Big Ideas
- Effective engineering design requires fair testing to improve prototypes and models.
- Analyzing test outcomes helps identify how and where a design can be improved.
Essential Questions
- What makes a test fair when evaluating a model or prototype?
- Why is it important to control variables during testing?
- How can identifying failure points lead to improved designs?
- What methods can we use to determine which aspects of a prototype need improvement?
- How does testing and refining a design contribute to the engineering process?
