An airplane requires 3 characteristics to be able to fly in the air:

• the body parts of a bird (pointed cockpit, large wings, light body);
• a proper lifting angle;
• a force which pushes it in the air.

Try to build your own paper plane!

• Use only an A4 paper sheet and your imagination to fold the paper and build a flying plane!

test the airplanes to see how fast, how far and how precise they fly.

You have 3 attempts to throw the paper plane to a target!

Now watch the tutorial clip `How to build a paper airplane?`.

Give feedback to each other, from the improvement perspective, with only constructive critique remarks:

• Step 1. Establish that all of you had a good start: you built paper planes.
• Step 2. Investigate and tell what went wrong: the paper plane didn’t lift enough; it didn’t fly long enough or it didn’t hit the target.
• Step 3. Establish what is to be done to improve the model: a better folding technique; a much pointier cockpit; a higher force to be applied when throwing the plane to the target point.

You have 5 minutes to improve your planes and test them one more time!
