I would like to acknowledge both my parents for working on this project with me. My dad supported this experiment with buying all the necessary equipment and materials. He helped to set up my reflector lamp and keep the used gases under control. My mom helped me with collecting my data, and inputting its importance into my research paper. My mom assisted with more of my background research collecting and my dad with the “hands-on” aspect of my project. The proposed hypothesis predicted that greater amounts of carbon dioxide in a controlled environment would increase the temperature at a higher rate, and the decrease in temperature would be at a lower rate. As carbon dioxide is a denser gas than oxygen, the molecules making up the carbon dioxide are more tightly compact. This lead to the prediction that those particles would be able to hold the heat from the reflector lamp at a higher rate.100% Carbon Dioxide:50/50 Carbon Dioxide and Oxygen:100% Oxygen:My hypothesis predicted multiple things based on each mixture of gases and each grouping of the data. My hypothesis was partially correct, as the increase in temperature contradicted my prediction, while the decrease in temperature proved it correct. My hypothesis was wrong in terms of the increase in temperature of carbon dioxide. The increase in temperature for co2 was slower than the increase of temperature for the air. The carbon dioxide took longer for the heat to rise which made the time of the increase of the temperature longer. My hypothesis was right for the decrease of temperature of the carbon dioxide. The carbon dioxide held more heat resulting in temperature decrease to be longer.This experiment can be used in a real life situation when considering the causes of global warming. When viewing this experiment and its relation to the real world, it is an experiment that represents global warming and real issues in our world today. The results of my experiment are prominent in the field of science through environmental sciences, as studying greenhouse gases and aspects of global environment falls under that branch of science. My results can be used to find a way to efficiently prevent excess amounts of carbon dioxide in the air. My experiment results will be recorded in units of temperature. The range of temperatures will show the effects, of the presence of co2 in the atmosphere. Greenhouse gases are gases in the Earth’s atmosphere that absorb and emit radiation within the infrared range. This process is the fundamental cause of the greenhouse effect. Common greenhouse gases in the Earth’s atmosphere include water vapor, carbon dioxide, methane, nitrous oxide, ozone, and chlorofluorocarbons. Greenhouse gases, mainly water vapor, are essential to helping determine the temperature of the Earth; without them this planet would likely be so cold, as to be uninhabitable. Although many factors such as the sun and the water cycle are responsible for the Earth’s weather and energy balance, if all else was held equal and stable, the planet’s average temperature should be considerably lower without greenhouse gases. Human activities have an impact upon the levels of greenhouse gases in the atmosphere, which has other effects upon the system, with their own possible repercussions. The 2007 assessment report, observed that “changes in atmospheric concentrations of greenhouse gases and aerosols, land cover and solar radiation alter the energy balance of the climate system,” and concluded that “increases in anthropogenic greenhouse gas concentrations is very likely to have caused most of the increases in global average temperatures since the mid-20th century”. When these gases are ranked by their contribution to the greenhouse effect, the most important are: Water vapor, which contributes 36–72%. The second gaseous element is carbon dioxide, which contributes 9–26%. Methane, which contributes 4–9% is the third gas. Lastly, ozone which contributes 3–7%. These are listed in the order of abundance and prominence to the atmosphere.Controlled variable – Amounts of gases, carbon dioxide and oxygen are heated, both in a one cup measurement. Same measurements, same heating lamp, total amount of testing time, and selfsame timed benchmarks for each temperature recording. Independent Variable – Type of gas that goes into every one of my bell jars. There will be a different mixture of gases in every jar. Dependent Variable – The average of all 3 temperature from all 3 jars. The final set of temperatures is the results and the atmospheric gases affect the temperatureObtain Resources/Materials:2. Place thermometer in 100% co2 jar3. Place one cup of carbon dioxide in mason jar; using 237 ml of baking soda and 475 ml of vinegar, and seal it4. Let carbon dioxide sublimate, or until it has gone from liquid to its gaseous form5. Place reflector lamp a ¼ of an inch away from the mason jar6. Turn on reflector lamp and start clock7. Record temperature in log book every 15 minutes8. When thermometer reaches 40 degrees Celsius turn off lamp9. Record temperature every 15 minutes until thermometer reaches 19 degrees Celsius, to measure the rate of decrease in temperature10. Repeat this gas jar’s experiment 3x for clear results.11. For experiment with oxygen, place thermometer in vacuum bell jar.12. Seal the vacuum bell jar13. Repeat steps 5-10, for this jar14.
