This is an activity that I use when I teach students about the size and distances in our solar system. It is one of the activities that I use to meet Next Generation Science Standard # MS-ESS1-3 (Analyze and interpret data to determine scale properties of objects in the solar system)
When I do this we use long cash register receipt paper (about 2-3 feet per student) but I have also done it using long white construction paper (12x18) that I cut into strips. In our class we attach our completed strips into our interactive notebook, so the students can refer back to it as needed. As one of my follow up activities/assessments I ask student to create their own model that represents properties of the solar system-- distance between planets is one of the properties they can choose to model.
I don't pass out a handout with this - I have found it works best when their attention is on me and the instructions, and I hate to waste paper. It could be used as a center if you run those in your science class.
The questions on the last slides of the power point are for our discussion at the end of the model building activity. Sometimes I use them for an exit question card as well. Every year students are amazed at how far away things are.
Please let me know if you have any questions; feel free to email me with issues.
