Development Team
Dear Parents,
The Schools Division of Calamba City is one with every Filipino family in
coping with the demands of our modern times amidst Covid–19 Pandemic.
The Division initiated Self Learning Module (SLM) aims to meet the most
essential learning competencies required to be learned by your child whether your
child opts for online, modular or blended learning modality. The learning activities in
this SLM are arranged chronologically from simple to complex to lead your child to
think critically, act skillfully, and reflect deeply on each lesson and practice into real
life skills. Most importantly, this SLM promotes self-paced learning as your child can
always review the least understood lessons as often as he/she pleases.
Thank you in advance for being one with us! Together, let us envision that, by
the end of this school year, we will see your child as one responsible young person
with a heart and mind for humanity, for nature, for the country, and for God.
Dear Learner,

Please take time to read and do the activities in these SLM as if you are
reporting in school. Set a regular study schedule for you as much as possible, but
keep in mind that these SLM will enable you to learn at your own pace. If you do not
understand a lesson, the SLM would not mind you flipping back the pages repeatedly
for review. Also, remember to keep in touch with your teachers. Send them a
message through your online sessions or write them a note as you do your modular
activities.
We wish you good luck in your studies, and we hope that you will remain
happy and enthusiastic in learning!

5. cite the importance of science processes in finding solutions of a given
problem
I What is new
Science Processes
Science is a way of gathering and organizing information about the natural world. It
involves more than the absorption of information. More than anything else, science is
inquiry, investigation, and discovery. That is how scientific progress is made.
Can you identify the processes illustrated given the clues on the next page?

Hints/ Clues
OBSERVING
We use our senses to gather I formation about the things and events around us. We
identify the characteristics of objects such as color, texture, size, taste, or
MEASURING
INFERRING
PREDICTING
We are making an “intelligent guess” about the outcome of an experiment. We base our
prediction on observable facts or trends and patterns in an experiment.

CLASSIFYING
We look for a common attributes that can help explain why something happens
COMMUNICATING

a. control variable c. dependent variable
b. constant variable d. independent variable
15. A botanist wants to see how different colored light waves influence the
growth of pea plants. She puts the same number of seeds into three
identical pots with the same kind and amount of soil. She then gives them
the same amount of water every three days for the length of the experiment.
One pot is placed into a dark windowless closet. Another pot is left on the
windowsill, and the third is placed under a lamp with a green bulb. She
records the height of each plant every day for three months. What is the
independent variable in this experiment?
a. the amount of soil in the pot
b. the color of the light given to the plant
c. the amount of water given to the plant
d. the amount of time the experiment was conducted.

A Fair Test happens when only one factor or variable is changed and all other
conditions are kept the same.
A variable is a factor that can affect the result of the experiment. The three
kinds of variables must be identified in an experiment: the independent/ manipulated,
the dependent/responding, and the controlled/constant variables.
All the variables are kept constant except the one you are testing.
Constant Variable - the factors that are kept the same . (Plants A & B are both
given the same amount of light, water, and are stored at the same temperature.)
Independent Variable - the factor you change, what you do to your experimental
group. Plant A is given Miracle Grow. (Miracle Grow)
Dependent Variable - what happens as a result of that treatment, what you are
measuring (height of plant)
d. Collect and Analyze Data: Observe and record when one variable is
manipulated or changed. It also includes organizing data into tables and graphs so
that it will be easier to visualize the results.
Be careful here, scientists usually don't use the word "prove" because there
are no absolutes in science. In science, every conclusion must assume that the
10
conclusion is only "true to the best of our knowledge". This is an important distinction
between science and other subjects. Science is subject to change when new
evidence is found. And while experimentation and observations can provide strong
evidence for a conclusion, it is not absolute proof.
f. Communicate the result: Present the outcome of the research to the audience.
E What is more
Activity 1: Which is which!
Direction: Read the following sentences and identify the step of scientific method is
employed in it.
Scenario: John watches his grandmother bake bread. He ask his grandmother
what makes the bread rise. She explains that yeast releases a gas as
it feeds on sugar.
____________1. After talking with his teacher and conducting further research, he
comes up with a prediction. “If more sugar is added, then the bread
will rise higher.”
____________2. John wonders if the amount of sugar used in the recipe will affect
the size of the bread loaf? John researches the areas of baking and
fermentation and tries to come up with a way to test his question. He
keeps all of his information on this topic in a journal.
____________3. John comes up with a table he can use to record his data. John
gets all his materials together and carries out his experiment.
____________4. John finds that 70g of sugar produces the largest loaf. His
hypothesis is accepted.
11
____________5. John tells his grandmother about his findings and prepares to
present his project in Science class.
____________6. John writes out his procedure for his experiment along with a
materials list in his journal. He has both of these checked by his
teacher where she checks for any safety concerns.
