Presentation Transcript

### 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!

Your materials:

- 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
