The document outlines a lesson plan for students to learn about famous Filipino and foreign scientists and their inventions, emphasizing the significance of scientific contributions to daily life. Activities include identifying materials invented by scientists, reading poems and stories, and discussing the impact of these inventions, such as video phones and fluorescent lamps. The lesson aims to encourage students to research and reflect on the importance of scientific innovations in their community.

1. QUARTER 1 WEEK 1
SCIENCE 4
• Use information from secondary
sources to identify a famous Filipino
and/or foreign scientist and their
invention/s.
• Use information from home or local
community to identify a science
invention and explain its impact on
their everyday life.

2. DAY 1
Learning Objectives:
At the end of the lesson, the
learners should be able to identify
famous Filipino and or foreign
scientist and their inventions.

3. Nowadays, people use sophisticated
materials to make work easier and
faster. Materials we use at home, in
school and in the local community are
invented and created by scientists.

4. Cite materials you use at home, at school and in the local community
and classify them as to food, health, cleaning agents or gadget. Write
your answer on your paper.

5. Most of the materials we
see and use at home, in
school and in the local
community are products
of scientists’
inventions.

6. Read the poem titled “I am a Scientist” by Brian Crawford.
I Am a Scientist
by Brian Crawford
I am a scientist. What do I do? I study the nature of things,
old and new. I take a close look at the things that I see And
make guesses about all the ways they might be.
When I find something neat, sometimes I will ponder, “Why
does that thing behave like that, I wonder?” I’ll come up
with ideas – I’ll take a good guess, And I’ll call my guess a
“hypothesis”.
The next thing I’ll do is conduct a short test To see what
answers my question best.

7. When I find a result that explains the confusion I’ll
call that answer my “conclusion”.
Next I’ll write down all the things I’ve uncovered
Then share with the world those neat things I’ve
discovered. And I’ll say to myself when my hard
work is done, “Science is interesting, useful, and
fun!”

8. Questions:
Based on the poem, describe the work of a
scientist.
What are the scientific processes that a scientist
does before discovering something?
What should be the attitude of a scientist?

9. Local and Foreign Scientists:
1. Gregorio Y. Zara. He is a Filipino engineer and
physicist. He was born in 1902 in Lipa, Batangas.
Throughout his work, Zara invented thirty devices. These
devices made life easier for people. He invented devices
that use energy from the sun where electric wires could
not reach people. These are called solar devices. He also
invented a compass that airplane pilots still use today.
Compasses tell you which way you are going so that you
don’t get lost. One of Zara’s biggest inventions was the
video phone.

10. 2. Agapito Flores.
He is the inventor of
fluorescent lamp which is
used at home, schools and
offices.

11. 3. Narciso Mosuela. A
farmer who invented the
superkalan which is
used for cooking.

12. 4. Lawrence Luellen. He
discovered the disposable
cup with lid in 1907 which
is commonly used during
parties and events.

13. The learners will be grouped into
five (5). Each group will be given a
tablet and let them search 5
Filipino and foreign scientists and
enumerate their inventions.

14. Has this lesson helped you to
identify Foreign and Filipino
scientists and their inventions?
Why? Why not?

15. Match the scientist in column A to his invention in column B.
