How Big is the Moon - Activity

Have you ever wondered how big the Moon was relative to the Earth? Since it is not possible to shrink the Earth and Moon, the following activity allows you to gain a better understanding using a piece of string and some image cut outs. This activity also allows you to use a regulation size basketball and a tennis ball to represent both the Earth and the Moon. By wrapping a piece of string around the 'equator' part of the basketball 9.5 times, this will be equivalent to the distance you would have to place the tennis ball at to have an accurate scale model.

For more information and images on how to do this activity please visit.
