/*******************************************************************************************************/

====Procedure====  
  - Students practice activities normally, then with their thumbs taped.
  - Activities could include tying shoelaces, writing their name, buttoning a shirt, using scissors, using a phone, eating chips etc.

/*******************************************************************************************************/

====Variations==== 
  * Compare human thumb use to how primates without fully opposable thumbs manipulate objects.
  * Determine ways to measure the difference between activities with and without thumbs, such as timing them.

====Safety Precautions====
  * Ensure tape is not wrapped too tightly, to avoid circulation problems.  
  * Dispose of used tape in designated trash bins to avoid litter.  
  * Students should remove tape immediately if they feel discomfort.
  * Ensure scissors are available to help remove the tape quickly if needed.

/*******************************************************************************************************/

====Questions to Consider====
  * Why is the opposable thumb considered an adaptation?  
  * How did the opposable thumb give humans an evolutionary advantage?  
  * What types of tasks are most difficult without using thumbs? Why?  
  * How do other primates use their hands differently from humans?  
  * Could humans function effectively without opposable thumbs? What would change in daily life?
