Synopsis
In this lesson, students apply research and defined constraints to design, sketch, and build a prototype that addresses a problem identified in Lesson 4. Students work together to learn how evidence and testing improve designs.
Inquire: Students learn how constraints shape design.
Investigate: Students use research to sketch, evaluate, and refine multiple design ideas, then select a design to build a prototype.
Inspire: Students build a prototype, document challenges and changes, and reflect on how it matches their design sketch.
