Worlds in Comparison
Young astronomers follow a step-by-step procedure for dividing a lump of dough into parts, resulting in a scaled volume set of puny planets. Along with the printable directions is a template chart of planet names on which learners can...
Curated OER
Solar System Hall Model
Not novel, but fun, this activity gets your space science learners to model the size of the planets and the solar system along your school's hallway. Scaled measurements as well as actual distances are provided for both planet diameters...
Curated OER
Solar System
Second graders create planet mobiles in order to reinforce concepts such as planet size, position in relation to the sun, and planet names.

Nasa: Planet Quest: Extreme Planet Makeover
Activity in which students create a planet based on distance from a star, age, size, and star type. The created planet is evaluated to determine if it can support life.
University of California
Uc Berkeley: At Home Astronomy: The Size and Distance of Planets
In this activity, "You will investigate the concepts of relative size and distance by creating a basic model of our solar system." Planet printouts are provided and this site contains related links.
