I've got a science fair project coming up. im going to make two greenhouses (because they look cool and will pull in a better grade) and fill one with CO2 to see if it gets hotter in the sun than the other without CO2. my mom says i should just use stupid tubes because they would make it easier and i would get a better result. so what should i do, have fun makeing the greenhouses and maybe not get the most perfect result, or get the clear result with a boring project?

Several things to keep in mind.
Is Mom providing the supplies or money to buy supplies to do the project. No reason to make it hard on you if she's supplying the materials. Do what she thinks.
If you're supplying your own matierals then I suggest you get her permission to build the greenhouses so that you are more interested and engaged in what you are doing.
Science Fair projects should be interesting and show a scientific mind. Make sure you get lots of data, and produce lots of graphs. Remember that you're doing SCIENCE not building construction, so your project should show LOTS of data and a thorough analysis of the data.
Good Luck!
P.S. If Mom isn't happy, ain't nobody happy, so I'd be very careful ever making mom mad. Ya know? (smile)

You're sort of on the wrong track here. I suspect you're interested in CO2 because you think that CO2 has something to do with global warming, and if you put that into a greenhouse you'll figure out something. So, I hate to tell you this, but your experiment won't work no matter how you build it. The effect you would be looking for will be so small on the scale you are talking about that you'll never find it. What was your hypothesis? Do you think that it will be warmer with CO2 inside, and why do you think so? Start with that.
You might have more fun if you changed the color of the glass, or put something inside to "soak up" the heat, like some large rocks, or even a can of water.

It's your project and your grade, not your mom's, but think about this, if it's a greenhouse and it grows plants and plants disperse CO2 then how will you not have CO2 in the second greenhouse?

You should do some research before you build anything.
Why do you expect that they will have different temperatures?
How will the material you choose for the walls effect the results?
How are you going to measure the temperatures?
How are you going to make them air tight?
note: I suspect that the gas in the enclosure will not produce a measurable difference in temperature because the walls and thermometer will dominate the results.
