A visit to the moon

During our space inquiry we have been talking about the moon and what we know about it. Some of us knew the moon has craters and we wondered how these might have been made. We learnt that the moon is made of rock but can have a dusty surface so we got some trays of flour to act as the moon's surface and tried to recreate some craters of our own. 

We used some different objects, a small marble and larger marble, a polystyrene ball and a tennis ball. We thought about which one would make the biggest crater and everyone agreed the tennis ball would make the largest crater. We also thought about which would make the deepest crater. Most of us thought the big marble would make the deepest one. 

We took turns dropping the balls from different heights into the flour and creating craters of our own. 

We made a discovery that the small marble actually made the deepest crater which we think was because it was a bit heavier than the bigger marble. 

I wonder how big the objects were that created the craters on the moon?

We also talked about the different phases of the moon and how it appears to change shape. 

 Keep a look out this month to see how the moon's shape is changing each night.
