Students will launch the investigation by comparing mystery materials with a college chemistry partner, noticing observable patterns, and recording initial evidence-based ideas about how atomic structure may explain usefulness, safety, and behavior.

Students will refine an investigable question about everyday materials, build a testable atomic-level hypothesis, and co-design a peer-reviewed method for gathering trustworthy evidence about properties, safety, and usefulness. They will use community partner experiences, feedback cycles, and daily notebook revisions to connect observable patterns to outer electron states, periodic trends, and atomic interactions.

Students will present their Atomic Patterns Open House investigation to an authentic audience, defend a real-world claim with models and evidence cards, respond to audience questions, and complete a brief self-assessment conference that identifies growth in explaining atom behavior and one final next step.
