In this activity, learners make a scale model of the Solar System and learn the real definition of "space." Learners use the online calculator to create an appropriate scale to use as a basis for their model. Once learners have their scaled measurements (diameters and distances), then they can walk and "pace out" the solar system by marking sticks or flags in the ground. Learners can also build a solar system on a roll of toilet paper or receipt paper.
