The document discusses several theories about the origin of the universe, focusing on explaining the Big Bang theory. This theory proposes that the universe began around 14 billion years ago from an infinitely tiny, dense point known as a singularity, and has been expanding ever since. Key evidence for the Big Bang theory includes Hubble's law, which describes that galaxies appear to be moving away from Earth and the farther away they are the faster they recede.

2. It's nice to see
you all today!

3. LEARNING OBJECTIVES:
At the end of the lesson and in
the long run, the students
should be able to explain the
different theories of the
universe's origin using a simple
diagram.

4. ESSENTIAL QUESTION:
What is the universe and
how did it begin?

5. Share what you know:
What are the objects that can be
found in the outer space?

6. Completing the Concept Map:
There are empty boxes in the
concept map on the next slide. Your
task is to fill in the boxes with
appropriate words.

9. Humans use religion,
traditions, philosophy, and
science to describe the
origin and structure of the
universe.

10. GENESIS
One of the books from
Hebrew Bible and Christian
Old Testament.

11. In the beginning, God created the heavens and
the earth. The earth was without form and void,
and darkness was over the face of the deep.
And the Spirit of God was hovering over the face
of the waters. And God said, “Let there be light,”
and there was light.
~ Genesis 1 English Standard Version (ESV)

12. CREATIONIST THEORY
God, the Supreme Being,
created the whole universe
out of nothing.

14. BIGBANG
THEORY

15. BIGBANG THEORY
This is the currently accepted
model of the formation of the
universe.
This theory is attributed to the
Belgian Roman catholic priest
Georges Lemaitre in 1927.

16. Matter did not
exist at the
beginning of
time; there was
only pure energy.
BIGBANG THEORY

17. BIGBANG THEORY
This theory describes that the
universe is EXPANDING, having
originated from an infinitely tiny,
infinitely dense point around 14
billion years ago.

18. BIGBANG THEORY
The single point mentioned in this
theory wherein the universe
originated from is known as
SINGULARITY.
"infinitely tiny, infinitely dense point"

19. BIGBANG THEORY
Credited to Edwin Hubble
One of the supporting shreds
of evidence of the Big Bang
Theory
HUBBLE’S LAW

20. BIGBANG THEORY
It explains that galaxies appear
to be moving away from the
earth.
The speed of the movement is
proportional to galaxies' distance.
HUBBLE’S LAW

21. BIGBANG THEORY
The concept of redshift and
the doppler effect can be
used as evidence for
Hubble's law.
HUBBLE’S LAW

22. BIGBANG THEORY
When the source of the light is
moving away from the observer,
the frequency of the light
observed is shifted toward the
color red.

23. ACTIVITY:
On a yellow pad paper, create a
simple diagram that would
summarize the Big Bang theory's
explanation of how the universe
was made.
