundation for scientific methods. These
basic skills are integrated together when scientists design and carry out
experiments or in everyday life when we all carry out fair test experiments. All
the six basic skills are important individually as well as when they are integrated
together.

Module 3
September 7-18, 2020

Lesson 1: Science Process Skills

Let me describe each skill to you.

Observing
This is the most basic skill in science. Observations are
made by using the 5 senses. Good observations are
essential in learning the other science process skills.
Example:
The learner will be blindfolded and make observations
using the sense of feeling as she places her hands
inside a brown bag filled with different objects.

Classifying

After making observations it is important to notice similarities,
differences, and group objects according to a purpose. It is
important to create order to help comprehend the number of
objects, events, and living things in the world.
Example:
The learner will group them together according to criteria. The
ones that are hard will be in one group. The remaining objects
that are soft will be all together in another group.

Predicting

What do you think will happen? It is an educated guess based on good
observations and inferences about an observed event or prior knowledge.
Example:
The learner can ask herself and give a good guess on what will happen if
she leaves the hard objects under the summer heat of the sun for a week.

Module 3

Lesson 1: Science Process Skills

Inferring

When you infer, you make an explanation based on an
observation. It is a link between what is observed and what is
already known.
Example:
The learner observes that the object is soft and states a
reason that it is soft because it was made from light, cheap,
not of good quality materials.

Measuring

Measuring is important in collecting, comparing, and interpreting data. It

helps us classify further and communicate with others. The metric system

should be used to help understand the scientific world.

Example:
The objects that were observed earlier can be measured using the different
tools for measuring with metric system (SI units). Such as in mm, cm, m,
etc.

Communicating

When you are communicating, you are sharing your experiences or the

result of your experiment. This can be done with graphs, diagrams, maps,

and spoken words.

Example:
The learner shares the outcome of her experiment. She uses graphs,
diagrams, and maps to explain the result of her research visually and
clearly.

These basic skills are integrated together when
scientists design and carry out experiments or in
everyday life when we all carry out fair test
experiments.

All the six basic skills are important individually as well
as when they are integrated together.

Lesson 2: The Scientific Method

KEY CONCEPT 2

SCIENTIFIC METHOD

It is a series of steps followed by scientific investigators
to answer specific questions about the natural world. It
involves making observations, formulating a
hypothesis, and conducting scientific experiments.
Scientific inquiry starts with an observation followed by
the formulation of a question about what has been
observed.

12/20 Let me describe clearly each step to you in
the next pages.

Lesson 2: The Scientific Method

STEPS OF THE SCIENTIFIC METHOD

OBSERVATION

The first step of the scientific method involves making an observation
about something that interests you. This is very important if you are
doing a science project because you want your project to be focused
on something that will hold your attention. Your observation can be on
anything from plant movement to animal behavior, as long as it is
something you really want to know more about. This is where you come
up with the idea for your science project.

QUESTIONS

Once you've made your observation, you must formulate a question
about what you have observed. Your question should tell what it is that
you are trying to discover or accomplish in your experiment. When
stating your question you should be as specific as possible. For
example, if you are doing a project on plants, you may want to know
how plants interact with microbes. Your question may be: Do plant
spices inhibit bacterial growth?

Lesson 2: The Scientific Method

STEPS OF THE SCIENTIFIC METHOD

HYPOTHESIS

The hypothesis is a key component of the scientific process. A
hypothesis is an idea that is suggested as an explanation for a natural
event, a particular experience, or a specific condition that can be tested
through definable experimentation. It states the purpose of your
experiment, the variables used, and the predicted outcome of your
experiment. It is important to note that a hypothesis must be testable.
That means that you should be able to test your hypothesis through
experimentation. Your hypothesis must either be supported or falsified
by your experiment. An example of a good hypothesis is: If there is a
relation between listening to music and heart rate, then listening to
music will cause a person's resting heart rate to either increase or
decrease.

14/20 EXPERIMENTS

Once you've developed a hypothesis, you must design and conduct an
experiment that will test it. You should develop a procedure that states
very clearly how you plan to conduct your experiment. It is important
that you include and identify a controlled variable or dependent variable
in your procedure. Controls allow us to test a single variable in an
experiment because they are unchanged. We can then make observations
and comparisons between our controls and our independent variables
(things that change in the experiment) to develop an accurate
conclusion.

STEPS OF THE SCIENTIFIC METHOD

RESULTS

The results are where you report what happened in
the experiment. That includes detailing all
observations and data made during your
experiment. Most people find it easier to visualize
the data by charting or graphing the information.

CONCLUSION

The final step of the scientific method is developing a conclusion. This is
where all of the results from the experiment are analyzed and a
determination is reached about the hypothesis. Did the experiment
support or reject your hypothesis? If your hypothesis was supported,
great. If not, repeat the experiment or think of ways to improve your
procedure.

Instructions

Week 1:
1. Individually, observe your surroundings at home or your community. Is
there something that you want to remedy, scientifically? List them
down in your science notebook.

2. Then, as a group, meet to discuss among your group mates if they have
the same problem as well. From the lists that you have, choose one
problem that you want to solve. You have to decide and agree what
that problem is. Clearly identify it. Please do not invent a problem.
Then discuss further how to design your own experiment to answer
this problem following the steps of the scientific method.
