I have never heard of any nor do I think any exist. You would essentially do testing for a week, have a week off for Christmas, then collect results the next week/finish off experiments the week after Christmas. Ultimately, you would have a few days to write your paper and present the poster to a school that has nobody there since it would be a break with absolutely no classes going on.
I could be wrong, but this just doesn't seem like enough time to come up with a hypothesis, test, write a meaningful paper, and adequately present your findings to the scientific community. A project that small will probably be completed in the course of another larger experiment during the semester.
