Aim
The aim of this experiment is to find out how the height that a ball is dropped from affects the size of a crater.
Preliminary experiment
To help us know how to complete the final experiment that will find us varied accurate results we have completed a preliminary experiment to test out, what size ball should be used, what substrate the ball should be dropped into and the differences in height the ball should be dropped from. ... We noticed that the imprint on the crater in sand and sugar was ruined as particles of the substance rolled in filling the crater up. We realised by measuring the size of these craters the result would be unjust and not a fair test. ...
The next thing we wanted to decide was the size, type and shape of the ball. ... Our group decided to complete the final experiment with the golf ball which made a small but measurable crater. ...
Golf ball – this is the ball used to be dropped and form the crater. ...
Metre stick – This will be used to measure the height of the clamp where the ball is dropped from
Splint – the splint is used for accuracy in measuring the size of the crater and will put it in the crater mark the bottom and then measure the length. ... The dependant is the size of the crater. So in this instance we will do this by keeping the size, mass, and shape of the ball the same. ... We have decided that we want the flour to be light, fluffy and not compressed to make a bigger crater, this is due to the fact that when the flour is not compressed, there is more air in the flour and it is less dense so when the ball lands into the substrate it displaces the air and the force against the ball is less, therefore causing a bigger crater.
