Sleepwalking will most likely occur during which part of the night?

Sleepwalking will mostly occur in the non_REM stage of sleep. These are stages 3 and 4 of the sleep cycle. Most often sleepwalking occurs early in the night. Occasionally, sleepwalking happens in REM sleep close to early morning. Sleepwalking is most common in children 6 to 12 years old.

well first you need the sample of the temperature and gas level. i couldnt write a hypothesis unless i had some data. i think temperature changes will effect volumes of gas because gas changed into a solid or liquid at specific temperatures.
