Students will launch the gas laws design challenge by testing rapid sealed-system phenomena, comparing their predictions to a real safety or performance case, and recording initial evidence-based claims and questions that will anchor the design brief work in the next phase.

Students will investigate existing gas-law device solutions, compare multiple design concepts with measurable criteria and constraints, and produce a stakeholder-centered decision brief that identifies a justified prototype direction, target outcomes, and controlled variables for later testing.

Students will present their tested sealed-chamber prototypes to classmates and invited community partners, defend final design decisions with graphs and trial evidence, and complete a student-led small-group reflection on how partner cases and gas-law predictions changed their design.
