Students will launch the investigation by examining crystal evidence, comparing crystal formation with organism growth, refining investigable questions, and planning how they will document multiple growth trials.

Students will analyze evidence from multiple crystal-growth trials, identify patterns and anomalies, and refine evidence-based explanations. They will create and peer-review a draft before-and-after display while distinguishing nonliving crystal formation from organism growth influenced by environmental and genetic factors.

Students will defend their crystal-growth findings to an invited audience, use feedback to revise their work, and reflect on changes in their scientific understanding and collaboration.
