Regional instructors begin this presentation with a brief review of safety messages delivered in kindergarten, grade 1, and grade 2.
The children are introduced to a rural risk they may never have thought much about – hearing safety. This risk is more intangible than those previously discussed and begins a transition into more situational based presentations where children are taught that personal choices lead to real consequences.
Using ear models, posters, pictures, video clips and animations children are shown how the ear works, how sound travels to the ear and how sound is measured. A sound level meter is used to demonstrate different decibel levels produced by machinery, animals, vehicles etc.
Students are taught that sounds that are too loud, for too long, or too often cause sound induced hearing loss. Children help graph the decibel levels/exposure time/frequency of farm sounds. Students get the opportunity to wear ear protectors and measure sounds with a sound level meter.
Each child receives a take-home safety reminder to help them discuss farm safety with their families.
