Plan
When meteors hit the moon's surface it creates craters; we can represent this by dropping small balls into a tub of sand. By dropping the ball from different heights we can test how this affects the size of the crater and recreate what happens on the moon.
In the first experiment I got a tub of sand a ball, and a meter ruler. I will set the ruler sticking up from the tub of sand using a clamp. I will then level off the sand and drop the ball from 10 cm above the surface of the sand. This will make a crater in the sand and I will measure the diameter of this with calipers.
To keep it a fair test I will only have one variable, this being the height that the ball is dropped from. I will keep the size and mass of the ball the same, the tub of sand the same, and the ruler the same. I will measure the crater using calipers. I will measure the diameter of the crater across in different places to make sure that I have an accurate reading. View diagram below to see this.
