### Robotics

Introduction to the engineering design process via paper airplanes

Start of class
• Do Now: Average the following sets of numbers.
• { 1, 2, 3, 4, 5}  3
• {5, 10, 10, 15, 15, 20}  12.5
• {8, 4, 5, 9}  6.5
Today’s learning objectives
• Introduction of the engineering design process.
• “ABCDE” is our mnemonic for the engineering design process.
• Use “ABCDE” to design a paper airplane which flies as far as possible
What does ABCDE mean?
• A = Analyze
• What are we doing?
• B = Brainstorm
• Think of different ways to do it
• C = Choose
• Select a design
• D = Do
• Make a prototype
• E = Evaluate
• How did it work? Can it be improved?

And keep refining your solution until it’s as good as it can be!

Paper Airplane Challenge
• In groups of 2 or 3, make a paper airplane that will fly as far as possible.
• Distance is measured perpendicular to the direction of the throw. Curves and diagonals do not count!

WINNER!

• Three sheets of paper.
• Three paperclips.
• No replacements will be issued. If you “mess up” some of your materials, you will need to do without them.
• Part of the challenge is the restricted material supply!
• You may cut and fold the paper as you like.
The steps to follow…
• Choose a first airplane design. Throw it three times, record the distances, and calculate the average distance.
• Then make a guess about what might make the plane fly better. You may change whatever you like, but only change ONE THING. This is your “hypothesis.”
• Record what change you made. Then again throw the plane three times and calculate the average distance.
• Repeat this process
Homework
• Write at least half a page explaining today’s experiment. (Use pictures, if it helps to explain) Be sure to include:
• Who you were working with, and what each person did.
• What changes you made to the first airplane.
• Which change made the biggest difference.
• How might somebody make an airplane that flies even farther?
End of class
• Put your airplanes in the table folders
• Put your data sheets in the table folders
• Please put the chairs up
