Physiological and Cultural Adaptations to High Solar Radiation.

 The Scenario: 

You have become increasingly agitated by an occasionally snoring classmate sitting behind you in the back of your lecture hall. The professor has asked the student to come in ready to learn, not nap, on multiple occasions, but to no avail. If I were to conduct an experiment using the scientific method to discover a possible solution for this student's daily need to rest by substantiating the possible reason causing it, it would follow as such:

Hypothesis:

 I hypothesize that the cause of the students' drowsiness is temperature comfortability. More specifically, sitting in the back of the classroom away from vents that would pump cool, awakening air towards him. 

Test: 

- I would test this hypothesis by asking the student to sit in the middle/ front rows, closer to a ceiling vent. I am altering the conditions by changing the individual temperature experience of this student during the duration of the class. 

- If the student remained alert and attentive rather than dozing off once again, my test would have supported my hypothesis.

- If he continued to snooze and snore regardless of the change in temperature due to orientation to the vents above, my hypothesis would have been falsified, as the problem must lie elsewhere. 

An Untestable Explanation:

 If I were to come up with a completely unfalsifiable hypothesis for the sudden sleep onset, I would say that the cause for the student's sleepiness during class is because aliens on a spaceship outside of our galaxy and in a different time zone have cloned the student, replacing him with a genetically identical body and brain, and he sleeps every day at that time because he must power down at the same time his real self does every day.
