FOLLOWUP ACTIVITY
Sleep Latency: Exactly how long does it take you to fall asleep? Write down the time you get into bed. When you are in bed trying to get to sleep, hold a metal spoon over a plate on the floor. When you fall asleep, your muscles will relax and the spoon will fall out of your hand. The noise of the spoon hitting the plate should wake you up. Write down the time you woke up. The difference between the time you got into bed and the time you woke up is your sleep latency.
If the spoon misses the plate, you may not wake up. You could substitute a large metal cookie sheet if this happens.
Materials: Spoon, Plate (or cookie sheet), Clock (or timer)
