The problem is to build a paper airplane that will fly for the longest time. 
The Design Criteria
The plane can be made only from one sheet of 8 1/2" x 11" recycled copy paper and less than 1/2" of tape.  Your name will be clearly visible on the plane. No other materials, such as paper clips, may be used.
You may work with a partner to complete the problem solving worksheet on page 28 of your notebook.

Then, working alone or with a partner, you will find directions for making a paper airplane.  (Be sure to list your source.)  Make it and test it!  Look for different ideas from the Internet, books, and friends or just invent a new plane yourself.
