A SIMULATION
OF GLOBAL
WARMING

2. ENGAGE

3. Overview
Place with normal Place with high
temperature temperature

4. PROBLEM STATEMENT
 Why are the temperature at
certain places are hotter than
the other places?
 What is the major factor that
lead to this situation?

5. EMPOWER

6. This experiment was taken from :
http://www.fi.edu/guide/otoole/datalogging.html

7. Conducting the Experiment
Equipment and materials:
• Data logger connected to a PC or a graphical calculator
• Two temperature probes
• Two plastic pop (soda) bottles
• Two clamp stands, bosses and clamps
• Carbon dioxide gas (made from marble chips react with
HCL)
• Two heat lamps or flexible spotlights (at least 60W)
• Modeling clay ( e.gPlasticine TM)

8. Procedure:
1. A plastic pop bottle is filled with Carbon Dioxide gas.(The
Carbon Dioxide gas is generated by marble chips reacted
with HCL).
2. Another plastic pop bottle with the same size and
characteristic is filled with air.
3. Both plastic pop bottle is then closed with its plugs.
4. The apparatus is set as figure below.
5. The temperature probes is inserted into both plastic bottle
and connected to computer for data collecting.
6. Heat lamps is placed towards the bottle as a source of
sunlight.
7. The time starts as the heat lamps is switched on.
8. The data from the temperature probe that connected to the
computer is then collected and analyzed.

10. Result and Discussions
• Graph of Temperature vs Time fo Carbon dioxide (pink) and
air (blue).

11. • From the experiment we can see that carbon dioxide temperature is
higher than normal air temperature starting from time equal 12s.At this
time its temperature is higher 0.5 oC than normal air temperature. This
difference can only be seen by using electronic measuring devices like
temperature probe that can give data to a very specific and accurate
value.
• Carbon Dioxide has been identified as one of the atmospheric gases that
allow the sun's energy to pass through it but tends to prevent heat
escaping. When light from the lamp enter the bottle filled with carbon
dioxide the radiation is trapped, it is absorbed by the double bonds of
carbon dioxide molecules, which transfer the radiation to kinetic energy as
the bonds stretch and vibrate. The energy is then re-emitted at heat
energy, which causes the atmosphere in the bottle to warm up.
• It is normal for a certain amount of carbon to be in the atmosphere.
Carbon and other atoms are in the atmosphere above the earth and help
to insulate it to a temperature that is hospitable to life.But excess amount
CO2 lead to Green house effect problem.

12. ENHANCE

13. Application in daily life
how to reduce carbon dioxide level in atmosphere
ventilate our
home naturally
renewable energy stop burning fossil
create awareness
among the
plant more trees
society
Individual
awareness

14. Unique features
shows us that the major factor that can
leads to global warming problem which
is an excess
Measurements are always taken at the
right time
graphs of temperature against time for
the carbon dioxide can be plotted
directly
Have some manipulated variables to get
variety of data.
