Ever heard of a stoplight that controls sound? The Stoplight has a level of noise control and when it gets too loud it blinks yellow as a warning, and when it's too loud for the sound level, it blinks red and the siren goes off. In P.E. class, the consequence is exercises. It really works, because the kids are so paranoid that when it flashes yellow, it will soon flash red and trouble they will be. What a great invention.
We took it from the 2nd Grade, and will soon be buying one for our classes next year.
