stars.
-Based on the video presentation

who can tell me what will be our
topic for today?
-(The pupils will read the objectives)

B. Lesson Proper

-Our topic for today will be all about
the life cycle of a star.
-(The teacher will let the pupils to
read the objectives)
b. Discussion
-I will divide you into 3 groups
-Each Group will be given a short
detailed about the topic for
references, pictures, manila paper,
and a marker.
-Yes/None Teacher
TASK
 Discuss the life cycle of a star
within your group for 10 minutes.
 Each group will be given 5
minutes to finalize and write their
answers on a manila paper.
 Choose a leader and a secretary
 I will pick randomly to report your
output
-Are there any clarification?

Smaller stars or
Average Star,
however, will last for
several billion years, because they burn
their fuel much more slowly.
Stage 3.
Over time, Average stars
will expand, cool and
change colour to become red giants.
Massive stars will turn into

a Red Supergiant.
Stage 4.
Small stars, like the sun,
will undergo a relatively
peaceful and beautiful
death that sees them
pass through a
planetary nebula phase
Massive stars, will turn into a Red

Supergiant, and will experience a most
energetic and violent end, which will see
their remains scattered about the cosmos
in an enormous explosion, called a
supernova.
Stage 5.

nebula phase of a Red Giant stars and

cools down over time and stops glowing to
become a so-called “black dwarf”
Once the dust clears, the

only thing remaining will
be a very dense star
known as a neutron star. These can often
be rapidly spinning and are known as
pulsars. If the star which explodes is
