Parent note: Student wording may vary if the engineering reasoning is correct.
Multiple-Choice Answer Key
- It names the need and what success should look like
- A limit the design must follow
- To choose the idea that best fits the criteria and constraints
- The drop height and object stay the same
- The weakest part that did not work well
- It should connect to evidence from version 1
- The problem, solution, criteria, constraints, and evidence
- Because it includes specific test or redesign evidence
Short Response — What Success Looks Like
- Student names the challenge or problem clearly.
- Student describes one specific redesign change.
- Student cites test evidence showing why version 2 is stronger.
Short Response — Sample Acceptable Answer
“My problem was protecting a fragile egg during a drop. I changed version 2 by adding stronger side supports and extra padding where version 1 bent. The evidence is that version 2 held its shape better and the egg moved less during the same drop test.”
