Students will launch the unit by setting up the coding environment, running and modifying a first Python program, analyzing what makes a simple program clearer for users, and recording an initial coding journal entry that sets up later design, feedback, and revision work.

Students will investigate what makes a Hello World upgrade useful for a real audience, study and compare sample Python programs, define measurable design criteria and constraints, generate multiple solution concepts, and select a justified approach using evidence before building.

Students will build and test a first working Python prototype, collect evidence against their design criteria, revise based on peer and user feedback, and document the engineering decisions that prepared them for the final showcase and walkthrough.

Students will present their revised Python Hello World programs to an authentic audience, explain how feedback and testing improved the design, and document their learning through a brief coding journal and live walkthrough.
