Subject: do sucking on peppermints, while taking a test, increase test scores?

I am doing my science fair project on this. I have given a group of 5 
students(5th gr)5 tests of 10 math questions each and they did not suck on 
mints. i then gave them 5 more tests and they sucked on the mints while 
taking the test. the scores of the test while the sucked on the mints were 
a little higher then the non-sucking tests. somewhere out there this has 
been tested and i can not find any of the research.  my teacher said that 
this has been proven just with in the last year or so. my teacher in 5th 
grade made us suck on peppermints and that is why i wanted to do this 
experiment. Thanks for any help you can give me.
