Copter Experiment Your Name Mr. Garcia E-106 Fall 2010
Problem The effect of blade size on the flight of a paper copter
Question Will changing the size of a paper copter’s blades change the flight time of the copter?
Hypothesis Predicting=Your educated guess as to a future event based on past experience. Think about the video we saw on flight dynamics.
Hypothesis 5 sentence minimum Which copter will be the best? Why? Research/Video support from the video: Scientific American “Science of Flight” Hosted by Alan Alda
Materials Paper Scissors Templates Stop watch String Metric rulers/meter stick Chair
Procedure Copter A Construct copter A. Cut out and fold as directed. Practice flying copter A. Conduct 20 trials dropping copter A from a height of 200 centimeters. Measure flight time in seconds to the nearest hundredth of a second.
Procedure Copter B Construct copter B. Cut out and fold as directed. Copter B will have blades that are twice as wide as Copter A. Practice flying copter b. Conduct 20 trials dropping copter B from a height of 200 centimeters. Measure flight time in seconds to the nearest hundredth of a second.
Procedure Copter C Construct copter C. Cut out and fold as directed. Copter C will have blades that are twice as long as Copter A. Practice flying copter C. Conduct 20 trials dropping copter C from a height of 200 centimeters. Measure flight time in seconds to the nearest hundredth of a second.
Experimental Setup The manipulated variable is the blade size. The control in this experiment is copter A, the recommended blade size. Variables that remain constant include the same paper, same drop height, same room environment, and the same procedure will be followed for each flight.
Experimental Setup The responding variable will be the flight time of the copters. We will measure our units in seconds to the nearest hundredth and will average our results for each copter to get a mean for copters A, B, and C.
Observations A-B-C In each of these paragraphs you need to include the following: observation of the flight including characteristics of each copter -drop, rotation/spin mean flight time outliers (high and low values) range (high flight time-lowest flight)
Results In this paragraph you need to include the following: Record of mean flight times for copter A, B, and C. Compare. Comparison of characteristics for copter A, B, and C. -drop, rotation/spin
Conclusion In this paragraph you need to include the following: Restate your hypothesis Evaluate your hypothesis Offer an opinion as to your results. Why was your hypothesis proven or disproven?
Scientific Method Ask a question. Conduct research. Form hypothesis: possible explanation for a set of observations…educated guess. Design an experiment to test your hypothesis.
Scientific Method Experimental Procedure Variable Manipulated variable Responding variable Controlled experiment
Scientific Method Variable: any factor that can change in an experiment Manipulated variable: the factor that you change in an experiment Responding variable: the factor that changes as a result of the manipulated variable. Controlled experiment: all factors besides the manipulated variable are kept constant.
Scientific Method Interpreting Data Must include observations and measurements Data should be organized in charts and graphs Analyze your data Drawing Conclusions Restate your hypothesis Evaluate your hypothesis Make further predictions based on your outcome.
