The Background:

   The Turtle was the world's first combat submarine.  It was built by a Connecticut man in 1776, and was sent against a British warship in the harbor of New York City.
   The submarine reached the ship, but the drill bit could not penetrate a copper plate attached to the wooden hull of the British warship.  As a result, the torpedo could not be attached.  (Modern torpedoes are self-propelled, of course.)
   Students should study the drawing, and label the parts of the submarine.  There are articles with more drawings of the Turtle in many encyclopedias - look under submarines, history.  There are also a number of interesting Internet sites with more details about the submarine.
