Engineering Design Process: Criteria, Constraints & Models is a Grade 10 Science worksheet focused on how engineers define complex problems, establish measurable goals, compare solution concepts, and improve designs through modeling and iteration. Aligned to the NGSS framework, it gives students structured practice with criteria, constraints, performance metrics, stakeholders, benchmarks, models, and prototypes.

What students work with

Students distinguish qualitative design criteria from quantitative performance targets and connect each to measurable outcomes. They examine how constraints such as cost, available materials, and safety requirements shape feasible solutions. The lesson also addresses stakeholder needs, multiple solution concepts, shared benchmarks, prototype testing, and iterative design decisions.

Realistic examples include water purification systems and solar-powered devices. Students consider goals such as safety, maintainability, purification rate, and efficiency, then examine how those goals can become measurable performance metrics for testing and comparison.

Student activities

• Dialogue activity focused on engineering design thinking
• Matching task connecting key engineering design concepts
• Cloze passage using criteria, constraints, targets, metrics, models, solution concepts, and benchmarks
• Labeled diagram activity representing the design process
• Reading passage on criteria, constraints, measurable targets, models, prototypes, stakeholders, and iteration
• Multiple-choice questions requiring students to distinguish concepts and apply them to engineering scenarios
• True-or-false statements that check understanding of benchmarks, prototypes, quantitative targets, criteria, and constraints
• Short-answer responses addressing stakeholder influence, qualitative and quantitative goals, and benchmark-based comparison
• Extended response requiring an engineering approach for a solar-powered evening lighting device

Classroom-ready support

Use the worksheet for science instruction, independent practice, review, discussion, or written assessment of engineering design concepts. The extended response gives students an opportunity to bring several ideas together by defining criteria and constraints, selecting performance metrics, explaining model or prototype use, and describing how benchmarks can guide a final design choice.

A separate Teacher Guide PDF is included with Learning Objectives, Teaching Tips, Discussion Questions, and Common Mistakes. This gives teachers practical support for introducing the vocabulary, prompting evidence-based comparisons, and addressing common misconceptions while students work through the resource.
