Build a Scale Model of the Solar System




Looking for an extension activity for your astronomy and Earth’s place in the universe unit? Do you need a hands-on way for students to extend their learning and make more sense of the scale of the solar system and beyond? If so, this Solar System Model Activity is the perfect resource for you!


This activity is designed to support the following NGSS standards:

MS-ESS1-2 Develop and use a model to describe the role of gravity in the motions within galaxies and the solar system.

MS-ESS1-3 Analyze and interpret data to determine scale properties of objects in the solar system.


In this activity, students will create a solar system model using one of two provided versions (one that can fit in the classroom, the other requiring a lot more space, ideally a football field). A variety of options for materials are also included


Questions that accompany this activity prompt students to consider the limitations of models and the importance of scale in developing a model of the solar system and beyond.


Who is this resource for?

This resource can be used by classroom teachers, tutors, and parents of students in grades 6-9.
