Circadian Rhythms: Experiment
Circadian Rhythms: Experiment
Circadian Rhythms are the times of day that you get either hungry, tired,
or energetic. This paper is to describe an experiment that I have thought up

people. I will then give each of them a journal. In this journal each subject
will write in it the time that they become hungry, or the time that they became
tired. They will do this for three days. At the end of the three days they
will come back to my laboratory. They will then be put in an isolation booths.
In one of the booths there will be a clock that doesn't have the right time on
it. In another one there will be a window so that they can see where the sun is.
In the third one there will be no windows and no clocks. All they would have is
a light bulb in the ceiling. All the booths will have a bed and a bright red
button on the far wall. The button will be for ringing. They will ring when
they are tired, hungry, or need to use the facilities. My...
