Activity 4A: Lights Out!

Melatonin is a chemical we make in our bodies that helps us sleep. In this kinesthetic activity, students will discover the effects of stimuli, such as light and food, on the release of melatonin. They will also actively “experience” the pathways involved for melatonin release. They will explore how the response to various stimuli can control the regulation of melatonin release and even interfere with getting enough sleep.

  • Describe what melatonin is and what it does in the body
  • Demonstrate the effect light and food have on the release of melatonin
  • Describe a Stimulus/Response reaction
  • Demonstrate the 2 most common pathways that control melatonin release
  • Infer how to better regulate sleep and wake cycles
