The children have been learning about the force of gravity, by working in groups to simulate the impact craters left behind following meteor impacts. The children used different objects, of differing mass but of a similar size and measured the diameter and depth of the crater left behind. They found that the mass of the object was important. The steel ball bearing left a far larger crater than the chick peas and glass marbles.
We used Google Earth to find impact craters on our planet. There are plenty to be found, if you know where to look. Some of Canada’s finest lakes are in fact impact craters.
