One of the most persistent misconceptions for students (and even adults) is just how much space is in space! Our solar system is often depicted as a bunch of planets equidistant from one another, always in a straight line.

In this activity, students will predict the scale of our solar system and the distance between planets, then check their answers using fractions. Materials Roll of
