Global Warming in a Jar

This is very clever global warming experiment developed by a young student for a local science fair. The film is presented by the Cleveland Museum of Natural History and the Clean Air Conservancy.

Thank you for your comment. This fourth grader came up with it himself for a science fair and we were so impressed by the elegant simplicity, we had to share it.

He should of done a jar with water vapor in it, another with Nitrous oxide.

Bravo, young 'un.

The switch was right next to the jar A (the jar with CO2 in it). The switch was probabally really hot so the heat tranfered to jar A.

How much were the C02 levels raised, and how much did the temperature increase. I think this would be an excellent experiment to try to see if the correlation is linear. It does demonstrate that C02 holds temperature longer, but C02 is also denser than air. These are the kind of tests the government should be preforming before they enact carbon taxes. I want solid proof before I give up my money. I'll still use neon bulbs and turn off the lights when I leave a room!

I applaud your experiment because it seems impossible to find any professional academic experimental proof of the "greenhouse effect" nor the equations to quantify it . However you must know that there are many problems with your methods which make it nothing more than a show piece to please the adults around you .

excuse me, is this supposed to be beyond criticism? is that why my first comment didn't appear after 'pending approval'?

[stupidtreehugger]

Excellent! Now try again with the 0.000076% CO2 jar (current normal air) and the other one with a couple of hundred parts CO2 more per million rather than 100%. And then chuck a plant in there and see what happens - 90% of a plant e.g. a log of wood is C from CO2. Are you not practicing Ronald McDonald Science? Inculcation and Exploitation through oversimplification?

Very well done, well explained, simple yet effective. It is so good, I'd like to use it to explain both the Greenhouse Effect and Global Warming to people who haven't had much exposure to the mechanism behind these effects.
