=
In my hypothesis I predicted that the box with the larger surface area would take slightly longer to reach the ground than the boxes with the smaller surface areas. There were slightly different results on the same boxes because the error of the time in result which happened by partner because it was difficult to start and stop the stopwatch in same time. However, my graph shows a clear trend that the larger surface area the more time to fall.======

=
My hypothesis was correct. The more surface area made more air resistance and this effect the falling object and object took more time to drop.This effect the speed of the object and the more surface area had less speed than smaller surface area. There was some errors in my experiment because the dropping object effected by winds and other natural situations. There was some errors when I dropped the boxes, because the object in the boxes fall while the object were falling and this could effect the mass of the object.======

=
Because of the results of this experiment, I learnt more new informations about gravity and free fall by this great opportunity and this chance made me more comfortable about this science topic.I tried to show that more surface area will take more air resistance and take more time to drop.======

If I were to conduct this science fair project again I would protect my product by make my box stronger and have no spaces, because this errors made some problems in my investigation and mass is really important in my science fair. I would stop some winds and other happening by do my experiment because this things can make some impact on my experiment.

In this experiment, I found easy to drop the boxes but it wasn't really accurate because I had my experiment in outside and some natural situation impact while the object drop so it wasn't easy to make my science fair accurate. It wasn't easy to protect my products in my boxes, because their was some spaces left and there was some small holes and cereals outside while the object were dropping.
