__Does Changing The Height Of The Marble Dropped Affect The Diameter of The Marble?__


 * Question~** How does changing the height of the marble at which it is dropped affect the diameter of the crater?


 * Hypothesis~** If we change the height at which the marble is dropped, then the diameter of the crater will increase or decrease because the higher the marble is dropped, the more force there is on the sand.

As a conclusion, our hypothesis was correct. The higher the height in which the marble is dropped, the larger the diameter will be of the crater. As in the results it shows that dropping the marble from a height of 60 cm had an average of 4 1/2 diameter of the crater, while dropping the marble from 20 cm high had the smallest diameter. Errors we had was the marble kept hitting the side of the container and the reading wasn't accurate so we had to do a couple of trials over. Another error was the marble occasionally missed the container and it would not get to the sand and make a crater. The new problem should be does changing the diameter of the marble dropped affect the diameter of the crater.

 * Question~** How does changing the diameter of the marble dropped affect the diameter of the crater?


 * Hypothesis~** If we change the diameter of the marble, then the diameter of the crater will increase of decrease because, the bigger the diameter the bigger the crater.

As a conclusion, our hypothesis was correct. If the diameter of the marble is greater, the diameter of the crater will increase. As in the results, is the diameter of the marble is 2 cm, the greater the crater will be with an average of 4 4/5 cm and the 1 cm in diameter marble had the smallest averages of craters with only 3 1/3 cm. Errors we had was the marble kept hitting the side of the container and the reading wasn't accurate so we had to do a couple of trials over. Another error was the marble occasionally missed the container and it would not get to the sand and make a crater. The new problem should be whether changing the surface in which the marble falls on, will it create a smaller or larger crater.
 * Conclusion~**


 * Analysis Questions~**

The speed affects the size of the crater because the higher something is, the more velocity, until the object reaches terminal velocity. Since height increases, the speed at which an object falls is greater and the impact is greater due to action and reaction forces.
 * 1.) How did the speed of the marbles affect the size of the crater? (Support your answer with data)**

We also tested the effects of different sizes of marbles and the size of craters they make. We found out that the bigger the marble is in diameter, the greater the diameter the crater is.
 * 2.) How did your other factor affect the size of craters?**
