Design criteria and trade-offs is the focus of this Grade 7 science worksheet on engineering and technology. Students examine how engineers define measurable requirements, work within explicit constraints, evaluate solution plans, and determine whether changes actually improve a design.

Core Engineering Thinking

This resource moves beyond simply identifying features of a design. Students practise connecting design criteria, constraints, goals, trade-offs, and evidence of improvement when evaluating engineering solutions.

• Identify measurable design criteria and explicit constraints in a design problem.
• Explain how trade-offs can affect multiple requirements in engineering design.
• Connect a solution plan to goals, constraints, and evidence of improvement.
• Distinguish improvements that meet criteria from changes that only affect appearance or convenience.

Student Practice Formats

The worksheet uses multiple-choice questions, true-or-false items, short-answer responses, a dialogue, matching, a cloze passage, a labeled diagram, a reading passage, and an essay. These activities give students opportunities to recognize engineering requirements, reason about competing requirements, and explain why a design change represents an improvement—or only changes appearance or convenience.

Teacher Support Included

• Student worksheet focused on design criteria, constraints, trade-offs, solution planning, and evidence of improvement.
• Separate Teacher Guide PDF with learning objectives, teaching tips, discussion questions, and common mistakes.

Ways to Use It

Use this Grade 7 engineering design worksheet for classroom practice, independent work, review, or guided discussion. The teacher guide supports instruction by providing prompts for discussion and practical guidance for addressing common mistakes.

For lessons on engineering and technology, the resource helps students focus on whether a proposed change satisfies measurable criteria and constraints rather than judging a design only by appearance or convenience. It gives teachers a structured way to reinforce the relationship between design goals, constraints, trade-offs, and evidence.
