Take The Mr Potato Pieces (Arms, Nose, Eyes, Mouth, and Hands) and put them in a container the children can not see in (a bag or feely can etc...) The children then pick one piece out and tell the group what sense is used in regard to the particular body part. I have also played this by putting the pieces under a parachute and the child has to climb under the parachute to get one "sense" organ and return with it.
