ExperimentEngineering Constraints and Criteria
What You'll Learn
Engineers must consider constraints (limitations like cost, time, and materials) and criteria (requirements the solution must meet) when designing solutions to problems.
Key Words
- design
- constraint
Materials Needed
- rubber bands
- string
- cups
- aluminum foil
- ruler
Safety First
- Clean up spills immediately to prevent slipping.
- Use materials only as directed in the experiment.
- Keep small objects away from young children.
