3-5-ETS1-1
The standard
Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.
Next Generation Science Standards
What this standard means
Students need to turn a need or want into a clear engineering problem. They should name what the design must do, how they will know it works, and what limits they have, such as materials, time, or budget.
Mastery looks like a student saying, “We need to build a bridge for toy cars that holds 10 pennies, spans 20 centimeters, and uses only 20 straws.” Students often get stuck by making the problem too vague, naming a solution too soon, or forgetting limits.
Ways to teach it
- Hands-on: Give teams straws, tape, and a toy car, then have them write the problem, criteria, and constraints before building.
- Prompt: Write about a classroom problem you could design something to fix, including one success goal and two limits.
- Quick assessment: Show three design statements and ask students to circle the criteria and underline the constraints.
- Real-world connection: Study a lunch tray, pencil sharpener, or backpack and list the need, success criteria, and design limits.
