Paper airplanes are really gliders that glide on air.  There shape is aerodynamic, which means it allows air to pass around it easily.  The more air that can pass around your shape, the faster your shape will travel.

Did you know that in some countries, airplane is spelt aeroplane?

Paper airplanes are easy to build and easy to fly!  Here is a famous model:

The Bulldog Dart.

How to make the Bulldog Dart

Take a piece of rectangular shaped paper, and fold it in half length ways

Unfold the piece of paper, and you will see you have a fold, like a line right down the middle.  Taking one of the top corners, and fold it so that it meets the fold in the middle.  This should make a triangle shape.

.

Once this is done, do the same with the other side so that it looks like the picture below.  As you can see, it looks like a house.

.

Turn the piece of paper over, so that you can’t see the flaps.

Carefully fold the piece of paper from the top and the right hand edge so that it meets in the middle.  It should look like this.

Do the same for the left.

Now, fold the point at the top, so that it touches the paper, not too much, about halfway between where the paper meets.  See below

Fold the plane in half length ways, and then rotate it so that it is on its side

.

Take care when doing this next part as it is very easy to make a mistake.  Take the top of the wing, and fold it in half so that it meets the bottom corner.  Make sure you smooth out any creases, and you keep a careful eye on where it is folding at the front of the plane.

Turn the plane over, and do the same for the next wing.

Now straighten the wings, and your Bulldog dart is ready for a test flight.  How does it fly?

How far can you fly your plane?

Have you tried to fly it from the top of the stairs?

Were these instructions easy to follow?  How can they be improved?
