Abstract:
The Greenhouse House effect is greenhouse gases that cause some radiation from the sun to be trapped as heat in the troposphere. For this lab we were given two types of problems and we would have to choose one problem and try to find an answer. My group choose to try and figure out the speed at which the air heat ups. Four different cups were filled with water and three of them were covered with aluminum and one posed as the control cup. The Four cups would be place under light and we would observe the data on how fast the temperature would increase. The purpose of our lab was to show how global warming keeps all of the heat trapped inside the cup which eventually causes for the temperature to change.
Problem:
How quickly does the warming of the atmosphere occur?
Hypothesis:
All together as group we predicted that the controller cup which is cup D will heat up faster then the cups that are covered with aluminum foil.
Parts of the Experiment:
Control Group- Cup D
Experimental Group- Cups A,B,C
Independent Variable- Temperature
Dependant Variable- Time
Materials:
- Four plastic cups
- Water
- Four thermometers
- One lamp
- Aluminum Foil
- Marker
Methods:
1. Four cups were layed out and filled up half way with water.
2. Cup A was given one layer of aluminum foil.
3. Cup B was then given 2 layers of aluminum foil.
4. Then lastly Cup C was given 4 layers of aluminum foil.
5. Cup D was made the control cup with no cover.
6. A thermometer was then put into each of the cups.
7. All four of the cups were put under a lamp and would be monitored.
8. Every two minutes data was taken on the temperature of the cups.

Analysis and Conclusions specific to the lab:
As said earlier the purpose of the assignment was to show how global warming keeps all of the heat trapped inside. The aluminum foil that was covering the cup was suppose to represent global warming and how it keeps all of the air trapped inside of the atmosphere. Greenhouse gases do not release in anyway from the atmosphere and the earth continues to become hotter as more energy gets brought in. But as were were collecting data the lab was not exactly going as planned. Our idea was that the light from the lamp would hit the aluminum foil and cause for the water to start to warm up and trap all of the heat inside the cup. Instead the heat coming from the lamp reflected off of the aluminum foil. When the heat was rejected it them acted as smog and caused for the temperature of the water to decrease. Not only was the heat rejected but the positioning of the light also had an effect on the results. Some of the cups were receiving more light them others. So while some cups had increasing temperatures, some also had decreasing temperatures or the temperature stayed the same. so that also had a great impacted on the outcome of the assignment.
General Analysis and Conclusions:
Based on the over all observation of the experiment if different steps were taken then it would have worked as planned. When aluminum foil was used the global warming instead of trapping the heat it rejected off of the foil and in return it made smog. If saran wrap was used then the heat from the light would have reflected straight into the water and caused the heat to become trapped just as the greenhouse gases do. The heat would have acted as the radiation that cases the air to become stuck in the atmosphere making earth become hotter and hotter. Then we could have also used more lamps to try an make the amount of heat hitting the saran wrap as equal as possible for better results. But just as said in the article greenhouse gases cause the earths temperatures to increase rapidly. The more greenhouse gases that are brought into the atmosphere the more the temperature will increase. With that being said if things are not done by the year of 2100 the article is predicting that the average global temepertures will increase from 2 degrees Fahrenheit to about 11.5 degrees Fahrenheit. This rapid weather change will have great effects on the environment and us as humans.
