Smell that? Its another "What do you guys think?" questionATLANTA, Aug. 16--A rose is not just a rose these days. In some schools, it's also a scent that goes straight through the schnozz and keeps kids from snoozing and schmoozing. Mozart's sonatas help kids learn, too, and rap makes their neurons snap. Peppermints also stimulate young brains; so does water.
"Brain-based learning" is all the New Age rage as the 2000-01 school year gets under way. The idea: Scents, sweets, sounds, colors, lighting, water and other inputs produce various responses in young brains, and can be orchestrated to make them more receptive to learning.
The research behind the theory is not all rock-solid, and the state Department of Education doesn't take a position on it. Yet hundreds of metro teachers are convinced, and some schools and school systems offer seminars to instruct educators in the methods.
Among the stimuli being used in classrooms: peppermint candy (sugar and mint to invigorate); water bottles (to hydrate); aromatherapy (to rouse or calm, depending on the scent); dim lighting (to calm and focus); music (ditto) and walls painted in subdued colors (ditto).

Yes this is old however, all my teachers say the same thing (thats where the tip came from)
