  • Student will perform a simulation to measure the sound intensity at different distances from the source of the noise.
  • Students will use the data to develop an inverse variation model. 
  • Students will verifying the model and use it to map safe and unsafe zones based on sound-intensity restrictions.


  • inverse variation
  • direct variation
