Students will investigate real playground motion and accessibility, learn core forces vocabulary through hands-on examples, and begin the engineering challenge by recording evidence, criteria ideas, and a first design direction for an inclusive playground model.

Students will investigate user needs, forces, and real-world playground examples so they can define measurable criteria and constraints, compare possible solutions with evidence, and write a team design brief for an inclusive playground model.

Students will compare multiple playground concepts with a simple weighted decision matrix, choose one design using evidence from criteria and constraints, build a rapid scale prototype with moving parts, and test it with a repeatable procedure to collect data about motion, stability, safety, and inclusive play.

Students will use test data and feedback to revise their playground models, prove improvement with retesting, and prepare a concise engineering story for stakeholders while completing a forces assessment and weekly reflection.

Students will present their revised scale inclusive playground models and engineering evidence to families, peers, and school stakeholders, demonstrate how pushes, pulls, gravity, and stability shaped their design choices, gather audience feedback, and complete a final reflection on how testing, critique, and revision improved their work.
