Hi Sng4u2,

Oxygen and temperature relates to each other based on projects that involve pressure and heat. First thing first, what are you trying to measure the oxygen level for? Does your project involve heat (such as fire) since you're indicating the "temperature" keyword? Or does your oxygen measurement involve pressure, as well as heat?

Remember, when oxygen is compressed, a temperature can result from the compression.

To answer your question on a general scale, oxygen can be measure using a simple clear plastic tube, marking the tube with in a 1mm, 1cm, or even 1in space. Fill the tube with a water, bend the tube in a U-shape, and what ever oxygen being used up, the water will move according to that distant. Here's an example:

Hope this help.

Ah, the mystery of colors and temperatures. Now, this is a question to ask yourself, and if you think about it carefully, you pretty much finish half of your project questions already:

"Why does the white surface is cooler than the black surface at the peak noon hour?"

To further your research, try look on internet search engine for "light absorption and heat generation"
