Sensitivity in our body

In the subject of Science, in 3rd grade, we did a little experiment to see how sensitive is our skin depending on each part of our body. We used a feather and whe put a blindfold on our eyes to feel it better, so to decide if the different parts were very sensitive or less sensitive. The kids had a great time and they could learn that our body can be more or less sensitive depending on the part we touch.
