5. Lesson Language Practice
I Am a Scientist
by Brian Crawford
Illustrated by Lovely Rollaine B. Cruz
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”.
Read the poem and answer the following questions.

6. Lesson Language Practice
The next thing I’ll do is conduct a short test
To see what answers my question best.
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 hard work is done,
“Science is interesting, useful, and fun!”
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.
Read the poem and answer the following questions.

7. Lesson Language Practice
GUIDE QUESTIONS:
1.What should be the attitude of a
scientist?
Possible Answer: A scientist should be curious, ask
questions, make guesses, test those guesses, and
share what they learn. They should also find science
fun and interesting.

8. Lesson Language Practice
GUIDE QUESTIONS:
2.What are the scientific processes that
scientists do before discovering something?

9. Lesson Language Practice
GUIDE QUESTIONS:
Possible Answers:
1.Observe things closely: "I take a close look at the things that I see."
2.Make guesses, called hypotheses: "And I'll call my guess a 'hypothesis'."
3.Conduct tests to check their guesses: "The next thing I'll do is conduct a
short test."
4.Find results and make conclusions: "I'll call that answer my 'conclusion'."
5.Write down their findings: "Next, I'll write down all the things I've
uncovered."
6.Share their discoveries with others: "Then share with the world those
neat things I've discovered."

10. Lesson Language Practice
GUIDE QUESTIONS:
3. Based on the poem, how do you describe
the work of a scientist?
Possible Answer: Based on the poem "I Am a Scientist" by
Brian Crawford, the work of a scientist is described as a
process of curiosity, exploration, and discovery.

11. Reading the Key Idea/Stem
Read the important passages and answer the questions that follow.
Great Inventors, Inspiring
Inventions

12. Reading the Key Idea/Stem
Gregorio Y. Zara was a Filipino
engineer and physicist born in 1902 in Lipa,
Batangas. Zara invented thirty devices
throughout his career, which made life
easier for people by improving their daily
activities. He invented solar devices that
use energy from the sun which can be
used in places where electric wires could
not reach. He also invented a compass, a
device that pilots still use today for
navigation. One of Zara’s biggest
inventions was the video phone.
