Defining Design Problems gives Grade 6 Science students focused practice with the core thinking behind engineering design: identifying what a solution must accomplish, recognizing limits, using simple models, and comparing possible solutions.

Students work with the key terms criteria and constraints. They examine measurable requirements for solutions and explore common constraints involving materials, cost, size, time, and safety. The resource also introduces how simple models can help predict cause-and-effect relationships before a design is built, including possible effects on people, water, soil, plants, and animals.

What Students Practice

The worksheet combines a reading passage with multiple-choice questions, true-or-false statements, short-answer responses, a labeled diagram, a categorizing task, and a short note. Questions ask students to identify criteria, recognize constraints, explain why criteria should be measurable, select useful models for prediction, and describe why designers consider effects on living things and the environment.

Short-answer work gives students opportunities to create a measurable criterion for a portable shelter, identify constraints affecting a water filter, and explain how a simple model can support design decisions before construction. These tasks move beyond vocabulary recognition by asking students to apply engineering design concepts to practical situations.

Teacher-Ready Support

Students have Student Notes lines at the bottom of the worksheet for recording ideas or key learning. The Answer Key PDF includes a Teacher Guide with Learning Objectives, Teaching Tips, Discussion Questions, and Common Mistakes, giving teachers additional support for instruction and review.

This Grade 6 engineering design worksheet can be used for guided classroom practice, independent work, review, or assessment of students' ability to define design problems using criteria and constraints. The resource is identified with the NGSS framework and keeps the focus on observable engineering design concepts.

Key Learning Focus

Students identify requirements a design solution must meet, distinguish criteria from constraints, explain the value of measurable criteria, use models to consider possible cause-and-effect relationships, and explain how criteria and constraints help designers compare solutions.
