Abstract
Concepts of scale of the Solar System are critical prerequisites for
understanding the scale and nature of the universe. Most students and adults have
difficulty comprehending how large space really is, and how large the planets
and the Sun really are compared with everyday distances and objects, and also
with how far away the Sun, Moon, and planets are from the Earth. Two hands-on
activities will be presented to address the misconception that students have about
these sizes and distances. The construction of a three-dimensional model of the
Earth and Moon system will demonstrate the size, volume, and distance between
these two objects. A second activity will involve the construction of the Sun and
planets for a true size comparison of the Solar System family.
