The document outlines a lesson plan on phase changes of matter. Students will be divided into groups to present on different phase changes through singing, dancing, poetry, or drawing. They will learn about freezing, melting, evaporation, and condensation. The class objectives are to differentiate the four types of phase changes, illustrate how temperature affects particle motion and arrangement, and cite ways to reduce global warming and climate change.

2. PICK
AND
SPEA

3. Arrange the chairs in a
circle. The learners must pass
the box containing the pictures.
The learner who holds the box
when the music stops will pick a
picture. He/she will then
identify the objects, the states
of matter present and describe
the changes occurring in the
sample matter.

4. Clothes hung on a sunny day to dry

5. A cold glass of water

6. Butter in a frying pan

7. Water in plastic taken out of the freezer

8. OBJECTIVES
1.Differentiate the four types of
phase changes.
2.Illustrate the effect of changing
temperature to the arrangement
and motion of particles.
3.Cite ways on how to lessen the
impact of global warming that
to climate change.

9. PHASE CHANGES
OF
MATTER
CLASSROOM OBSERVATION 1

11. Guide Question:
From what you’ve seen in the video,
how did the rising temperature (more
heat) affect the motion and
arrangement of particles? How about
the falling temperature (less heat)?

12. LET’S PHASE IT!
The class will be divided into 4
groups. Each group will have an
indefinite number of learners
since they will accomplish the
task according to their
inclination. The learners must

13. Singing
The learners must choose a
melody of a certain song and they
must make their own lyrics to
describe what happens to the
particles during freezing.

14. Dancing
The learners must
interpret melting
through a dance.

15. Poetry
The learners must make a
poem about evaporation.

16. Drawing
The learners must draw
the particles of matter
during condensation.

17. GROUP PRESENTATION
(Each group will be given 2
minutes for the
presentation. Rubric for
scoring will be posted.)

18. Guide Questions:
 What form of energy is involved in
phase change?
 How does the addition and removal
of heat affect the movement of
particles?
 Does phase change involve changes
in the chemical structure of the
particles? Why do you say so?

25. “MY PLEDGE TO HELP SLOW DOWN GLOBAL
WARMING”
The following are some of the most common environmental
problems caused by global warming. Choose one from the list.
Look for a picture of your chosen environmental problem and
create your own pledge on how you can help lessen the impact.
You may paste the picture in a long bond paper with your
written pledge.
Choose one:
1. Melting of ice glaciers
2. Increased evaporation/great loss of soil moisture (El Niño)
3. Increased condensation (La Niña)
