Question

how would the student test the hypothesis that the human body maintains a healthy temperature by shivering when it is cold and what data would she collect?
hypothesis: the human body maintains a healthy temperature by shivering when it is cold.
test:
data to collect:
air temperature
body temperature
participants level of comfort
visual observations of shivering
measure and compare body temperature changes to air temperature changes
measure and compare air temperature changes to presence or absence of shivering
measure and compare body temperature changes to presence or absence of shivering
measure and compare participants level of comfort to presence or absence of shivering

Explanation:

To test the hypothesis, create a controlled environment where air - temperature can be varied. Select a group of participants. Observe and record body temperature using thermometers, note visual signs of shivering, and have participants rate their comfort level. Measure and compare these factors as air - temperature changes.

Answer:

Test: Create a controlled environment with varying air - temperatures, select participants, and observe relevant factors.
Data to collect: Air temperature, body temperature, participants' level of comfort, visual observations of shivering.
