									                                   Helicopter Experiment
Question: Do long blades or short blades work better on a helicopter?

Hypothesis: (answer the question and explain your answer)

Materials:
 Loose Leaf
 Scissor
 Paperclip

Method:
1. Make two Helicopters
2. Put a paperclip on the body of the Helicopter
3. Drop the Helicopter
4. Time them and see which one stays in the air the longest
5. Record the results
Results or Observations:

                                    Blade




Conclusion: My hypothesis was wrong. Short blades on a Helicopter work better on a
helicopter than long blades. If I would to change my experiment I would test my
Helicopters more than once.

New Question: Do even shorter blades on a Helicopter work better than just short blades?
