She skipped the step of asking “What if?”
She wasted her time by repeating the same test.
She obtained unreliable data, because there were more chances for mistakes.
She obtained more accurate data than if she had only tested the reflector once.
You probably use the tools shown below every day.
Which statement about these tools is true?
They cost about the same to produce.
They are both examples of technology.
They are examples of identical technology.
They are each designed for many different tasks.
Sometimes, a prototype tests poorly or fails completely. What should be done when that happens?
The prototype should be abandoned.
A second prototype should be built.
The prototype should be modified, with the good parts of it kept.
The prototype should be examined to see if it has other uses.
A fuel-efficient automobile is an example of a designed system. What is an example of feedback for such an automobile?
safe arrival at the destination
fuel for the car and the roads on which it will travel
data on how much fuel the car used to travel 100 km
