2. 90 minute Sleep Cycle

Highlight important and interesting points as you read through

Once you’ve read through - In your journals, summarize the Circadian Rhythm in your own words and include the following info:

1. What is the Circadian Rhythm

In your journal – write the title: My 24 hour clock Reflection

Reflect and compare the Circadian Rhythm 24 hour clock in the diagram to your own personal 24 hour clock.

Some things to think about…

• Does your body’s physiological activities line up with those of the diagram? (which do and which do not?)

• For the body activities that differ from those in the diagram – at what times in the day do you experience these?

• Are there any factors that you think could affect your body’s 24 hour clock?

• Any other thoughts???

Circadian Rhythm Assignment

PART 1 – Your Ideal 24-hour Schedule it must contain all activities that you currently do and the duration of those activitiesIe. If you are in 3 blocks at school that are 90 minutes each – you must allot this time throughout your daily schedule however you would like.

Other examples: Work, Working out, Sports, Clubs etc.

PART 2 – Your Ideal 24-hour Circadian Rhythm Timeline In the computer lab on Monday – use a Free Timeline Program to Create your ideal Circadian Rhythm Timeline.

This should include the physiological processes and activities that you experience throughout the day. These processes/activities should coordinate with your schedule from PART 1

Sleep Schedules Summary 1. Monophasic (most popular)• Consists of sleeping once a day (approx.7-9 hours)• Not the best sleep schedule – however most convenient for most
