Atomic Architecture: Designing the First Sustainable Martian Colony
Grade 10Science20 days
In this project, 10th-grade students act as chemical and aerospace engineers to design a sustainable Martian colony by leveraging their understanding of atomic structure and periodicity. Students analyze periodic trends and chemical bonding to select building materials and engineer life-support systems, such as the Sabatier process, for oxygen and fuel production. By tracing the cosmic origins of Martian minerals and investigating intermolecular forces, they develop a closed-loop habitat capable of withstanding extreme environmental conditions. The experience culminates in a technical proposal that justifies complex engineering decisions through the lens of chemical properties and materials science.Atomic StructurePeriodic TrendsMaterials ScienceChemical ReactionsNucleosynthesisSustainable DesignSpace Exploration

Entry Events
Events that will be used to introduce the project to studentsThe Mars Real Estate Expo: Building from Nothing
Students are invited to a virtual 'Martian Real Estate Expo' where they must evaluate three different landing sites based on the geological and chemical data provided (ESS standards). However, they quickly discover that 'Earth-standard' materials (like steel or traditional plastics) are too heavy to transport, forcing them to brainstorm how to manipulate the atomic properties of Martian dust and thin atmosphere to 'grow' their own infrastructure.đź“š
Portfolio Activities
Portfolio Activities
These activities progressively build towards your learning goals, with each submission contributing to the student's final portfolio.Activity 1
Structural Integrity: Atoms in the Extreme
On Mars, temperatures swing wildly and the vacuum is unforgiving. Students will investigate how different types of chemical bonds (ionic, covalent, metallic) and intermolecular forces (IMFs) dictate how materials behave at 'bulk scale.'

Cosmic Prospectors: Mapping the Martian Mines
Before building, students must understand what resources are available and why. In this activity, students trace the 'cosmic history' of five key elements found on Mars (e.g., Iron, Silicon, Magnesium, Oxygen, and Carbon). They will research how these elements were created in stars and how Martian geological processes concentrated them in specific landing sites.Steps
