My Hypothesis

The larger the surface area of a paper plane the more time it will take to hit the floor.

Independent Variable – The surface area of the plane.

Dependant Variable – The time it takes the plane to fall.

Supporting Evidence:

‘Objects with large surface areas, such as parachutes and shuttlecocks fall more slowly because they experience more air resistance.’ – BBC Bitesize

‘Air resistance depends on two important factors – the speed of the object and its surface area. Increasing the surface area of an obect decreases its speed.’ – study.com
