Music and Sleep
The hypothesis that children fall asleep more quickly with classical music played in the background, in comparison to sentimental music, is proven to be true.
This science fair project can be repeated by varying the type of music being played. Determine if there is a particular tempo or BPM (beats per minute) which children find to be the most soothing.
Besides the genre of music, does the type of instrument that is featured in the music affect our results? Would there be a difference between instrumental music and songs with vocals?
Repeat the experiment with children or even adults of different age groups.
