In this lesson, students will explore the vastness and diversity of the solar system by creating scale models of planets, moons, and other celestial objects. Using astronomical data, they will design digital 3D models with CAD software, learning to apply concepts of scale and proportion. The models will be fabricated using 3D printers and displayed in the classroom to visually represent the size relationships of the solar system.
This project integrates physics and technology, fostering interdisciplinary learning. Students will collaborate in teams, developing critical thinking, creativity, and digital fabrication skills. The final installation not only enhances understanding of scientific concepts but also inspires curiosity and appreciation for the complexity of our universe.
This list ensures smooth implementation and adequate preparation for the lesson.

Technology and Digital Fabrication Objectives:
The “ScaleSpace” lesson was a unique and engaging experience for both the students and me as their teacher. It successfully combined physics and technology, allowing students to visualize the scale of the solar system through 3D-printed models. However, the process presented several challenges that provide valuable insights for future iterations of this project.
One significant issue was the time required for 3D printing. Even with access to four Bambu Lab X1C printers, the printing process was lengthy, as the models needed to be both accurate and durable. Managing print jobs between lessons proved to be difficult. Starting and monitoring prints during school hours was especially challenging, given the limitations of class schedules and the printers’ operational needs.
Another challenge was related to group dynamics. While most students worked in pairs, some struggled to divide tasks equally. In some cases, one partner would take on most of the work, while the other became less engaged. This imbalance affected the collaborative aspect of the project and the overall learning experience for some students.
Despite these difficulties, the lesson succeeded in fostering creativity and curiosity. The students were excited to see their models come to life and proud to contribute to the final classroom display. For future lessons, I plan to address these challenges by:
Overall, “ScaleSpace” was a rewarding project that demonstrated the potential of integrating digital fabrication into the classroom. With adjustments to address logistical and teamwork challenges, it can become an even more effective learning experience.
Introduce the solar system and the concept of scale modeling.
Begin with a class discussion about the solar system, focusing on the sizes of planets and moons.
Explain how scale modeling will help represent these objects’ relative sizes.
Introduce the project: students will create 3D models of celestial objects using CAD software and 3D printing.
Have students gather size data for planets and moons.
Assign each student (or pair) a planet or moon to research.
Provide resources for accurate measurements (e.g., diameter of planets).
Have students record the data and determine how to scale it for their models.
Students will design their celestial objects in CAD software.
Introduce the basics of CAD software (e.g., Tinkercad, Fusion 360).
Demonstrate how to input measurements and create 3D models.
Students will create a scaled digital model of their assigned object, following the size data they collected.
Review and refine 3D models for accuracy and quality and prepare and print the models using 3D printers.
Show students how to convert their CAD files into printable formats using slicing software.
Help students set up their prints on the 3D printers, ensuring proper settings for size and material.
Begin the printing process, potentially after class, due to printing time requirements.
Arrange the models in the classroom to visualize their scale.
Students will work together to hang or arrange their models in order of size, showing the relative scale of planets and moons.
Display models in a central location where they can be easily viewed by everyone.
Students will present their models and reflect on the process.
Each student (or pair) will present their model, discussing the scale, design process, and scientific facts.
Encourage students to reflect on what they learned about the solar system and 3D printing.
