Any Help?

[Armageddonman]

I'm doing a project on Climate Change in Science. It is fairly simple i guess. Im taking a sample from the troposhpere and putting it in a bottle. With a couple of more bottles i am putting different levels of CO2 in them. Then a thermometer goes in each and i put a heat lamp on them. Its to see if theres a temperature difference with CO2 retaining more heat.
Any Suggestions for this project or an entirely new Science Pro. Remember keep it at like an 8th or 9th grade level.

Much appreiciated

I would also try water. water vapor is one of the strongest greenhouse gas known today.

Ya i was thinking about that but how would i make that without disrupting the thermometers temperature? I would try other things but having things like pure oxygen and stuff could get a little dangerous

If i would be doing this. i would but make some large box and put an transparent inflatable pool bed filled with the gas over it in an way air cannot get in or out the box. And put the thermometer in that box. i will make two of those boxes.

i fill one of them with normal air as the control experiment. i need this to rule out the greenhouse effects of the box itself. the other one is filled with the gas of choice. this is the experiment itself. I would write down the temperature of each thermometer without opening the box each half hour from dusk till dawn. And subtract the readings from the control experiment from the results of the experiment. The result of this is the effects of the gas on the temperature in the box.

I would leave out the oxygen for safety reasons indeed, but you can easily get carbon dioxide rich air by catching the air above an clean fire. ( One without smoke like those generated by propane burners used for camping).

Ya, i was thinking something along the lines of that. But for the Carbon Dioxide i thought i could get it by using the airsoft or paintball Co2 canisters but i was wondering if those are pure carbon dioxide. are they?

[lycanox]

Could be. But they could also been filled with laughing gas.

Nevermind, i think dry ice is the best solution.
