Which statement best describes an 'innovation' in engineering?
30
Creating something brand new that no one has ever thought of
Taking an existing idea or product and improving it in a meaningful way
Testing a prototype multiple times to see if it works
Writing down all the steps of the engineering design process
Q 2/27

Why is it important to identify your 'target audience' before designing a product?
30
So you know how many prototypes to build
So you can decide which tools to use in the makerspace
So you understand who will use your product and what they need from it
So you know how much money to spend on materials

Q.
You are testing two different Rube Goldberg designs. Design A uses 8 steps and takes 12 seconds to complete. Design B uses 5 steps and takes 8 seconds to complete. Both successfully move a marble from start to finish. Which design better meets the criterion of efficiency, and why?

Q.
During testing your Rube Goldberg machine, you discover that your marble rolls off the track at the third step. You have already built the entire prototype. What should be your NEXT action?

Q.
You are comparing three prototype designs that all meet the basic requirements. Design X costs $8 and works 80% of the time. Design Y costs $15 and works 95% of the time. Design Z costs $5 and works 60% of the time. If your constraint is a budget of $10, which design best balances cost and reliability?

Q.
Two students are designing a Rube Goldberg machine. Student A sketches detailed plans before building. Student B starts building immediately without sketching. How will Student A's approach likely affect the design process?

Q.
Your Rube Goldberg machine must move a marble 10 feet and cost less than $12. After testing, you find it only moves the marble 6 feet. Which statement best describes this situation?
23

Q.
You are analyzing data from testing three different ramp angles (30°, 45°, and 60°) for your marble machine. The 45° angle allows the marble to travel the farthest before stopping. What should you do with this information?

Q.
You notice that combining the best features from two different prototype designs creates a machine that works better than either original design alone. What engineering process are you demonstrating?

Q.
Your constraint is that your Rube Goldberg machine must fit in a box that is 2 feet × 2 feet × 2 feet. Your current design is 3 feet long. How should you respond to this constraint?
