Environmental science fair projects explore the reasons behind the shocking headlines...
Global WarmingIf you want to study global warming then there are many subjects you can focus on. One of the most common subjects to study is greenhouse gases. Objectives/GoalsSee which of the most common greenhouse gases is effected most to light by increasing the temperature of the earth. Methods/MaterialsMaterial: 1. Glass container 2. 2 lamps 3. Methane 4.Water Vapor 5. Carbon Dioxide 6. Thermometer
7. Hose. Resultscorbon dioxide and methane absorb more heat than any other greenhousse gas in the earth. Conclusions/DiscussionVI. Discussion and Conclusion: I found out that Carbon Dioxide absorbs more heat than Methane, the differences between this two gases was between 66% to 90% significantly in the standard Deviation, different from air and water Vapor, which overlap and demonstrated to have not much effect to heat by not increasing the temperature, but just maintaining it balance. When liquid water is evaporated to form Water Vapor it helps to cool the surface of the earth, and it keeps the air warm enough to support life, this was prove with the results I got in my data by water Vapor being lower than air. Methane and Carbon dioxide had a bigger reaction to light, by absorbing the heat, and demonstrating that they do increase the temperature of earth surface significantly. Carbon Dioxide has the majority of distribution on earth's atmosphere with 76% and methane with 16%. In the study that I did to test which greenhouse gas had more effect to heat, I got as a result Carbon Dioxide following by Methane, a result that is different to my hypothesis. Carbon Dioxide is an important gas because it transmits visible light but absorbs strongly in the infrared. 3rd party contributor
