Five E(z) Steps to Teaching Earth-Moon Scaling
In this activity, students critically analyze prior conceptions and textbook visuals of the relative sizes and orbiting distance of the Earth-moon system (and other bodies in our solar system), search out sources for this data, and construct scale models by using balls of various sizes. There are tips for helping learners understand the large scales (i.e., millions rather than thousands) that characterize our solar system, and examples are provided of scaling using different sizes of athletic balls.
