Engineering Design Worksheets: Criteria and Trade-Offs gives Grade 6 science students focused practice comparing design prototypes, applying criteria, weighing constraints, and making evidence-based decisions about which solution is most promising for refinement. Built around an NGSS engineering design context, the resource moves students beyond simply choosing a design by asking them to justify their thinking.

What Students Practice

Students compare multiple prototypes using both quantitative and qualitative criteria, then use a scoring rubric or matrix to rank possible solutions. They examine how constraints influence design decisions and identify the trade-offs that can make one solution more promising than another. The emphasis is on using evidence to explain a ranking rather than relying on an unsupported preference.

The worksheet includes multiple-choice questions, true/false statements, short-answer responses, a dialogue, a matching activity, a cloze passage, a labeled diagram, a reading passage, and an essay. Together, these tasks give students opportunities to recognize design considerations, interpret evaluation criteria, communicate reasoning, and apply engineering design concepts in different response formats.

What You Receive

• Worksheet covering criteria, constraints, trade-offs, prototype comparison, scoring, ranking, and evidence-based justification
• Separate Teacher Guide PDF with learning objectives, teaching tips, discussion questions, and common mistakes

Classroom Use

Use this engineering design activity as guided practice after introducing criteria and constraints, as independent science work, or as a review of how engineers evaluate competing solutions. The varied response formats also make it useful when students need practice moving between selected-response questions, visual interpretation, written explanation, and extended reasoning.

The teacher guide supports instruction before, during, and after the worksheet by highlighting the intended learning objectives, suggesting teaching approaches, providing discussion prompts, and identifying common mistakes students may make when evaluating design solutions.

Why It Belongs in Your Engineering Design Unit

This resource centers on a key engineering habit of mind: evaluating possible solutions against criteria while recognizing constraints and trade-offs. Students are asked to connect evaluation results to a defensible choice for refinement, giving teachers a practical way to reinforce evidence-based engineering reasoning in Grade 6 science.
