Investigating Sleep

In this activity about sleep rhythms (on page 25 of the PDF), learners will investigate how changing the time they go to bed impacts their own sleep patterns. For one night, learners will go to bed one hour earlier than usual. They will observe and record any impacts that this change has on their abilities to fall asleep, and on their usual wake times the next morning. This lesson guide includes background information, setup and management tips, extensions and a handout.
