53 Solar System Project Ideas for Elementary Students

Solar system projects work best when students get choice, structure, and clear expectations. When projects connect to how students learn best—through art, movement, research, or games—they stay engaged and produce stronger work. These ideas are designed for upper elementary classrooms and homeschool settings where students are building content knowledge, explaining scientific ideas, and applying what they learn.

Below you’ll find classroom-tested solar system project ideas organized by learning style. These projects fit easily into a space unit, science fair preparation, or end-of-unit assessment.

Build Background Knowledge Before Starting a Solar System Project

Solar system projects are more successful when students understand the basics before they begin. Students need shared language and common facts so their projects show understanding, not guesswork.

Before assigning a project, students should know:

• The order of the planets
• Basic characteristics of each planet
• How rotation and revolution work
• The role of the sun
• Vocabulary tied to space science

Spending time on background knowledge leads to clearer explanations, better models, and stronger presentations.

Here are a few ways teachers can build background knowledge about the solar system before having students choose a solar system project of their own:

Solar System Informational Articles for Grades 3-5

Using short, focused informational texts helps students gather accurate facts before choosing a project. Reading passages give students access to scientific vocabulary, clear explanations, and reliable information they can reference during research and writing.

These solar system articles focus on:

• Each planet
• Pluto and dwarf planets
• The sun, moon, and stars
• Key space science concepts

They work well for whole-group lessons, small groups, or independent research and support students who need structure while learning new content.

Science Stations for Rotation, Revolution, Day, and Night

For older elementary students, hands-on science stations build understanding of movement in space. Stations focused on Earth’s rotation, revolution, seasons, and the moon’s orbit help students visualize concepts they will later explain in projects.

Stations are a strong option for fifth grade classrooms and align well with space science standards that focus on patterns and relationships in the Earth–sun–moon system.

Let Students Choose a Solar System Project

Choice increases motivation and improves the quality of student work. When students select a project that fits how they learn best, they spend more time thinking, revising, and explaining their ideas.

Students might:

• Build a model
• Create artwork
• Research and write
• Act out scientific concepts
• Design games or challenges

The goal is not one perfect project format. The goal is meaningful learning paired with clear science explanations.

Here are some solar system projects your students can complete for classroom projects or homeschool explorations:
