Students with visual impairment (as well as sighed students) often struggle to grasp the relative size of the Moon and the Earth and the distance between the Earth and the Moon. A majority of students greatly underestimate the distance between them.
This simple model, allows the student to build a model of the Earth and the Moon accurately representing their relative sizes and to gauge the relative distance between the two celestial bodies utilizing this model.
It would be appropriate as an introduction to the Sun-Earth-Moon System or after initial instruction has occured.
This model was adapted from The Arkansas Leadership Workshop "Hands-On Astronomy" headed by Linda S. Shore, 2008
The activiy was adapted by Jim Clark.
