# My aim is to try to find out that how much a marble (crater) would make a width and depth. And from different heights, and we are trying to find out that how much impact well it have on the sand and the effect.

Introduction

INVESTIGATION ON CRATERS.

## Prediction

I think that how much higher you go you will get a deeper depth. And I think that the width is going to be the same, because the marble is being used the same one and being used in every experiment. And I think that the depth is going to be big and the marble is going to go faster if you throw it from a longer height. And it’s going to be slower if the marble’s height is smaller.

And I think that how much higher you go, you well get a deeper depth.

Method

What I did was that I worked with a partner. What we did was that we got some sand and we added some water to make it softer, then got the basin and we added the sand into it. Then we set up the measuring apparatus, by first getting the clamp stand, and clamping the meter ruler. Then we got the marble and we then threw it from the first height. Then we took a smaller and we took the wood and laid it over the depth that the marble made before.  Then we took some string and we carefully put the string into the depth that the marble had made.  Then we marked the string and then we measured it.  Then we measured the width, but this time we measured along.  Then we carried along and threw each height, at a stage what was between 200mm.

## I could have improved my investigation by using more marbles. And using a bigger ruler to measure the height. And by using a bigger marble and more sand. And by experimenting by rocks or a brick. And I could of improved by having more sand and using more marbles. And I could of used a bigger basin so I could of put some more sand.

get into the sand by the 200g object will be bigger than the 50g object, therefore it's more accurate to use the object with the bigger mass especially when the height is small. For instance, when the height from the platform to the object is small, you can easily read the depth more accurately by using 200g objects.

Another option is that the ball could have an outer shell of hard plastic and a core of maybe rubber or plastic like the golf ball. The last option is a solid ball made of the same material through out; this is like the foam ball.
