  1. Experimental DesignHelicopter Design

  2. Bell Work- Problem • What affects the rate of descent for a paper helicopter if your only materials are one index card and one or more paperclips?

  3. Hypothesis • If ________ (number ) paper clips are added to the helicopter then the helicopter will land _____ .

  4. Materials • Paper clips • Index card • Scissors • Stop watch • Meter stick

  5. Independent Variable • Helicopter Design

  6. Dependent Variable • Average time for helicopter to land

  7. Controls • Helicopter design template • Stop watch • Meter stick • Index card • Scissors

  8. Procedures • 1. Use one 3X5 index card • 2.Use diagram to draw template of helicopter • 3.Cut along the solid lines • 4.Fold flap A forward and flap B to the back • 5.Fold flap C forward and flap D to the back. • 6.Release the helicopter 1 meter from the ground and time how long it will take to land. Do this a total of 5 times.

  9. Procedures • 7.Add 1 paper clip to the bottom of the helicopter • 8. Release and time a total of 5 times. • 9. Add 2 paper clips to the bottom of the helicopter. • 10. Release and time a total of 5 times. • 11. Average the trials for 1, 2, and 3. • 12. Graph your results

  10. Data Table Helicopter Trials

  11. What Graph do you use? • Bar Graph

  12. Conclusion • My hypothesis is correct or not___ • My independent variable is__________ • My dependent variable is ___________ • My results from the experiment showed Helicopter 1 _____ average Helicopter 2 _____ average Helicopter 3 _____ average • What did you learn from the experiment?
