✍️ Short Response — Use Evidence
Explain how version 2 of a storm shelter improved over version 1. Name the failure point from version 1, the redesign change, and the evidence from the same fair-test conditions that shows version 2 had more merit.

Parent note: Student wording may vary if the engineering reasoning is correct.
Multiple-Choice Answer Key
- A clear success target
- A limit the design must follow
- To choose the idea that best fits the challenge
- The important test conditions stay the same
- The weakest part that did not work well
- It should connect directly to evidence from version 1
- The claim, the evidence, and how the design met criteria and constraints
- Because it gives a reason the solution has merit
Short Response — What Success Looks Like
- Student names a real failure point from version 1.
- Student explains one redesign change and why it should help.
- Student uses evidence from the same fair-test setup to justify why version 2 had more merit.
- Student connects the improvement back to criteria such as stability or keeping the figure drier.
Short Response — Sample Acceptable Answer
Version 1 tipped over in the wind test, so the failure point was stability. In version 2, the base was widened and the supports were strengthened. Under the same fan distance and the same spray count, version 2 stayed upright and kept the figure drier, so it had more merit for the shelter challenge.
