Design Criteria and Constraints are at the heart of this Grade 3 Science engineering design worksheet, helping students examine what a solution needs to do, how success can be measured, and what limits must be considered.

Students work with engineering design scenarios to define design criteria and constraints, identify a desired function, recognize measurable success measures, and describe trade-offs between competing requirements when selecting a solution. The resource gives students practice applying these ideas rather than simply recalling definitions.

What Students Practice

• Identify the desired function of an engineering solution.
• Distinguish design criteria from constraints in a given problem.
• Recognize measurable ways to determine whether a design succeeds.
• Describe limits that affect an engineering design.
• Explain trade-offs between competing requirements when choosing a solution.

Question and Activity Variety

The worksheet uses multiple-choice questions, true-or-false statements, short-answer responses, a dialogue, matching, a cloze passage, a labeled diagram, a reading passage, and an essay. This variety gives students different ways to demonstrate their understanding of engineering design criteria, constraints, success measures, and trade-offs.

What You Receive

• Student worksheet focused on Design Criteria and Constraints for Simple Engineering
• Separate Teacher Guide PDF with learning objectives, teaching tips, discussion questions, and common mistakes

Classroom Use

Use this engineering design worksheet for science instruction, guided practice, independent work, review, or assessment. The teacher guide provides practical support for introducing the concepts, prompting classroom discussion, and addressing common mistakes as students work through design scenarios.

For teachers introducing engineering design in Grade 3, this resource connects key vocabulary to realistic decision-making. Students consider what a design should accomplish, what limits it, how success can be measured, and why choosing one requirement may involve giving up another. The result is focused practice that supports clear reasoning about design criteria and constraints within an NGSS-based science context.
