Section+2+investigation+into+cratering


 * __Our investigation __**


 * What does our data reveal about the relationship between crater size and impactor velocity? **


 * Independent variable: Height **
 * Dependant variable: size of crater. **
 * Control variable: Mass, smoothness of maize **
 * Mass of ball:48.17g **

· **Firstly, we filled the pan with maize flour using a sieve and we smoothed it out. ** · **Then, we measured out the height and dropped the ball from that height (starting at 25 cm). ** · **When we dropped the ball we measured the size of the crater it created. ** · **After that we smoothed out the surface again and repeated the experiment 5 more times. **
 * Method: **
