Astronomy Science Fair Project

Solar System Scale Model on the Sidewalk

Solar System Scale Model on the Sidewalk | Science Fair Projects | STEM Projects
Ever wondered how far apart the planets are? Create a scale model of our solar system and learn about the sizes and distances between planets.


The hypothesis is that by creating a scale model of the solar system on the sidewalk, you can understand the vast distances between planets.

Method & Materials

You will calculate the scale distances from the Sun to each planet, and draw them with chalk on the sidewalk. If you want, you can also draw the planets to scale so that they are the correct size in relation to one another.
You will need sidewalk chalk, a measuring tape, and a calculator to calculate the distances between planets.


Walking through a scale model of the solar system is a great way to visualize the vast distances and sizes of planets. One observation that stands out is how tiny Earth seems compared to giant Jupiter!

Why do this project?

This science project is interesting because it allows students to explore the vastness of our solar system in a hands-on way. It also helps them understand how scientists use astronomical units to measure distances in space.

Also Consider

Instead of drawing the planets in a straight line, draw them in their correct positions around the Sun to create an accurate model of the solar system. Use different materials such as paper or cardboard cutouts to create a 3D model of the solar system instead of drawing it on the sidewalk.
