For a possible science fair experiment, I might do something about how long a light bulb will last. However, this experiment is due in a very short amount of time, so I was wondering if anyone knew of a light bulb that lasts for a short period of time? Around maybe 1 month?

A month is 720 hours. Ordinary incandescent bulbs are the shortest-lived bulbs that are readily available, and they tend to have advertised life expectancy of 1500 hours or more.
However, if there is a reasonably stocked photography store in your area, you can ask about photo floods. These are special incandescent bulbs that are intended for photographic purposes so they produce a lot of light (and heat) and the power input rating is much higher than ordinary household bulbs. They are a bit more expensive that ordinary bulbs, but the advantage for you is that their life expectancy is much shorter than ordinary household bulbs.
