Big Ideas
- Conducting fair tests is essential for identifying strengths and weaknesses in engineering designs.
- Controlling variables and analyzing failure points help engineers improve models and prototypes.
Essential Questions
- What makes a test 'fair' when investigating a model or prototype?
- Why is it important to control variables in a fair test?
- How can identifying failure points help improve a design?
- What steps can we take to test and improve our model or prototype?
- How do we decide which changes will make our design better?
