Abstract:
This is an interesting experiment en light of the changing and extreme climate conditions that we have been recently experiencing. According to National Geographic, earth is showing many signs of worldwide climate change: the average temperate is rising 1.4 degree F., the rate of warming is increasing, the Arctic, the glaciers are melting, the coral reefs are dying and the extreme weathers are increasing like wildfires, heat waves and strong tropical storms.( National Geographic ) In our experiment we made a beaker represent our earth and the plastic wrap represented the ozone layer that protects our sun and the sun lamps represented the heat from the sun. Our result found that the plastic wrap did contain the heat. the temperature in the saran wrap stayed consistently the higher

Problem:
What conditions causes the warming of the atmosphere?
What conditions causes the warming of the atmosphere?
Hypothesis: If the beaker is covered in saran wrap then the temperature will increase.
Control group: beaker without saran wrap (beaker a)
Experiment group: Beaker with saran wrap (beaker b)
Independent variable: Heat
Dependent Variable: Temperature
Experiment group: Beaker with saran wrap (beaker b)
Independent variable: Heat
Dependent Variable: Temperature
Materials:
- Ring stand
- sun lamp
- 2 thermometers
- 2 large beakers
- saran wrap
- Timer
Methods:
- Gather materials
- Set up lamp on ring stand
- Place the two thermometers in the beakers
- Place saran wrap over one of the beakers
- Place the two beakers under the sun lamp
- Turn on the lamp and let the beakers heat up for 10 minutes
- Turn off the lamp and let the beakers stand and set the timer for 1 minute
- Record the temperatures every minute for 5 minutes.
Conclusion:
Our results were allied with our hypothesis. Beaker A, our control, cooled down much faster than beaker B. We concluded that the molecules in beaker B, due to the saran wrap covering, were full of kinetic energy and they couldn't spread out so they just kept bouncing off each other. Conversely, in beaker A the molecules could spread out, which allowed it to cool down at a much faster rate. Therefore, we extrapolated that the ozone layer in out atmosphere is like a barrier combined with the sun that causes the warming of our atmosphere.

Data analysis:
Beaker B clearly proved that the saran wrap did contain the heat. Throughout the 5 minutes of consistently checking, we noted the sharp decrease in temperature in beaker A that stabilized at room temperature. At the same time, beaker B only lost heat at a very slow rate throughout the 5 minutes. This is how it worked.
