Jamie was co-host
of the Science Fair TV programme and explained in detail how her classroom
noise level indicator/alarm system works.
She was too
young to enter this project in the 2003 Bright Sparks Hi-Tech
competition...a shame since her teacher has loved using it in class.
have created a device designed to help people such as teachers or
librarians to monitor noise levels.
Bell Block school there is a 'traffic light' sound system. My
innovation mimics this system. When the teacher requires the class to
be silent, she puts up the red light. When she requires the class to
whisper, she puts up the orange light. When there is a fun activity,
she puts up the green light. So, students can know what noise levels
are expected. I decided to take this one step further and make it
electronic where it can sense the noise level and warn the class by
beeping when it is too high for the set level.
It is efficient as a teaching tool because
it helps the teacher to know
when the classroom gets too noisy. A remote control is used to save the
teacher having to get up from their desk all the time. It is versatile
and an excellent teachers tool and could be used in any school
My sound sensor is useful in the classroom
because the teacher can
monitor the sound out of the classroom. The class is also alerted when
the noise level is too high by the beeper. When the teacher sets the
noise level on the traffic lights (red: quiet, amber: whisper, green:
noisy) the beeper will beep if the class exceeds the set sound level.
teacher has used this in our class since the Science Fair in August and
thinks all teachers should have one.
Thank you Mummy for helping me with the
writing and thank you Daddy for
helping me with the project.
