⚙️ Why Teach Prototyping Methods?
Prototyping is a fundamental step in the engineering design process. Students learn that prototypes allow engineers to explore ideas, identify weaknesses, gather feedback, and improve solutions before creating a final product. Understanding different prototyping methods encourages critical thinking, creativity, and evidence-based decision-making while helping students appreciate how successful products evolve through repeated testing and refinement.

🔬 Students Will Learn To:
• Explain the purpose of prototypes in engineering design
• Identify different prototyping methods used to test ideas
• Compare low-fidelity and high-fidelity prototypes
• Recognize the advantages and limitations of various prototype types
• Understand how testing informs design improvements
• Analyze engineering decisions using evidence from prototype testing
• Strengthen scientific reasoning and problem-solving skills
• Connect classroom learning to authentic engineering applications

💡 Perfect For:
• NGSS Engineering Design lessons
• Grade 9 Science classrooms
• STEM activities and projects
• Technology and engineering courses
• Bell ringers and warm-ups
• Independent practice
• Guided instruction
• Homework assignments
• Review lessons
• Assessment preparation
