This week I was learning to use complex sentences I found it challenging to add complex sentences My digital learning object shows a piece of whriting that shows how planes Next time I would add more complex sentences 

How does a plane fly?

A plane is a powered flying vehicle with wings and they fly because the shape of the planes  wings it's shaped like that to optimise the speed on the runway and especially in the air 

Firstly  because the shape is  aerodynamic, the air flows under the wing easily and  a very small amount  just flies on by on the top . when the plane has enough air under the wing  the plane  gets very light 

Secondly the pilots will put the flaps down to hold more air under the wings so it's very light so light in fact that the whole plane lifts off the runway.

Lastly the plane will stay in the air because the air is denser and also there is a lot more air in the sky than there is on the ground.

so that's how planes fly. I hope you learned something from this.
