Ignoring the data
Repeating the experiment without analysis
If your hypothesis is not supported by the experimental data, what should you do next?

Submit the prototype as is
Which of the following best demonstrates the use of iterative design or redesign in engineering?
Building a single prototype and never changing it
Repeatedly testing and improving a design based on feedback
Skipping the testing phase
Only using computer simulations
A student is designing a bridge and wants to test different materials. What is the best way to analyze which material is strongest?
Test each material under the same conditions and compare the results
Use only the cheapest material
Guess based on appearance
Choose the material used in most bridges
A team is evaluating their prototype after several tests. What should they do to ensure their evaluation is thorough?
Only consider successful tests
Review all test data and compare it to the design criteria
Ignore failed tests
Focus only on appearance
You are tasked with designing a water filtration system for a rural community. Describe how you would use the engineering design process to develop and test your solution, including how you would analyze data and iterate on your design.
Build a prototype and hope it works
Identify the problem, brainstorm solutions, build and test prototypes, analyze data, and improve the design based on results
Only research existing solutions
Skip testing and go straight to production
You have built a prototype wind turbine. Describe a strategic plan for testing its efficiency and using the results to improve your design.
Test once and record the result
Test under different wind speeds, record power output, analyze data, and modify blade design based on findings
Only test on a windy day
Skip data analysis
A team is developing a new smartphone case. How should they use prototyping and testing to ensure the final product meets user needs?
Build one prototype and sell it
Create multiple prototypes, test for durability and usability, gather user feedback, and refine the design
Only focus on appearance
Ignore user feedback
Explain how iterative design principles can be applied when a prototype consistently fails a specific test. What steps should be taken?
Ignore the test results
Analyze why the prototype fails, brainstorm improvements, modify the design, and retest until the issue is resolved
Only change unrelated features
Stop testing
A student is testing a new type of insulation. How should they plan their experiment to ensure reliable and valid results?
Test only once
Use controlled conditions, repeat tests, and compare results to a standard insulation
Only test in summer
Guess the outcome
Describe how you would use data analysis to improve a prototype after initial testing reveals inconsistent results.
Ignore the inconsistencies
Identify patterns or sources of error in the data, adjust the prototype, and retest to see if consistency improves
Only use the best result
Change the data
You are tasked with designing an experiment to compare two different battery types for use in a new device. What steps would you take to ensure your results are valid and useful for decision-making?
Test each battery once
Test both batteries under identical conditions, record performance data, analyze results statistically, and repeat tests for reliability
Only use the cheaper battery
Guess which is better
After planning and building, the next step to the desing process is to...
find a problem
find a solution
test and improve the prototype
redesign
True or False: When a prototype fails you should start over
True
False
A key part of the engineering and design process is that it is...
Iterative/ Cyclical

Brainstorm
Come up with multiple ideas that can solve your problem
Choose the most Promising Solution
Choose the best solution out of the ones you brainstormed
Prototype
Create a physical model of your solution
If your prototype does not work the first time you try it you should give up.
True
False
Which of the following best explains why engineers test multiple prototypes during the design process?
To avoid analyzing data
To waste materials and time
To identify the most effective solution and improve designs based on test results
Because they are unsure of the problem
What should you do if your experimental data does not match your hypothesis during the engineering design process?
Change your data to fit the hypothesis
Revise your hypothesis or design and conduct further testing

When analyzing test results from a prototype, which approach is most effective for making improvements?
Choose the design that looks best
Review all data, identify weaknesses, and adjust the design accordingly
Focus only on successful outcomes and ignore failures
Repeat the same test without changes
Why is it important to analyze both successful and failed test results during the engineering design process?
To ensure all aspects of the design are evaluated and improvements are based on complete information
