Product Description

In this lab activity, students will learn:

  • How the reflex arc, or pathway, of the simple withdrawal reflex and the last and automatic reaction to a stimulus is a reflex action work and prevent injury to the body. For example, the withdrawal reflex that allows you to remove your hand from a hot stove before you even feel a sensation of heat helps to prevent a severe burn.
  • How reflexes also control automatic activities in the body, such as the beating of the heart, breathing, gagging, and stomach movements.
  • The time required for the brain to receive the impulses, interpret them, and initiate a response is much longer than the time required for a reflex arc involving only the spinal cord.
  • Measure reaction time, the measure of how quickly he or she can perceive a stimulus and react to it and how fatigue, drugs, and distraction effect it.

The only materials need for this lab include:

  • Hand or rubber reflex hammer, clear plastic sheet, meter stick, calculator with square root function or a table of square roots

I love how easy this lab is to do and how much my students always enjoy it.
