What is a situation when scientific method can be apply?

Try to see if a paper airplane will fly farther with 5 paperclips on the nose as opposed to 0,1,or 3.

Question: Will the # of paperclips on the nose of a paper airplane cause the plane to fly farther?

Hypothesis: 5 paperclips on the nose of a paper airplane will make he plane fly farther than with 3,1,or 0 paperclips on the nose.

Experiment: Make paper airplanes and fly them with 0 paperclips on the nose. Repeat this test 3 times. Record about how many meters each test flew. Repeat this with 1 paper clip, than 3 paperclips, and finally 5 paperclips.

Analyse: Record the average of the 3 tests. write down the steps you took in completing the experiment. Also write down the controlled, dependent, and independent variables of the experiment.

Conclusion: 5 paperclips on the nose of the paper airplane will make the plane fly farther than with 0,1,or 3 paperclips on the nose.

Compare: Compare the averages, variables, and steps taken along with any other data, to that of other scientists. Remember, a valid experiment can be repeated with duplicated results.
