Scientific laws are discovered when

generalizations for how the world behaves can't be disproved

Which question would be asked for technological rather than scientific reasons?

How can hydrogen fuel be used to power cars?

Scientists hypothesize in order to explain

What they think will happen in a certain situation

During the process of peer review, scientists read other's works for all EXCEPT:

determining if they can sell to the highest bidder

Which of the following statements is not an example of evidence?

The liquid was identified as water because of its appearance

Technology is the application of

science to design a new product or process

an explanation of observable events with no exceptions

All of the following qualities help ensure scientists' success except

the desire to answer a problem as quickly as possible
