Instructional Ideas

• Add the resource to an integumentary system unit
• Observe the class as they watch the video and keep track of the number of pupils that itch while they watch; use your observations to start a discussion about the urge to itch or yawn when someone else does

Classroom Considerations

• Review some basic integumentary system components before watching the video
  

• This video is hosted on YouTube

Pros

• The narrator explains neurochemical processes using simple terms to help learners understand
• Video includes good reasons for itching, such as removing harmful substances or organisms from skin
  

Cons
