Noah is trying to solve a problem and wants to make a solution using materials he has available. Which process would he use?
Engineering Design Process
Experimental Design Process
Harper wants to figure out the answer to a question about plant growth. Which process would she use?
Engineering Design Process
Experimental Design Process
What is the benefit of repeating experiments multiple times?
Repeating experiments is a waste of resources.
One experiment is enough to draw conclusions.
Experiments should be repeated only if the initial results are unexpected.
Repeating experiments helps to confirm the consistency and accuracy of the results.
Why should you list your design criteria before starting the prototyping phase?
To expedite the prototyping phase without any prior planning.
This helps make sure the project aligns with objectives, minimizes revisions, and gets you the solution you were wanting.
To focus solely on the visual aspects of the prototype.
To prevent any user input during the design process.
