__ Loud Noise __
Do mealworms respond to loud noises and if so, in what way?

**//Hypothesis://** The mealworms will curl up and/or move away from the source of loud noise.

**//Prediction://** Mealworms are sensitive to movement (in this case, vibrations) so they will try to get away from the source of the loud noise.

**//Materials://** Music (with bass preferably)

**//Procedure://** Mealworms were placed on the cover of their container for easy viewing. When mealworms were settled and not moving, music was gradually increased in loudness over the course of a song (about 3 minutes). The mealworms were observed to see if they would react to the music, more specifically, the bass as the music grew louder.

**//Controlled variables://** Temperature, time, location (box)

**//Responding Variables://** Behaviour of the mealworms to the music

**//Manipulated variable://** Loudness of the music

**//Observations://** The mealworms did not react to the music at lower levels but seemed to start moving around as the loudness and bass of the music was increased.

**//Conclusions/comments://** It seems that the mealworms reacted to the vibrations caused the increasing sound and bass but did not respond solely to the music played at a reasonable level.
