The problem question in Bonita’s experiment is that: will the addition of mass to the paper helicopter affect the stability of the helicopter in the air?
Bonita's hypothesis is that if additional paperclips are added to the helicopter, then the helicopter will be stabilized resulting in a longer flight time.
The experiment requires one to refold the blades of the helicopter, and one drops the helicopter several times and observed
the results. These repeated trials enable one to be more confident of ones results.
Bonita should retest her experiment to make sure her results are reasonable, valid and repeatable
An experiment is a procedure taken to affirm or refute a hypothesis, or determine the potency or likelihood of something previously untried. Experiments suggest insight into cause-and-effect by demonstrating what result occurs when a particular factor is manipulated.
Therefore, the correct answer is as given above
