- B
A decorative model made to resemble a finished product.
- C
A paper bridge that can be placed across the test gap and loaded.
- D
A list of possible bridge concepts without any model.

- A
Keep the gap and loading method as consistent as possible between trials.
- B
Change the gap and loading method at the same time in every trial.
- C
Record the load at which the bridge bends or collapses.
- D
Compare test results with the design criteria.
- E
Record successes but leave out failures.

A bridge prototype collapses under a smaller load than the team intended. Which actions could help the team improve its design using test evidence? Select all that apply.
- A
Change one feature at a time when practical.
- B
Repeat the same load test after adding folds to the bridge.
- C
Change several features at once so their separate effects are clear.
- D
If the prototype performs poorly, consider whether the concept or understanding of the problem needs to be revisited.

A team has three bridge concepts and wants to compare load capacity, material use, and ease of assembly. Which approach best uses a decision matrix to support its choice?
- A
Pick whichever concept has the most visually appealing sketch.
- B
List the criteria, weight those that matter more, and score each concept against them.
- C
Choose the concept with the fewest parts without considering the challenge's criteria.
- D
Build every concept as a finished product before comparing them.

A team has only one idea for a paper bridge, but it has not yet compared different ways to build one. What should the team do next to explore alternatives?
- A
Choose the first idea that seems feasible and develop it without considering alternatives.
- B
Generate several approaches, then develop promising options into clearer concepts.
- C
Score one concept against the criteria before brainstorming any other ideas.
- D
Build the finished solution first, then discuss what other approaches might have worked.

A team needs to find out whether its folded-paper bridge can support washers across a gap. Which prototype would best help it learn about performance?
- A
A polished drawing, because only a finished-looking design can reveal performance.
- B
A list of materials, because listing materials tests whether the bridge supports a load.
- C
A working paper-beam model, because it can be tested under load.
- D
A final bridge made with the strongest available materials, regardless of the design being explored.

A team wants to compare two bridge designs fairly. Which test plan best supports a meaningful comparison of their load performance?
- A
Use the same gap and loading method for each design, and record the load at which each bends or collapses.
- B
Change the gap for each bridge so every design faces a different challenge.
- C
Add washers at different rates for each bridge and record only which one looks strongest.
- D
Test each bridge in a different location and compare the final number of washers.

A team uses a decision matrix to compare bridge concepts, but some scores depend on uncertain assumptions. What is the best way to use the matrix results?
- A
It guarantees the highest-scoring concept will work without needing a prototype.
- B
It lets the team choose a concept based only on personal preference.
- C
It removes the need to identify criteria because scores reveal what matters.
- D
It helps compare concepts against criteria, while the team still discusses assumptions and uses judgment.

A bridge team wants to learn whether adding folds improves load performance. Which approach will make it easiest to connect the design change to the result?
- A
Change several features at once so the next prototype differs as much as possible.
- B
Change one feature when practical, then repeat the same test and compare results.
- C
Change the loading method along with the design so the test is more varied.
- D
Avoid recording the first version's performance so the team is not biased by it.
