🛠 IE 1.6 Prototyping & ModelingComplete STEM / CTE Engineering LessonBuild, Test & Improve Engineering DesignsNGSS • CTE • TEKS • CAS • CCSS | Grades 7–10Help Students Discover How Real Engineers Turn Ideas Into Solutions

Help students think like real engineers by exploring one of the most important steps in the engineering design process:

Prototyping & Modeling

This engaging, classroom-tested, bell-to-bell engineering lesson helps students discover an important truth about engineering:

Engineers rarely build the final solution first.

Instead, engineers:

MODEL → BUILD → TEST → IMPROVE

to strengthen ideas before final production.

Students discover:

Great engineering improves through testing, feedback, and iteration.

Through hands-on engineering challenges, collaborative problem solving, engineering notebooking, testing activities, and authentic STEM design experiences, students actively begin thinking like:

Engineers • Designers • Builders • Problem Solvers

Students begin understanding:

Engineering is not about perfection — it is about improvement.
