Hypothesis

• I think taping the wings down will make the
  variable helicopter fall a lot slower than the
  control experiment.

3
Variable

• I will be taping the wings down for my variable
  experiment.I will be taping the wings down for my
  variable experiment.

4
Materials

• Paper helicopter
• Tape
• Timer/Clock
• Scissors
• All of these materials you will need to
  participate in this experiment.

5
Operational Definition

• I am going to time the control helicopter on its
  way down.
• Then I will do the same with my variable
  helicopter and find the differences between the
  two experiments. I will do at least two trials.

6
Procedures

• Control
• The first thing I am going to do is cut out my
  paper helicopter according to the directions on
  the cut out sheet.
• Then, without changing anything, I am going to
  drop my paper helicopter from the top of my head.
  As the helicopter is falling I am going to time
  the helicopter.
• While doing the experiment I am going to record
  my data and observations.

• Variable
• I am going to then tape the propellers down with
  tape.
• I am then going to drop the variable experiment
  from the top of my head, I am going to drop the
  helicopter. While the helicopter is falling, I am
  going to time it on its way down.
• While doing the experiment I am going to record
  my data and observations.

Observations

• The control experiment twirled a lot more than
  the variable.
• The variable experiment fell a lot slower than
  the control.
• The control flipped only once.

9
Conclusion

• I conclude that my hypothesis is correct. My
  variable fell a lot slower than my original
  experiment. I believe that happened because there
  was less pressure on the helicopter and the
  propellers werent as free as the control was.
