A teacher gave her class of second graders a lesson on the magnet and what it does. 

The next day in a written test, she included this question: 

"My full name has six letters. 

The first one is M. I am strong and attractive. I pick up things. 

What am I?" 

When the test papers were turned in, the teacher was astonished to find that almost 50 percent of the students answered the question with the word "Mother."
