The hypothesis is that the children will have a more restful nap with classical music rather than soft rock.

You will record the same children for every video recording, playing the same Mozart music or the same Beatles music. You will measure the children's restful behavior by tallying large body movements.

You will need 8 children, 1 video tape, 1 battery charger, 1 television, 1 The Beatles playlist, 1 Mozart Piano Concertos Nos. 20 & 21 playlist, 1 music player, 8 cots, 1 childcare center, 1 phone or videocam to record video, and 1 tripod or stand for the recorder.

The results of the experiment showed that the trials using classical music had approximately half the restless movements of the soft rock music trials. This indicates that the hypothesis should be accepted.

This science project is interesting because it can help parents and childcares around the world get their children to rest better during the day.

Variations of this experiment could include recording the amount of time that it takes for a child to rest, instead of the amount of movements a child has, or testing adults or teenagers instead of children.
