2. Learning Objectives:
Understand the basic concept of the big bang
theory and other theories that
give clear explanation about the formation of
the universe.
• Explain the evidence supporting the big bang
theory and other theories
5. 1. Based on the videoclip how do
scientists think our universe was created
and what evidence supports it?
6. Collaborative: Big Bang Activity
Introduction: We will compare an
expanding balloon to the Big Bang
and attempt to explain the
beginning of the Universe.
8. Procedure
1. Partially inflate the balloon.
2. Fold and clip it shut with the clothespin so
the air does not escape
3. Draw six evenly spaced dots on the
balloon with the marker.
4. Label the dots A through F
5. Using the ruler, measure the distance in
mm, from Dot A to each of the other dots
9. Procedure
6. Record your measurement in Table 1
under initial measurements.
7. Remove the clothespin and inflate the
balloon some more.
8. Observe what happens to the dots.
9. Pin the balloon closed and measure the
distance from Dot A to each other dots.
10. Procedure
10. Record your data in Table 1 under Trial
number 1
11. Repeat steps 7-10 two more times.
11. Presenting the Data

12. Questions;
1. Based on the activity, how did the universe
evolve according to the big bang theory?
2. If each dot represent a group of starts, describe
the motion of these groups relative to one
another.
3. Based on your model, is the Universe
expanding, contracting or staying the same?
4. What are some of the advantages and
disadvantages of using your model to study the
Big bang Theory?
5. What alternative theories could explain what
you modeled?
13. Group Reporting
Group 1. Creation Myths
Group 2. Big Bang Theory
Group 3. Steady State Theory
Group 4. Inflation Theory
Group 5. String Theory

Organization
Smooth flow of presentation
The presentation
was well
organized, well
prepared and easy
to follow.

not as engaging as
it could have been
for the class.

not consistent with
the level of
confidence/
preparedness they
showed the
classroom but had
some strong
moments

unconfident and
demonstrated little
evidence of
planning prior to
presentation.

15. Inquiry Lab
• If you are to formulate your
own theory about the origin of
the universe, how would you
explain it? What you would call
it?
16. Let’s Wrap it Up
• Write 3 things that you learned.
• 1 thing that you are not sure
about needs more explanation
• 1 question about the topic
