Astronomy Science Fair Project

Solar System Model with Foil, Play dough and a Balloon

Solar System Model with Foil, Play dough and a Balloon | Science Fair Projects | STEM Projects
In this project, you will create a solar system model to learn about the planets and their relative positions in our solar system. You can create your own version of the universe using common household items like play dough, aluminum foil, and a balloon!


The hypothesis is that by creating a model solar system, students will gain a better understanding of the planets and their orbits around the sun.

Method & Materials

You will gather materials such as play dough or clay to make planets, a balloon or larger ball for the sun, small rocks or aluminum foil for the asteroid belt and Kuiper belt, and markers or crayons, heavy paper, glue, and scissors for the Saturn's rings. Then, you will create each planet and place them in their correct order and distance from the sun, while also explaining their unique characteristics to learn about the solar system.
You will need play dough, clay, small toy balls, aluminum foil, a balloon or larger ball, small rocks, markers or crayons, heavy paper, glue, and scissors.


Through building a model solar system, students can gain a greater appreciation and understanding of our place in the universe. One observation that stands out is the vast distances between the planets and how they all work together in orbit around the sun.

Why do this project?

This science project is interesting and unique because it combines art and science to create a fun and educational activity for students of all ages. It allows students to visualize the planets and their positions in space in a tangible way.

Also Consider

1) You can try to create a model of another solar system, such as one with multiple stars or with exoplanets. 2) You can use construction paper to make a model of the solar system for a poster (see video).
