Joseph was ready to go with his experiment materials, lab coat, and goggles.

Experiment:  Pencil Touch Test

Objective:  Discover where the sense of touch is strongest

First, Joseph asked his assistant (Dad) to close his eyes.

He then touched him with 2 pencils on his hand and asked him how many pencils he felt.  When the pencils were far apart, Dad answered, "Two".  Joseph continued to put the pencils closer together and continued to ask the same question.  As the pencils got closer, and Joseph asked again how many pencils he felt, Dad answered, "One".  But the class could clearly see there were 2 pencils touching him! 

Joseph continued the experiment on his dad's arm,...

…back,

…and leg! 

The experiment worked the same way no matter where on his body he performed the experiment! 

Of course, some classmates wanted to participate too!

This is a great experiment to try at home!

Conclusion:

Your sense of touch is strongest in areas where the nerve endings are close together.
